How can I find the error code thrown in SQL Server? -

-

i have code:

if (@@rowcount != 1)     throw 50004,'mark_test - problem setting test status marked',1

i know can error message this:

set @errormessage = error_message()

but how can number 50004 ?

use error_number function

returns error number of error caused catch block of try…catch construct run.

demo

begin try     select 1     union     select 1      if ( @@rowcount != 1 )       throw 50004, 'mark_test - problem setting test status marked', 1 end try  begin catch     select error_number=error_number(),            error_message=error_message() end catch

result

error_number    error_message 50004           mark_test - problem setting test status marked
