Trax_ID function
AdaBase.Driver.Base.[DB].last_insert_id ()

This function returns the ID of the last inserted row. If the driver does not support the concept of auto-increment fields, the return value will always be zero.

For the PostgreSQL driver, if the query is in the form of INSERT INTO .. RETURNING, then the last_insert_id comes directly from the result set of this INSERT statement. If no RETURNING clause is present, the last_insert_id is the result of "SELECT lastval()" which is normally accurate, but not in every case.

See custom loggers for a usage example.

[DB] is "MySQL.MySQL_Driver", "PostgreSQL.PostgreSQL_Driver", or "SQLite.SQLite_Driver"
