Question

I want to know what does RETURN_VALUE mean! I’m stuck at this thing. How to use RETURN_VALUE in a SQL Server stored procedure? thanks..

ASP:

Set cmdDB = Server.CreateObject("ADODB.Command")
With cmdDB
   .ActiveConnection = ADOConM
   .CommandText = "usp_jaljava_member_select"
   .CommandType = adCmdStoredProc
   .Parameters.Append .CreateParameter("RETURN_VALUE", adInteger, adParamReturnValue, 0)
   .Parameters.Append .CreateParameter("@TLoginName", adVarChar, adParamInput, 15, lcase(TLoginName))
   .Parameters.Append .CreateParameter("@TPassword", adVarChar, adParamInput, 20, TPassword)
   .Parameters.Append .CreateParameter("@retval", adVarChar, adParamOutput, 50)

‘ .Parameters.Append .CreateParameter(“@TPinCode”, adVarChar, adParamInput, 15,TPinCode)
.Execute,,adExecuteNoRecords

   RetVal = .Parameters("@retval")
   Ret = Trim(.Parameters("RETURN_VALUE"))

   'Set .ActiveConnection = Nothing
End With
Set cmdDB = Nothing

UTid = RetVal

SQL Server stored procedure:

CREATE PROCEDURE usp_jaljava_member_select 
   @TLoginName varchar(15),
   @TPassword varchar(20),
   @retval varchar(50) OUTPUT
   --@TPinCode varchar(15)
AS

A MS SQL stored procedure can return a return value – this is apart from output parameters.

The code above gives you access to this return value.

See MSDN for more information (RETURN (Transact-SQL)).

So, for the following stored procedure:

CREATE PROCEDURE checkstate @param varchar(11)
AS
   IF (SELECT StateProvince FROM Person.vAdditionalContactInfo WHERE ContactID = @param) = 'WA'
   RETURN 1
ELSE
   RETURN 2;
GO

The following code would set Ret to 1 or 2, depending on the passed in parameter and data:

Set cmdDB = Server.CreateObject("ADODB.Command")
With cmdDB
    .ActiveConnection = ADOConM
    .CommandText = "checkstate"
    .CommandType = adCmdStoredProc
    .Parameters.Append .CreateParameter("RETURN_VALUE", adInteger, adParamReturnValue, 0)
    .Parameters.Append .CreateParameter("@param", adVarChar, adParamInput, 11, "Contact")

    .Execute,,adExecuteNoRecords

    Ret = Trim(.Parameters("RETURN_VALUE"))

End With
Set cmdDB = Nothing
