# Run read-only SQL over your events

> Ask your agent to run one read-only SELECT over a project's own events inside a window of at most 92 days, and read typed rows back through MCP, the CLI or REST, with every limit, refusal and value encoding stated.

Canonical page: https://anectico.com/docs/investigate/sql/


SQL answers a question the built-in measurements do not ask. Your agent runs **one read-only
`SELECT`** over a single table, `events`, that holds your project's own events inside a window you
choose, and reads typed rows back. Nothing is saved, nothing is changed, and every run is recorded
in your organization's audit log. SQL is a tool for your agent and a command for the CLI. The
Console has no SQL page.

## Ask your agent

> "Which 10 event names were the most frequent in this project over the last 7 days? Use read-only
> SQL and show me the counts."

> "How many `checkout_completed` events did we receive each day last week? Group them by the
> `$currency` property."

| Job | MCP tool or action | CLI command |
| --- | --- | --- |
| Read the `events` table description, the SQL dialect, the limits and the error codes | `get_analytics_sql_capabilities` | `anectico analytics sql capabilities` |
| Run one read-only `SELECT` inside a window | `execute_analytics_sql` | `anectico analytics sql run` |

The key needs `analytics:sql`, `analytics:read` and `persons:read`, and `mcp:read` over MCP. An agent
connected by sign-in approval (OAuth) does not hold `analytics:sql`. Give that agent an API key
whose creator holds it. See [Permissions](#permissions).

## Open the proof

SQL has no proof page. A SQL result is not frozen, not saved and not a selection of people, so no
page could show exactly what it claims, and the tool returns no link. When a person needs to open
and check a result, ask your agent for a built-in measurement instead: its result opens as a
read-only page. See [Measure product events](/docs/investigate/product-analytics) and the
[result viewer](/docs/agents/result-viewer).

## When to use SQL, and when to use a measurement

Start with the built-in analyses ([trends, funnels, retention, engagement and the rest](/docs/investigate/product-analytics),
[web analytics](/docs/investigate/web-analytics), [revenue](/docs/investigate/revenue) and
[heatmaps](/docs/investigate/heatmaps)). Use SQL when none of them asks your question.

| Aspect | A built-in measurement | A SQL statement |
| --- | --- | --- |
| Result | **Frozen** under an execution key and read again by its result ID | Run afresh each time; the same statement over the same window can answer differently later |
| Sharing and saving | Saved as an [insight](/docs/investigate/saved-insights), pinned to a dashboard, sent in a [scheduled report](/docs/investigate/scheduled-reports) | None of these. Your agent can keep or pass on the returned rows |
| People | Every count opens the **people** behind it, as a selection you can save as an audience | Rows are rows. A `person_id` column is in the table, but a result is not a selection of people |
| Definition | A typed definition the platform checks and explains | Any `SELECT` you can write, inside the limits below |
| Coverage and honesty | Says when a period is unfinished or evidence is insufficient | Says nothing about it: you are reading the stored events as they are |

If a measurement can answer the question, prefer it: it is checked against the definitions of
people, sessions and periods, and its answer can be reopened as a proof page and shared as it was.

## The `events` table

A statement can read exactly one table, `events`. It holds the project's own events whose
`timestamp` falls inside the window. The organization and the project are not columns: the table holds one project.
Events that were erased or have passed their retention are not in it, and an event that was delivered
twice is one row.

| Column | Type | Meaning |
| --- | --- | --- |
| `timestamp` | `DateTime64(3)` | When the event happened, in UTC. |
| `event` | `String` | The event name. |
| `distinct_id` | `String` | The identifier the event was captured under. |
| `person_id` | `String` | The person the `distinct_id` resolves to **when the statement runs**, or an empty string when it is not resolved. A later merge of two identities changes what a later run says. |
| `session_id` | `String` | The session the event belongs to, or an empty string. |
| `environment` | `String` | The environment the event was captured in. |
| `properties` | `String` | The event's properties as **one JSON document**. Read it with the JSON functions, for example `JSONExtractString(properties, '$currency')`. Present only with the event-content permission; see [the next section](#the-properties-column-and-its-permission). |
| `groups` | `Map(String, String)` | Group type to group key, for example `groups['company']`. |
| `message_id` | `String` | The capture's own idempotency identifier. |
| `ingested_at` | `DateTime64(3)` | When the platform received the event, in UTC. |

`GET /api/v1/analytics/sql/capabilities` returns this list with the type, the description and the
permission each column needs, so a tool never has to hard-code it.

