The <function>maxdb_insert_id</function> 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.

&reftitle.returnvalues;

The value of the <literal>DEFAULT SERIAL</literal> 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 <literal>DEFAULT_SERIAL</literal>
|

value.
