## About

A `sqlite-sql` tool executes SQL statements against a SQLite database.
It's compatible with any of the following sources:

- [sqlite](../../sources/sqlite.md)

SQLite uses the `?` placeholder for parameters in SQL statements. Parameters are
bound in the order they are provided.

The statement field supports any valid SQLite SQL statement, including `SELECT`,
`INSERT`, `UPDATE`, `DELETE`, `CREATE/ALTER/DROP` table statements, and other
DDL statements.

### Example

> **Note:** This tool uses parameterized queries to prevent SQL injections.
> Query parameters can be used as substitutes for arbitrary expressions.
> Parameters cannot be used as substitutes for identifiers, column names, table
> names, or other parts of the query.

```yaml
kind: tools
name: search-users
type: sqlite-sql
source: my-sqlite-db
description: Search users by name and age
parameters:
  - name: name
    type: string
    description: The name to search for
  - name: min_age
    type: integer
    description: Minimum age
statement: SELECT * FROM users WHERE name LIKE ? AND age >= ?
```

### Example with Template Parameters

> **Note:** This tool allows direct modifications to the SQL statement,
> including identifiers, column names, and table names. **This makes it more
> vulnerable to SQL injections**. Using basic parameters only (see above) is
> recommended for performance and safety reasons. For more details, please check
> [templateParameters](..#template-parameters).

```yaml
kind: tools
name: list_table
type: sqlite-sql
source: my-sqlite-db
statement: |
  SELECT * FROM {{.tableName}};
description: |
  Use this tool to list all information from a specific table.
  Example:
  {{
      "tableName": "flights",
  }}
templateParameters:
  - name: tableName
    type: string
    description: Table to select from
```
