Question

I’m building a complex SQL query and I want to test a result in a while statement.

I want to do something like:

WHERE ( R.Expired IS NULL OR R.Expired > SYSDATE )
  AND (
    CASE
      WHEN R.Description LIKE '%SSX%' THEN TRUE
      ELSE  FALSE
    END
  ) ORDER BY R.Name

But PL/SQL says it has some “invalid relational operator” (translated).

Is there something wrong with my CASE statement?

Answer 1

The CASE WHEN stuff looks unnecessary to me.

Just use

AND (R.Description Like '%SSX')

First rule of debugging – avoid unnecessary complexities.
