Returning multiple values from a stored procedure - sql

Question

I am using SQL Server. I am calling a stored procedure from another stored procedure.
I want to return multiple values from the first stored procedure.
Ex: I am calling Sub_SP from Master_SP. Sub_SP will return multiple values to Master_SP.
Can anyone give an example with OUTPUT parameters?
Thank you.

ALTER procedure ashwin #empid int,#empname varchar(20) output,#age int output
as
select #empname=ename,#age=age
from emp where empid=#empid;
declare #ename varchar(20),#age int
execute ashwin 101,#ename out,#age out
select #ename,#age;
//------------
namespace sqlserver
{
class Program
{
static void Main(string[] args)
{
createconnection();
}
public static void createconnection()
{
SqlConnection con=new SqlConnection("Data Source=ASHWIN\\SQLEXPRESS;Initial Catalog=employee;Integrated Security=True;Pooling=False");
con.Open();
SqlCommand cmd=new SqlCommand("ashwin",con);
cmd.CommandType=CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("#empid",SqlDbType.Int,10,"empid"));
cmd.Parameters.Add(new SqlParameter("#empname", SqlDbType.VarChar, 20,ParameterDirection.Output,false,0,20,"ename",DataRowVersion.Default,null));
cmd.Parameters.Add(new SqlParameter("#age", SqlDbType.Int, 20, ParameterDirection.Output, false, 0, 10, "age", DataRowVersion.Default, null));
cmd.Parameters[0].Value = 101;
cmd.UpdatedRowSource = UpdateRowSource.OutputParameters;
cmd.ExecuteNonQuery();
string name = (string)cmd.Parameters["#empname"].Value;
int age = Convert.ToInt32(cmd.Parameters["#age"].Value);
Console.WriteLine("the name is {0}--and age is {1}", name,age);
Console.ReadLine();
}
}

How about this:
CREATE PROCEDURE dbo.SubSP
#Value1 INT OUTPUT, #Value2 INT OUTPUT
AS
-- just return two values into the OUTPUT parameters somehow....
SELECT #Value1 = 42, #Value2 = 4711
Test the dbo.SubSP:
DECLARE #Out1 INT, #Out2 INT
EXEC dbo.SubSP #Out1 OUTPUT, #Out2 OUTPUT -- int
SELECT #Out1, #Out2
Gives output:
#Out1 #Out2
42 4711
Then create "master" stored procedure:
CREATE PROCEDURE dbo.MasterSP
#SomeValue1 INT OUTPUT, #SomeValue2 INT OUTPUT, #SomeValue3 INT OUTPUT
AS BEGIN
DECLARE #Out1 INT, #Out2 INT
-- call the "sub" stored procedure and capture OUTPUT values
EXEC dbo.SubSP #Out1 OUTPUT, #Out2 OUTPUT
-- return those values - plus some others - from master stored procedure
SELECT #SomeVAlue1 = #Out1, #SomeVAlue2 = #Out2, #SomeValue3 = 9901
END
Test master stored proc:
DECLARE #Some1 INT, #Some2 INT, #Some3 INT
EXECUTE dbo.MasterSP #Some1 OUTPUT, #Some2 OUTPUT, #Some3 OUTPUT
SELECT #Some1, #Some2, #Some3
Gives output:
(No column name) (No column name) (No column name)
42 4711 9901
Does this work? Does this solve your problem? If not: where are you stuck, what exactly is the problem?

I had the same problem and I am working in VB. I have tried the #Scorpian275 's answer. This is the same solution as #Scorpian275 provided but it is for the VB. The sql part is the same.
Public Shared Sub createConnection()
Dim con As SqlConnection = New SqlConnection("Data Source=ASHWIN\\SQLEXPRESS;Initial Catalog=employee;Integrated Security=True;Pooling=False")
con.Open
Dim cmd As SqlCommand = New SqlCommand("ashwin", con)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New SqlParameter("#empid", SqlDbType.Int, 10, "empid"))
cmd.Parameters.Add(New SqlParameter("#empname", SqlDbType.VarChar, 20, ParameterDirection.Output, false, 0, 20, "ename", DataRowVersion.Default, Nothing))
cmd.Parameters.Add(New SqlParameter("#age", SqlDbType.Int, 20, ParameterDirection.Output, false, 0, 10, "age", DataRowVersion.Default, Nothing))
cmd.Parameters(0).Value = 101
cmd.UpdatedRowSource = UpdateRowSource.OutputParameters
cmd.ExecuteNonQuery
Dim name As String = CType(cmd.Parameters("#empname").Value,String)
Dim age As Integer = Convert.ToInt32(cmd.Parameters("#age").Value)
Console.WriteLine("the name is {0}--and age is {1}", name, age)
Console.ReadLine
End Sub
The last parameter in
cmd.Parameters.Add(New SqlParameter("#age", SqlDbType.Int, 20, ParameterDirection.Output, false, 0, 10, "age", DataRowVersion.Default, Nothing))
is the initial value that we provide for those variables (Here Nothing).
