Allo,
 
I've hit a bit of a snag. I need to group a report on a formula field, but it takes a mortifyingly long time to run...
 
So, I thought I'd try to recreate the formula in SQL, to take advantage of server-side grouping.
 
The original formula looked rather like this:
 
if {table.myfield} in ["a","b","c"] then "Group One" else
if {table.myfield} in ["X","Y","Z"] then "Group Two" else "Error"
 
Can I reproduce this in an SQL expression? I can't seem to find a way of making a list...
 
Cheers!

if you are using a stored proc, it would be simple.  I will be honest, I don't know how to do it in CR.  If the back end is SQL server, you probably want to add something like:
 CASE WHEN {table.field} in ('a','b','c') THEN 'Group 1'
 CASE WHEN {table.field} in ('x','y','z') THEN 'Group 2'
 ELSE 'Error' END AS GroupingField
