trino-sql
About
A trino-sql
tool executes a pre-defined SQL statement against a Trino
database. It’s compatible with any of the following sources:
The specified SQL statement is executed as a prepared statement,
and specified parameters will be inserted according to their position: e.g. $1
will be the first parameter specified, $2
will be the second parameter, and so
on. If template parameters are included, they will be resolved before execution
of the prepared statement.
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.
tools:
search_orders_by_region:
kind: trino-sql
source: my-trino-instance
statement: |
SELECT * FROM hive.sales.orders
WHERE region = $1
AND order_date >= DATE($2)
LIMIT 10
description: |
Use this tool to get information for orders in a specific region.
Takes a region code and date and returns info on the orders.
Do NOT use this tool with an order id. Do NOT guess a region code or date.
A region code is a code for a geographic region consisting of two-character
region designator and followed by optional subregion.
For example, if given US-WEST, the region is "US-WEST".
Another example for this is EU-CENTRAL, the region is "EU-CENTRAL".
If the tool returns more than one option choose the date closest to today.
Example:
{{
"region": "US-WEST",
"order_date": "2024-01-01",
}}
Example:
{{
"region": "EU-CENTRAL",
"order_date": "2024-01-15",
}}
parameters:
- name: region
type: string
description: Region unique identifier
- name: order_date
type: string
description: Order date in YYYY-MM-DD format
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.
