sql server - sql raiseerror error.number wrong in VB -

-

i wrote t-sql query includes test valid employeeno. if employeeno not valid, following:

raiserror(5005, 10, 1, n'invalid employee no') return @@error

back in vb.net test sql exception , found when employee no invalid error.number not 5005 expect, 2732.

what explanation this?

thank you.

you can't raise error 5005 in own code. db engine can this.

error 2732 error says can't raise messages < 50000

select description sys.sysmessages m m.error = 2732 , msglangid = 1033  error number %ld invalid. number must %ld through %ld , cannot 50000.
