Review comment:
makes sense...original test was only checking for the compilation error
I don't think we have this covered that well..so I've added the `select` statements

Review comment:
no; the issue was a compilation - I didn't wanted to add a big explain which doesn't catch any part of the issue

Review comment:
my original test case only had one case; later added a second
removed these `drop` statements as they are only needed from beeline

Do we have tests that checks the content of the target table after merge like `select * from t1` ?
