Re: SQL: using CASE, LIKE, and a variable

Are you creating a DS with a percent sign, the string, then the
percent sign?  One solution might be to code a %Trim operation with
the token, and the percent signs together, ex.

LikePhrase = '%' + %Trim(SearchArg) & '%';

If you make LikePhrase a VARYING alpha variable, it should eliminate
the spaces.  I am not familiar with the way RPG passes the var to SQL,
but for anything else, this would work.