## The properties column and its permission

The properties document is the only customer content on an event, so the `properties` column exists
only for a caller who holds the event-content permission **`agents:content:read`**, and only when the
project's [content policy](/docs/manage/content-policy) allows event content to be read.

Without either, the column is **not in the table at all**. It is not a refusal and not an empty
column: every other column works, and a statement that names `properties` is refused with
`SQL_ERROR_CODE_UNKNOWN_IDENTIFIER`. Every answer says which case applied in its `properties` field:

| `properties` | Meaning |
| --- | --- |
| `SQL_PROPERTIES_DECISION_INCLUDED` | The column was in the table. |
| `SQL_PROPERTIES_DECISION_SCOPE_WITHHELD` | The caller does not currently hold `agents:content:read`. |
| `SQL_PROPERTIES_DECISION_POLICY_WITHHELD` | The project's content policy does not allow event content to be read. |
| `SQL_PROPERTIES_DECISION_UNSPECIFIED` | The statement was refused before this was decided. |

An event older than the project's content retention carries an empty string in `properties`.

## The window

Every run needs a window, and the statement sees only the events whose `timestamp` is inside it.

- The window is `[from, to)`: **`from` is included, `to` is excluded**. Both are RFC 3339 instants.
- It is at most **92 days** long, and it cannot start before the history the project can still read.
  A window that is missing, inverted, too long or outside the readable history is refused.
- One run loads at most **1,000,000 events or 256 MiB** of the window. If the window holds more, the
  run **fails** with `SQL_ERROR_CODE_SLICE_TOO_LARGE`. The input is never silently truncated, so an
  answer that comes back is computed over every event in the window. Narrow the window and run again.

The answer states the window it applied in `from` and `to`.

## Limits

| Limit | Value |
| --- | --- |
| Window | Required, at most 92 days (7,948,800 seconds) |
| Events loaded into a run | 1,000,000 events and 256 MiB; over either is `SQL_ERROR_CODE_SLICE_TOO_LARGE` |
| Rows returned | 1,000 when you do not say; at most 10,000 |
| Size of the returned rows | 8 MiB; the result is cut and `truncated` is set |
| Columns in a result | 200 |
| Statement size | 16,384 bytes |
| Time | 30 seconds of execution |
| Memory per statement | 512 MiB |
| Rows a statement may read | 20,000,000 |
| Concurrent runs | 1 per organization |
| Rate | **20 runs a minute and 300 an hour** per organization. A statement that is refused counts as a run |

`GET /api/v1/analytics/sql/capabilities` reports the current values. The rows-returned limit
applies after your statement: write your own `ORDER BY` and `LIMIT`, because the statement is run
exactly as you wrote it and nothing is added to it. If your client stops waiting, the server may
still finish its bounded run. That run still counts toward the rate limit and is still audited.

## What a statement may contain

One `SELECT`, or one `WITH ... SELECT`, over `events`, written in the SQL dialect that
`GET /api/v1/analytics/sql/capabilities` names in its `dialect` field. That includes
subqueries, non-recursive common table expressions, joins of `events` with a subquery over
`events`, window functions and every function family the dialect documents for these kinds of
value:

aggregate functions and combinators; arithmetic; arrays; comparison and logical; conditional; date
and time; hashing; JSON; maps; mathematical; rounding; string search, splitting and replacement;
tuples; type conversion; URL; UUID; window functions.

Comments are fine, and so is one trailing semicolon. Some newer syntax of the dialect may be refused
as `SQL_ERROR_CODE_SYNTAX` or `SQL_ERROR_CODE_INVALID_QUERY`; rewrite it with a plainer construct.

## What a statement may not contain

- **Anything but a single `SELECT` or `WITH ... SELECT`.** No `INSERT`, `UPDATE`, `DELETE`, `CREATE`,
  `DROP`, `ALTER`, `SET`, `SHOW`, `DESCRIBE`, `EXPLAIN` or `USE`. Nothing can be written.
- **A second statement.** Only one statement runs at a time.
- **The `SETTINGS`, `FORMAT` and `INTO OUTFILE` clauses.** Limits are fixed and results come back
  as typed rows. If `settings` or `format` is a column or an alias of yours, quote it with
  backticks.
- **Recursive common table expressions** (`WITH RECURSIVE`).
- **Any table other than `events`**, including system tables, other projects and other organizations.
  A statement can reach nothing but its own project's events inside its own window.
- **Table functions that read from outside the statement**, such as `url`, `file`, `s3`, `remote`,
  `cluster`, `mysql`, `dictionary` and `merge`, and the rest of that family.
- **Dictionary and join lookups**: `dictGet*`, `dictHas*`, `joinGet*`.
- **Functions that report on the server or the session**, such as `hostName`, `version`,
  `currentUser`, `currentDatabase`, `uptime` and `getSetting`.
- **`sleep` and `sleepEachRow`.**

