How to deal with return value of stored procedure when you are using DataReader ?

Posted By :shah268     Posted Date :November 26, 2009    Points :10   Category :.NET Framework 
To deal with such scenario, you can find "ParameterDirection.ReturnValue" in .net
You can use this parameter direction to read the return value of the stored procedure.

Following example can make it more clearer.
In case, you have following or similar type of return statement somewhere in your stored procedure.
Return -999
To read this value, following code works,

Dim result As Integer = 0
Dim retValParam As New SqlClient.SqlParameter("@RETURN_VALUE", SqlDbType.Int)
retValParam.Direction = ParameterDirection.ReturnValue
dbCommand.Parameters.Add(retValParam)
database.ExecuteNonQuery(dbCommand)
result = retValParam.Value ' here the result must contain the returned value. In this case, it will be -999

What is a Stored Procedure?

  
Its nothing but a set of T-SQL statements combined to perform a single task of several tasks. Its basically like a Macro so when you invoke the Stored procedure, you actually run a set of statements. (More...)

Difference between Function and Stored Procedure?

  
UDF can be used in the SQL statements anywhere in the WHERE/HAVING/SELECT section where as Stored procedures cannot be.
UDFs that return tables can be treated as another rowset. This can be used in JOINs with other tables.
Inline UDF's can be though of as views that take parameters and can be used in JOINs and other Rowset operations.
(More...)

How will you prevent the user from viewing the text of the Stored Procedure?

  
We can use with Encryption in the Stored Procedure.

What is Difference between Function and Stored Procedure?

  
UDF can be used in the SQL statements anywhere in the WHERE/HAVING/SELECT section where as Stored procedures cannot be. UDFs that return tables can be treated as another rowset. This can be used in JOINs with other tables. Inline UDF's can be thought of as views that take parameters and can be used in JOINs and other Rowset operations. (More...)

This catalog SP returns objects of type: Tables and Views. This includes system tables as well. (More...)

Can a stored procedure call itself or recursive stored procedure? How many level SP nesting possible?

  
Yes. Because Transact-SQL supports recursion, you can write stored procedures that call themselves. Recursion can be defined as a method of problem solving wherein the solution is arrived at by repetitively applying it to subsets of the problem. A common application of recursive logic is to perform numeric computations that lend themselves to repetitive evaluation by the same processing steps.
Stored procedures are nested when one stored procedure calls another or executes managed code by referencing a CLR routine, type, or aggregate. You can nest stored procedures and managed code references up to 32 levels. (More...)
