BEGIN SET @ErrorToBeReturned = 'Your Custom Error Message' END ELSE BEGIN SET SET @ErrorToBeReturned = '' --YOUR CODE HERE END RETURN @ErrorToBeReturned Then you can use an ReturnValue Parameter to fetch the return value e.g. command().Parameters.Add("@ErrorMessage", SqlDbType.VarChar, 1024).Direction = ParameterDirection.ReturnValue; if (!Information.IsDBNull(command().Paramaters("@ErrorMessage").Value)) { lblError.Text = command().Paramaters("@ErrorMessage").Value.ToString; } Remember to click Mark As Answer when you get a reply which answers your question.

CREATE procedure [dbo].[SP_ProfileRegMaster] @UserId Varchar(50), @FirstName Varchar(50) @EmailID varchar (50) @result int out) as begin if exists(select EmailId from Profile_Master where EmailId=@EmailId) begin set @result=0 else RAISERROR ('Email address does not exist.', 1, 1) end result = cmd1.Parameters.Add("@result", System.Data.SqlDbType.Int); result.Direction = System.Data.ParameterDirection.Output; sql server stored c# sql-server share|improve this question edited Aug 8 '12 at 15:49 asked Aug 8 '12 at 15:08 Chandra sekhar 79518 you need to use SQL Client and do the code via C# code behind.. you need to look at examples on how to connect to SQL Server in C# and how to execute the query in C# Code passing params..etc –MethodMan Aug 8 '12 at 15:10 add a comment| 4 Answers 4 active oldest votes up vote 0 down vote accepted As I mentioned in my comment, I'd not use RAISERROR() in your case. You could do something like this: Stored Procedure CREATE procedure [dbo].[SP_ProfileRegMaster] @UserId Varchar(50), @FirstName Varchar(50) @EmailID varchar (50)) AS BEGIN if exists(select EmailId from Profile_Master where EmailId=@EmailId) begin return 0 else return 1 end end C# code SqlConnection conn = new SqlConnection(getConnectionString()) SqlCommand cmd = new SqlCommand("SP_ProfileRegMaster", conn); cmd.CommandType = CommandType.StoredProcedure; // Pass parameters to Stored Proc... // Add one more parameter to store the Return Value var returnParameter = cmd.Parameters.Add("@ReturnVal", SqlDbType.Int); returnParameter.Direction = ParameterDirection.ReturnValue; conn.Open(); cmd.ExecuteNonQuery(); // Retrieve the return value var result = returnParameter.Value; share|improve this answer answered Aug 9 '12 at 10:31 Diego 2,61421833 This is what i have done but i want to know about when and where can i use or implement RAISERROR more efficienlty? –Chandra sekhar
| 2 Comments | Tags: Stored Procedures The following article introduces the basics of handling errors in stored procedures. If you are not familiar with the difference between fatal and non-fatal errors, the system function @@ERROR, or how to add a custom error with the system stored procedure sp_addmessage, you should find it interesting. The examples presented here are specific to stored procedures as they are the desired method of interacting with a database. When an error is encountered within a stored procedure, the best you can do (assuming it’s a non-fatal error) is halt the sequential processing of the code and either branch to another code segment in the procedure or return processing to the calling application. Notice that the previous sentence is specific to non-fatal errors. There are two type of errors in SQL Server: fatal and non-fatal. Fatal errors cause a procedure to abort processing and terminate the connection with the client application. Non-fatal errors do not abort processing a procedure or affect the connection with the client application. When a non-fatal error occurs within a procedure, processing continues on the line of code that follows the one that caused the error. The following example demonstrates how a fatal error affects a procedure. USE tempdb go CREATE PROCEDURE ps_FatalError_SELECT AS SELECT * FROM NonExistentTable PRINT 'Fatal Error' go EXEC ps_FatalError _SELECT --Results-- Server:Msg 208,Level 16,State 1,Procedure ps_FatalError_SELECT,Line 3 Invalid object name 'NonExistentTable'. The SELECT in the procedure references a table that does not exist, which produces a fatal error. The procedure aborts processing immediately after the error and the PRINT statement is not executed. To demonstrate how a non-fatal error is processed, I need to create the following table. USE tempdb go CREATE TABLE NonFatal ( Column1 int IDENTITY, Column2 int NOT NULL ) This example uses a procedure to INSERT a row into NonFatal,