These functions are refused however the call is written: with the name in backticks or double
quotes, after `APPLY`, or with any kind of space around it. A function name written in quotes may
not contain a backslash. Quoting is still the way to name a column or an alias that shares a
function's or a keyword's name — a quoted name is refused only where it is called.

## Refusals and their remedies

A statement that is refused or fails is a **complete answer**, not an HTTP error: the response is
`200` with an `error` object (`code`, `message` and `position`) and empty `columns` and `rows`. The
`message` is a sentence the platform wrote and is safe to show as it is. Only a syntax error carries
a `position`: the 1-based character position where the statement stopped making sense.

| `error.code` | When | What to do |
| --- | --- | --- |
| `SQL_ERROR_CODE_NOT_CONFIGURED` | SQL is not enabled on this deployment. Nothing ran. | Ask whoever operates the deployment to enable it. `GET /api/v1/analytics/sql/capabilities` answers `available: false` in the same case. |
| `SQL_ERROR_CODE_STATEMENT_SIZE` | The statement is empty or larger than 16,384 bytes. | Send a statement; shorten it. Size is counted in bytes, not characters. |
| `SQL_ERROR_CODE_NOT_A_SELECT` | It is not a single `SELECT` or `WITH ... SELECT`, or it is not valid UTF-8 text. | Run a `SELECT`. |
| `SQL_ERROR_CODE_MULTIPLE_STATEMENTS` | Something follows the first statement. | Send one statement at a time. |
| `SQL_ERROR_CODE_FORBIDDEN_CLAUSE` | `SETTINGS`, `FORMAT`, `INTO OUTFILE` or a recursive common table expression. | Remove the clause; quote a column named like a keyword with backticks. |
| `SQL_ERROR_CODE_FORBIDDEN_FUNCTION` | A function or table function from the list above. The message names it. | Compute the value from the columns of `events` instead. |
| `SQL_ERROR_CODE_SYNTAX` | The statement could not be parsed. `position` locates the fault, and the message says what was expected there. | Fix the statement at that position. |
| `SQL_ERROR_CODE_UNKNOWN_IDENTIFIER` | A column, table or function does not exist here. | Use only the ten columns above. `properties` exists only with `agents:content:read` and a policy that allows it. |
| `SQL_ERROR_CODE_ACCESS_DENIED` | The statement reaches for something other than `events`, or tries to change a fixed limit. | Read `events` only and leave the limits alone. |
| `SQL_ERROR_CODE_INVALID_QUERY` | The statement parses but is not valid: wrong types, wrong arguments, a misused aggregate. The message ends with the engine's numeric error code. | Check the types and arguments of each function. |
| `SQL_ERROR_CODE_WINDOW` | The window is missing, inverted, longer than 92 days or outside the readable history. | Choose a valid window. |
| `SQL_ERROR_CODE_SLICE_TOO_LARGE` | The window holds more events than one run may load. | Narrow the window. |
| `SQL_ERROR_CODE_TIMEOUT` | The statement ran longer than 30 seconds. | Narrow the window, filter earlier, or return aggregates. |
| `SQL_ERROR_CODE_MEMORY_LIMIT` | The statement needed more than the memory limit. | Narrow the window or group by less. Exact distinct counts and large sorts need the most. |
| `SQL_ERROR_CODE_READ_LIMIT` | The statement would read more than 20,000,000 rows. | Filter earlier, or avoid reading the table several times. |
| `SQL_ERROR_CODE_RESULT_SHAPE` | The result has more than 200 columns, a single row over the size limit, or a column type that cannot be returned. | Select fewer columns, or convert the column, for example with `toString`. |
| `SQL_ERROR_CODE_BUSY` | Another run of your organization is still in progress — one runs at a time — or the service is at capacity. Nothing is wrong with the statement. | Retry in a moment. |
| `SQL_ERROR_CODE_RATE_LIMITED` | The organization's run limit was reached or could not be checked. Nothing about the statement was looked at. | Retry later. |
| `SQL_ERROR_CODE_STORAGE_EXHAUSTED` | The analytics store is below its free-space floor. Retrying cannot help. | Contact whoever operates the deployment. |
| `SQL_ERROR_CODE_UNAVAILABLE` | The run could not complete for a reason that is not the statement's. | Retry. If it persists, contact support. |

Only authentication, authorization and a malformed request are HTTP errors. They are described under
[REST](#rest).

