Expressions returning binary or character datum can be up to 16384 bytes in length. However, earlier versions of Adaptive Server only allowed expressions to be up to 255 bytes in length. If you have upgraded from an earlier release of Adaptive Server, and your stored procedures or scripts store a result string of up to 255 bytes, the remainder will be truncated. You may have to re-write these stored procedures and scripts for to account for the additional length of the expressions.
