## About
A `couchbase-sql` tool executes a pre-defined SQL statement against a Couchbase
database. It's compatible with any of the following sources:
- [couchbase](../../sources/couchbase.md)
The specified SQL statement is executed as a parameterized statement, and specified
parameters will be used according to their name: e.g. `$id`.
## 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
tools:
search_products_by_category:
kind: couchbase-sql
source: my-couchbase-instance
statement: |
SELECT p.name, p.price, p.description
FROM products p
WHERE p.category = $category AND p.price < $max_price
ORDER BY p.price DESC
LIMIT 10
description: |
Use this tool to get a list of products for a specific category under a maximum price.
Takes a category name, e.g. "Electronics" and a maximum price e.g 500 and returns a list of product names, prices, and descriptions.
Do NOT use this tool with invalid category names. Do NOT guess a category name, Do NOT guess a price.
Example:
{{
"category": "Electronics",
"max_price": 500
}}
Example:
{{
"category": "Furniture",
"max_price": 1000
}}
parameters:
- name: category
type: string
description: Product category name
- name: max_price
type: integer
description: Maximum price (positive integer)
```
### 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).