## What your agent gets back

A successful answer carries these fields, and a refused one carries the same envelope with `error`
set. The answer has no `url` or link field, because SQL has no proof page.

| Field | Meaning |
| --- | --- |
| `columns` | `[{"name", "type"}]`: the name and the **type** of every result column. The type is what tells you how to read a value. |
| `rows` | `[{"values": [...]}]`: one entry per row, one value per column, in column order. |
| `truncated` | `true` when the result was cut at the row limit or the 8 MiB size limit. |
| `statistics` | `slice_rows`, `slice_bytes`, `rows_read`, `result_rows`, `result_bytes`, `elapsed_ms`; see below. |
| `error` | `null` for a result; otherwise `{"code", "message", "position"}`. |
| `properties` | Whether the `properties` column existed; see above. |
| `from`, `to` | The window that was applied. |
| `execution_id` | Identifies this run in the audit log. |

### How values are encoded

Render a value by its column's `type`, and never coerce a decimal string into a float.

| Column type | Value in `rows[].values` |
| --- | --- |
| `NULL` (any `Nullable(...)` type) | `null` |
| `Bool` | `true` or `false` |
| `Int8` to `Int32`, `UInt8` to `UInt32` | a JSON number |
| `Float32`, `Float64` | a JSON number; `NaN`, `Infinity` and `-Infinity` arrive as those **strings** |
| `Int64`, `UInt64` and wider, `Decimal(...)` | a **decimal string** such as `"114"` or `"19.9899"`, exact in every digit |
| `String`, `FixedString`, `Enum`, `UUID`, `IPv4`, `IPv6` | a string; invalid UTF-8 is replaced by U+FFFD |
| `Date`, `Date32` | `"2026-10-04"` |
| `DateTime`, `DateTime64(n)` | an RFC 3339 string in UTC with the column's precision, such as `"2026-10-03T22:31:12.259Z"` |
| `Array`, `Tuple` | a list |
| `Map` with string keys | an object |
| `Map` with other keys | a list of `[key, value]` pairs |

Counts such as `count()` are `UInt64`, so they arrive as strings. A type with no such form (an
aggregate state) is refused with `SQL_ERROR_CODE_RESULT_SHAPE`; convert it first.

### Statistics

| Field | Meaning |
| --- | --- |
| `slice_rows` | Events loaded into the `events` table for this run, from the window |
| `slice_bytes` | The size of those events |
| `rows_read` | Rows your statement read |
| `result_rows` | Rows returned |
| `result_bytes` | Size of the encoded rows |
| `elapsed_ms` | Wall time of the whole run, in milliseconds |

All six are decimal strings.

### Truncation

When `truncated` is `true` the result was cut after `result_rows` rows. Narrow the statement, add
an aggregate or a `WHERE`, or raise `limit` up to 10,000. A statement that needs more rows than
that should aggregate. A **single row** larger than 8 MiB cannot be cut; it is
`SQL_ERROR_CODE_RESULT_SHAPE`. Keeping a truncated result keeps the returned rows only, never the
full result.

## Examples

Replace the event names with yours. All of them run verbatim.

### Events per day

```sql
SELECT toDate(timestamp) AS day, count() AS events
FROM events
GROUP BY day
ORDER BY day
```

One row per day: `day` (`Date`), `events` (`UInt64`).

```json
{"columns": [{"name": "day", "type": "Date"}, {"name": "events", "type": "UInt64"}],
 "rows": [{"values": ["2026-10-02", "4821"]}, {"values": ["2026-10-03", "5107"]}]}
```

### Top events

```sql
SELECT event, count() AS events, uniqExact(distinct_id) AS identities
FROM events
GROUP BY event
ORDER BY events DESC, event
LIMIT 20
```

Up to 20 rows: `event` (`String`), `events` (`UInt64`), `identities` (`UInt64`).

