You Asked

In Microsoft SQL Server we are strongly encouraged to NOT use the MERGE statement due to unreliability.
Is the same true for the Oracle MERGE statement?
Is it reliable?

Thanks,

100% rock solid.

Any incorrect behaviour for MERGE is a bug and we'd fix it.

People sometimes confuse an error ORA-30926 that might come out of MERGE with reliability, but that error only comes when your input data doesn't make sense. See the video below for details
