MERGE 2 INTO target_table tgt 3 USING source_table src 4 ON ( src.object_id = tgt.object_id ) 5 WHEN MATCHED 6 THEN 7 UPDATE 8 SET tgt.object_name = src.object_name 9 , tgt.object_type = src.object_type 10 WHEN NOT MATCHED 11 THEN 12 INSERT ( tgt.object_id 13 , tgt.object_name 14 , tgt.object_type ) 15 VALUES ( src.object_id 16 , src.object_name 17 , src.object_type ); We will now run a bulk update and insert as separate SQL statements.The update is written as an updateable in-line view which is often the fastest technique for bulk updating one table from another.In the following example, we'll remove the primary key from the source table and duplicate some source data.We will revert to the key-preserved join and this time our MERGE should be successful.This article introduces the new MERGE SQL command (sometimes referred to as "UPSERT").MERGE is a DML command that enables us to optionally update or insert data into a target table, depending on whether matching records already exist.
We will start by creating the source table as a selection of ALL_OBJECTS data. In the following example, we will merge the source table into the target table.It has been raised because Oracle found more than one target row that matched a single source row.
