Function SCOPE_IDENTITY not found
The SCOPE_IDENTITY function is not available in Sybase ASE as it is specific to Microsoft Sql Server. If you want to obtain the last identity value that was generated you can use the @@IDENTITY global variable like so:

insert into sales_daily (syb_identity, stor_id) 
     values (102, "1349")
select @@identity


You can find the documentation for the @@IDENTITY global variable at SyBooks Online.
