#
lastInsertId( string $tableName = null, string $primaryKey = null )
Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT
column.
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.
Oracle does not support IDENTITY columns, so if the sequence is not
specified, this method returns null.
