Hi Mark;
Thanks for the RPC example ... another good way to communicate with SP's!
I just wanted to point out to the novice DB crowd - that you can use the "timestamp timestamp" column declaration in MS-SS with no ill effect. However, if you declare a column as "timestamp timestamp" in ASE (using the column name of the same) then the DBMS will use this for "TimeStamp Locking" and not what your application intended it for. MS-SS does not support the TSL feature as Bill Gates had it removed after Sybase ported the SQLServer code over to MS for them. Good move Bill - Duh ... LOL!
BTW: the DW understands TS Locking when talking to ASE!
