asked on

get the value of return from a stored procedure

I have this in a stored procedure

RETURN @result;

that can be = 0 or 1

What would the .net code look like that would return it's value?

You just need to set your return parameter's Direction property to ParameterDirection.ReturnValue, and after you execute your command get return parameter's value like that :

SqlParameter myReturnParam = command.Parameters.Add("@MyReturnValue", SqlDbType.Int);
myReturnParam.Direction = ParameterDirection.ReturnValue;

// Execute your Command here, and get the value of your return parameter :  

int myReturnValue = (int)command.Parameters["@MyReturnValue"].Value;

I am sure you will get enough information in above URL.

Let me know for any more info.

THIS IS WHAT I AM DOING

SSS IS ALWAYS RETURNING 1




Dim Connection As SqlClient.SqlConnection = CreateConnection()

        Dim Command As New SqlClient.SqlCommand

        With Command
            .Connection = Connection
            .CommandText = "spValidateLogin "
            .CommandType = CommandType.StoredProcedure

            .Parameters.AddWithValue("@username", UserName)

            .Parameters.AddWithValue("@password", Password)
            .Parameters.AddWithValue("@ipaddress", IPAddress)
            .Parameters.AddWithValue("@result", "1")

            Dim parameterResult As SqlClient.SqlParameter = New SqlClient.SqlParameter("@result", SqlDbType.Int)
            .Parameters.Add(parameterResult)
            parameterResult.Direction = ParameterDirection.ReturnValue


            .ExecuteNonQuery()
            Dim sss As Integer
            sss = Command.Parameters("@result").Value
'sss IS ALWAYS RETURNING 1

        End With


       
due to:

.Parameters.AddWithValue("@result", "1")


can you please post sql output with col. name?
This

sss = parameterResult.Value

did the trick

For the case that gdupadhyay: explains, you need to set the parameter as OUTPUT parameter in the Stored Procedure.
CREATE PROCEDURE YourStoredProcedure
(
      @result INT OUTPUT
)
...

I think no need to explain, as you got it
sss = parameterResult.Value
