Subj:   Re: Case statements
 
From:   Geoffrey Rommel

  We regularly use CASE statements in our code as they are excellent in that only one pass of a table is required to satisfy a query.  



This is a small point, but everyone should be aware that these are CASE expressions, not statements. 'x' is an expression; 'y = x + 5' is a statement. Similarly, SELECT is a statement; CASE ... END is an expression within the statement.

I mention this because V2R4.1 will have a CASE statement (only within stored procedures, I think), so it may become important to keep this distinction in mind.
