The directive @alias provides an alternative name to the table on which the field is specified.

This directive has one argument: AS in which you can provide the alternative name for the field.

SELECT JSON_SERIALIZE(data PRETTY) AS data FROM GRAPHQL('
    driver @alias(as: drv) {
        id: driver_id
        name
        drv.points
        teamName @generated(sql: "select name from team where team.team_id = drv.team_id")
    }
');

The example provides an alternative name to the driver field as drv using the @alias directive. So in this example, drv.team_id would produce identical results as using driver.team_id without using the @alias directive:
