Is it possible to execute an optimized merge with multiple columns in on clause where the target table has a composite key?
Something similar to
MERGE INTO table1 t1 USING table2 t2 on (t1.col1 = t2.col1 and t1.col2 = t2.col2)
WHEN MATCHED THEN UPDATE SET col1 = t2.col1, col2 = t2.col2
where t1 has a primary key defined as CONSTRAINT composite_pk PRIMARY KEY (col1, col2)
