InsertQuery_mysql::execute

public function InsertQuery_mysql::execute

public InsertQuery_mysql::execute()

Executes the insert query.

Return value

The last insert ID of the query, if one exists. If the query was given multiple sets of values to insert, the return value is undefined. If no fields are specified, this method will do nothing and return NULL. That makes it safe to use in multi-insert loops.
