## About
A `mysql-sql` tool executes a pre-defined SQL statement against a MySQL
database. It's compatible with any of the following sources:
- [cloud-sql-mysql](../../sources/cloud-sql-mysql.md)
- [mysql](../../sources/mysql.md)
The specified SQL statement is executed as a [prepared statement][mysql-prepare],
and expects parameters in the SQL query to be in the form of placeholders `?`.
[mysql-prepare]: https://dev.mysql.com/doc/refman/8.4/en/sql-prepared-statements.html
## 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_flights_by_number:
kind: mysql-sql
source: my-mysql-instance
statement: |
SELECT * FROM flights
WHERE airline = ?
AND flight_number = ?
LIMIT 10
description: |
Use this tool to get information for a specific flight.
Takes an airline code and flight number and returns info on the flight.
Do NOT use this tool with a flight id. Do NOT guess an airline code or flight number.
A airline code is a code for an airline service consisting of two-character
airline designator and followed by flight number, which is 1 to 4 digit number.
For example, if given CY 0123, the airline is "CY", and flight_number is "123".
Another example for this is DL 1234, the airline is "DL", and flight_number is "1234".
If the tool returns more than one option choose the date closes to today.
Example:
{{
"airline": "CY",
"flight_number": "888",
}}
Example:
{{
"airline": "DL",
"flight_number": "1234",
}}
parameters:
- name: airline
type: string
description: Airline unique 2 letter identifier
- name: flight_number
type: string
description: 1 to 4 digit number
```
### 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
tools:
list_table:
kind: mysql-sql
source: my-mysql-instance
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
```