### Distinct people per event

```sql
SELECT
    event,
    uniqExactIf(person_id, person_id != '') AS people,
    countIf(person_id = '') AS events_without_a_person
FROM events
GROUP BY event
ORDER BY people DESC, event
LIMIT 20
```

Up to 20 rows: `event` (`String`), `people` (`UInt64`), `events_without_a_person` (`UInt64`). An
event whose identity is not resolved to a person has an empty `person_id`; this statement counts
those separately instead of counting them as one person.

### Count by a property value

Needs the `properties` column, so it needs `agents:content:read`.

```sql
SELECT
    JSONExtractString(properties, '$currency') AS currency,
    count() AS events
FROM events
WHERE JSONHas(properties, '$currency')
GROUP BY currency
ORDER BY events DESC, currency
```

One row per value: `currency` (`String`), `events` (`UInt64`). Values are case sensitive, so `USD`
and `usd` are two rows.

### Two-step conversion by person

How many people did a first event, and how many of those did a second event afterwards:

```sql
SELECT
    countIf(first_events > 0) AS reached_step_1,
    countIf(first_events > 0 AND last_second > first_at) AS reached_step_2
FROM (
    SELECT
        person_id,
        countIf(event = '$pageview') AS first_events,
        minIf(timestamp, event = '$pageview') AS first_at,
        maxIf(timestamp, event = '$pageleave') AS last_second
    FROM events
    WHERE person_id != ''
    GROUP BY person_id
)
```

One row: `reached_step_1` (`UInt64`), `reached_step_2` (`UInt64`). It counts people whose identity
resolves to a person, and it counts a person as converted when they did the second event at any time after the first
time they did the first. For a conversion with a time limit, ordered steps, or the people behind the numbers, use a
[funnel](/docs/investigate/product-analytics#measure-an-ordered-person-or-account-funnel).

## Run a statement through the CLI, MCP or REST

Running a statement needs three permissions: **`analytics:sql`**, **`analytics:read`** and
**`persons:read`**. Reading the capabilities needs only `analytics:read`.

### CLI

```bash
anectico --project PROJECT_UUID analytics sql capabilities

anectico --project PROJECT_UUID analytics sql run \
  --from 2026-10-01T00:00:00Z --to 2026-10-08T00:00:00Z \
  --limit 100 \
  --statement "SELECT event, count() AS events FROM events GROUP BY event ORDER BY events DESC LIMIT 10"
```

Use `--file statement.sql`, or `--file -` for standard input, instead of `--statement`. The command
prints the same envelope as REST, and **exits non-zero** after printing it when the statement was
refused or failed, so a script can tell. `--limit 0` or no `--limit` uses the default of 1,000 rows.

### MCP

Both tools are read actions, reached with `execute_read_action`; list them with `list_read_actions`.
Running needs `mcp:read` as well as the three permissions above.

```json
{"action": "get_analytics_sql_capabilities", "arguments": {}}
```

```json
{"action": "execute_analytics_sql", "arguments": {
  "project_id": "PROJECT_UUID",
  "statement": "SELECT event, count() AS events FROM events GROUP BY event ORDER BY events DESC LIMIT 10",
  "from": "2026-10-01T00:00:00Z",
  "to": "2026-10-08T00:00:00Z",
  "limit": 100
}}
```

MCP returns **100 rows when you do not say and at most 1,000**, because a model reads every row it
is given. The rows come back as JSON in `result_json` inside untrusted delimiters: they are your
events' own text, never instructions. Remove only the outer delimiters and decode the JSON. A
refused statement is a normal answer with `error_code`, `error_message` and `error_position`.

### REST

```bash
curl --fail-with-body \
  -H "X-Anectico-API-Key: $ANECTICO_API_KEY" \
  https://app.anectico.com/api/v1/analytics/sql/capabilities
```

```bash
curl --fail-with-body \
  -H "X-Anectico-API-Key: $ANECTICO_API_KEY" \
  -H "Content-Type: application/json" \
  https://app.anectico.com/api/v1/analytics/sql \
  -d '{
    "project_id": "PROJECT_UUID",
    "statement": "SELECT JSONExtractString(properties, '"'"'$currency'"'"') AS c, count() FROM events GROUP BY c ORDER BY c",
    "from": "2026-10-02T09:00:00Z",
    "to": "2026-10-04T09:00:00Z",
    "limit": 1000
  }'
```

