spanner-sql docs 1 A "spanner-sql" tool executes a pre-defined SQL statement against a Google Cloud Spanner database.

About

A spanner-sql tool executes a pre-defined SQL statement (either googlesql or postgresql) against a Cloud Spanner database. It's compatible with any of the following sources:

GoogleSQL

For the googlesql dialect, the specified SQL statement is executed as a data manipulation language (DML) statements, and specified parameters will inserted according to their name: e.g. @name.

PostgreSQL

For the postgresql dialect, the specified SQL statement is executed as a prepared statement, and specified parameters will inserted according to their position: e.g. $1 will be the first parameter specified, $@ will be the second parameter, and so on.

Example

{{< tabpane persist="header" >}} {{< tab header="GoogleSQL" lang="yaml" >}}

tools: search_flights_by_number: kind: spanner-sql source: my-spanner-instance statement: | SELECT * FROM flights WHERE airline = @airline AND flight_number = @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
