The <span class="function"><strong>cubrid_insert_id()</strong></span> function retrieves the ID

generated for the AUTO_INCREMENT column which is updated by the previous

INSERT query. It returns 0 if the previous query does not generate new

CUBRID supports AUTO_INCREMENT for more than one columns in a table. In
|
|
most cases, there will be a single AUTO_INCREMENT column in a table. If
|
|
there are multiple AUTO_INCREMENT columns, this function should not be
|
|
used even if it will return a value.
