The maxdb_insert_id() function returns the ID generated by a query on a table with a column having the DEFAULT SERIAL attribute. If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the DEFAULT SERIAL attribute, this function will return zero.
The value of the DEFAULT SERIAL field that was updated by the previous query. Returns zero if there was no previous query on the connection or if the query did not update an DEFAULT_SERIAL value.
Note:
If the number is greater than maximal int value, maxdb_insert_id() will return a string.
