Is it possible in Sybase to set global variable @@error = 0 for successfull return after raiserror statement?
raiserror 'Test';
set @@error = 0;
回答1:
In Sybase ASE you can't directly set @@error or use raiseerror with a string.
Use sp_addmessage to add custom error numbers and messages to your database. Once the error is listed, you can then reference it using the raiserror error_#
Sybase ASE reserves error numbers 20,000 and below for system use, so user defined errors can start at 20,001
More detailed information on raiserror can be found in the documentation.
