Versions of Open Client prior to 12.5 had a limit of 255 bytes per column for character or binary columns stored in CS_CHAR and CS_BINARY host datatypes. If you use versions of Open Client earlier than version 12.5 with Adaptive Server version 12.5, the wider rows of the result set may be truncated.
Adaptive Server version 12.5 and later can store data that has different limits than data stored in pre-12.5 versions of ASE. Clients also must be able to handle the new limits the data can use. Open Client version 12.5 and later supports Adaptive Server 12.5 and later limits. If you are using pre-12.5 versions of Open Client, they cannot process the data if you:
Upgrade to Adaptive Server version 12.5 or later
Drop and re-create the tables with wide columns
Insert wide data
Versions of Open Client earlier than 12.5 work successfully with Adaptive Server version 12.5 or later, if you do not use the new limits (such as wider columns and rows, larger logical page sizes, and so on).
