Solution 2

On the first look: CASE WHEN statement is incomplete. Must be ended with END word! In both cases!

Have a look here: CASE (SQL)[^]

Solution 1

For starters, I suspect the first error is caused by:

SELECT CASE when mytable='CertUserToAccount' then CertUserToAccount

as indicated by Error on line 13.

The 'SELECT' statement is aliased to 't', but where is it selecting anything from?
