# querySQL

Canonical ID: `data.query`.

```text
querySQL(sql, parameters)
```

Returns a list of maps with unique column names as keys. Use positional ? parameters. Maximum 1000 rows and 1 MiB; BLOBs and integers outside the exact 53-bit range are unsupported. Requires SQLite access.

Returns a Map with `ok`, `status`, `value` and `error`. Check `ok` before using `value`; denial or an unavailable host is a structured failure.

Requires Creator Pro or its technical trial for IDE/CLI run and build. Available on desktop, CLI and supported native exports; not in the public playground. Source remains editable in Learner. Generated apps have no Pliro licence check.

## Call example

See the [advanced application guide](../guides/advanced-applications.md) for declarations, explicit host permissions and complete examples. This call assumes the required permissions; `handle` means the `value` from a successful open operation.

```text
querySQL("SELECT ? AS answer", [42])
```
