I am building an application with PB V6.5 and Sybase V11.5. I a using the PFC and supplying all of the IUD logic to the SQL Preview event via the Stored Procedure Utility. I need to compare timestamps in my update procedures; however, PowerBuilder has no concept of Varbinary. I can pass the timestamp down as a string but when it comes time to pass the timestamp back up to the update proc I'm at a loss as to how to get it back to its original varbinary format. Converting it on the client and passing it back is not an option. Any ideas?
