## About

A `firebird-sql` tool executes a pre-defined SQL statement against a Firebird
database. It's compatible with the following source:

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

The specified SQL statement is executed as a [prepared statement][fb-prepare],
and supports both positional parameters (`?`) and named parameters (`:param_name`).
Parameters will be inserted according to their position or name. If template
parameters are included, they will be resolved before the execution of the
prepared statement.

[fb-prepare]: https://firebirdsql.org/refdocs/langrefupd25-psql-execstat.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: firebird-sql
    source: my_firebird_db
    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 Named Parameters

```yaml
tools:
  search_flights_by_airline:
    kind: firebird-sql
    source: my_firebird_db
    statement: |
      SELECT * FROM flights
      WHERE airline = :airline
      AND departure_date >= :start_date
      AND departure_date <= :end_date
      ORDER BY departure_date
    description: |
      Search for flights by airline within a date range using named parameters.
    parameters:
      - name: airline
        type: string
        description: Airline unique 2 letter identifier
      - name: start_date
        type: string
        description: Start date in YYYY-MM-DD format
      - name: end_date
        type: string
        description: End 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](../#template-parameters).

```yaml
tools:
  list_table:
    kind: firebird-sql
    source: my_firebird_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
```
