## About
A `bigquery-execute-sql` tool executes a SQL statement against BigQuery.
It's compatible with the following sources:
- [bigquery](../../sources/bigquery.md)
`bigquery-execute-sql` accepts the following parameters:
- **`sql`** (required): The GoogleSQL statement to execute.
- **`dry_run`** (optional): If set to `true`, the query is validated but not run,
returning information about the execution instead. Defaults to `false`.
The tool's behavior is influenced by the `allowedDatasets` restriction on the
`bigquery` source:
- **Without `allowedDatasets` restriction:** The tool can execute any valid GoogleSQL
query.
- **With `allowedDatasets` restriction:** Before execution, the tool performs a dry run
to analyze the query.
It will reject the query if it attempts to access any table outside the
allowed `datasets` list. To enforce this restriction, the following operations
are also disallowed:
- **Dataset-level operations** (e.g., `CREATE SCHEMA`, `ALTER SCHEMA`).
- **Unanalyzable operations** where the accessed tables cannot be determined
statically (e.g., `EXECUTE IMMEDIATE`, `CREATE PROCEDURE`, `CALL`).
## Example
```yaml
tools:
execute_sql_tool:
kind: bigquery-execute-sql
source: my-bigquery-source
description: Use this tool to execute sql statement.