A project-bound key may leave out `project_id`. The capabilities route takes **no query
parameters** and answers `400` if given any. A real answer to the statement above, with the
`properties` column available:

```json
{
  "error": null,
  "columns": [{"name": "c", "type": "String"}, {"name": "count()", "type": "UInt64"}],
  "rows": [{"values": ["EUR", "1"]}, {"values": ["USD", "14"]}, {"values": ["usd", "1"]}],
  "truncated": false,
  "statistics": {"slice_rows": "79", "slice_bytes": "38960", "rows_read": "79",
                 "result_rows": "3", "result_bytes": "37", "elapsed_ms": "41"},
  "properties": "SQL_PROPERTIES_DECISION_INCLUDED",
  "from": "2026-10-02T09:05:04.631Z",
  "to": "2026-10-04T09:05:04.631Z",
  "execution_id": "28de3503-fe5e-4089-aeb9-f9f27f6a78e4"
}
```

A statement the server refused is the same envelope with an `error`, `200` and empty `columns` and
`rows`:

```json
{
  "error": {
    "code": "SQL_ERROR_CODE_ACCESS_DENIED",
    "message": "the statement reaches for something other than the `events` table, or changes a fixed limit; that is not available",
    "position": 0
  },
  "columns": [], "rows": [], "truncated": false,
  "properties": "SQL_PROPERTIES_DECISION_INCLUDED",
  "execution_id": "53f9c1d3-87e9-47f2-9320-142570540528"
}
```

| Status | When |
| --- | --- |
| `200` | A result, or a refused or failed statement with an `error` |
| `400` | The window is missing or invalid, the body is malformed or has an unknown field, or the capabilities route was given a query parameter |
| `401` | The credential is missing or not valid |
| `403` | The credential lacks a permission: `{"error": "PermissionDenied", "message": "..."}` names it |
| `429` | The organization's rate limit was reached: `{"error": "rate_limited"}`. Wait and retry |

A run can take up to about a minute and a half before a `SQL_ERROR_CODE_TIMEOUT` answer arrives, so
give the HTTP client at least two minutes.

## Permissions

| Permission | What it does here |
| --- | --- |
| `analytics:sql` | Run a statement. Granted to members, developers, administrators and owners by default. **Not** granted to viewers, to agents connected over OAuth, or to Live screen publishers. An API key can carry it only if its creator holds it. |
| `analytics:read` | Required to run, and the only permission needed to read the table description. |
| `persons:read` | Required to run: the `person_id` column is a resolved identity. |
| `agents:content:read` | Makes the `properties` column part of your table, when the project's content policy allows event content to be read. Without it everything else still works. |

`analytics:sql` grants no data that `analytics:read` does not already disclose. It grants your own
computation over it, bounded by the limits above. See [Permission scopes](/docs/reference/permissions)
for the full catalog.

## Every run is audited

Each run the rate limit admits writes one entry to the organization's audit log, whether it returned
rows, was refused or failed, and whichever way it was started: the CLI, MCP or REST.
A request refused by the rate limit is not a run: nothing about it is looked at, and it writes no
entry. The audit log therefore gains at most 20 SQL entries a minute and 300 an hour. In the
Console, open **Audit log** (`/audit-log`) to read the entries; see
[the Console guide](/docs/manage/console#audit-log). The entry records the project, the `execution_id`, a digest of the
statement exactly as sent, the statement itself shortened to 120 characters with sensitive text
redacted, the window, the outcome, the rows loaded and returned, whether the result was truncated
and the time taken. A result is not returned for a run whose audit entry could not be written.

## What SQL does not do

- **No other tables.** There is no table of people and their profiles, accounts, sessions or
  technical telemetry such as logs, traces and metrics. Sessions are only the `session_id` column.
- **No joins to anything but `events` itself.** You can join `events` to a subquery over `events`.
- **No saved queries and no scheduled SQL.** Keep a statement in your own repository or notes; run it
  again with the CLI or REST when you need it.
- **No writing.** A statement cannot change or delete events or anything else.
- **No queries across projects or organizations.** One run reads one project.
- **No saved insights, dashboard widgets, audiences or alerts from a result.** For those, use the
  [built-in measurements](/docs/investigate/product-analytics), which are frozen and shareable and
  carry the people behind every count.
- **No unfinished-period or coverage warnings.** SQL reads whatever the window holds.

## Next steps

- For a question a measurement can answer, start from [product analytics](/docs/investigate/product-analytics).
- To take your events out of Anectico on a schedule instead, use [warehouse export](/docs/manage/warehouse-export).
