* Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.
* As a convention, on RDBMS brands that support sequences
* (e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence
* from the arguments and returns the last id generated by that sequence.
* On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method
* returns the last value generated for such a column, and the table name
* argument is disregarded.
* The IDENTITY_VAL_LOCAL() function gives the last generated identity value
* in the current process, even if it was for a GENERATED column.
* @param string $tableName OPTIONAL
* @param string $primaryKey OPTIONAL
* @throws Doctrine_Adapter_Db2_Exception
