| I'm pretty new in using SQL Srver with Visual Basic and the setuo of parameters in a stored procedure.Somewhere in the past I saw some examples that I think don't tell me the whole story. For instance this parameter was shown: @Authors nvarchar(60) = a, I understand that the =a is a default value and the string example I show ends up inserting an a in the field the legitametely should be blank.My concern is that i can find no documentation indicating the intent of the entry. Can anyone point me in the right direction?Milt |

'' is stored as a value in table whereas NULL is stored as a bit internally representing unknown value condition------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |
