I have a simple stored procedure on MS SQL 2012 Express that returns a result doing something like :
DECLARE #value INT;
SELECT #value;
Meanwhile I am trying to call this stored procedure doing something like
DECLARE #result INT;
EXEC #result = SpFoo .....
However the value I get on #result from the SpFoois 0.
How can I get the real value returned from the Stored Procedure?
Thanks
First declare #Value as output parameter in your called sp
CREATE PROCEDURE spCallee
#Value INT Output
AS
BEGIN
set #Value = 1
END
GO
Get result like this in caller sp
CREATE PROCEDURE spCaller
AS
BEGIN
declare #Result as int = 0
EXEC spCallee #Value = #Result Output
Select #Result
END
GO
The only way I know is to put result to the table and then get it from it:
DECLARE #tmp TABLE (Result int)
DECLARE #res int
INSERT INTO #tmp
EXECUTE [Procedure]...
SELECT #res = Result
FROM #tmp
I have a scenario wherein i have to execute an SP for specified number of time(number of execution will be mentioned by user) without using loop.
My SP is setting an OUTPUT variable of varchar type. I am willing to insert the output of my SP into a temp table and use it for further processing.
I am unable to modify this SP into function as it contain an Update statement.
Kindly suggest if we can do so without loop.
Whit this solution you do not need an output; #res is your result directly set in a temp table.
CREATE PROCEDURE [dbo].[myStoredProc]
#Counter int,
#params nvarchar(64),
#CreateTable bit
AS
DECLARE #res varchar(64)
IF #CreateTable = 1
BEGIN
IF EXISTS (SELECT 1 FROM dbo.sysobjects WHERE id = object_id(N'[#tempTable]'))
DROP TABLE #tempTable
CREATE TABLE #tempTable ([Res] [nvarchar] (64))
END
SET #res = CONVERT(varchar(64), #Counter)
SET #Counter = #Counter - 1
IF #Counter > 0
exec myStoredProc #Counter, #params, 0
INSERT #tempTable VALUES (#res)
IF #CreateTable = 1
BEGIN
SELECT * FROM #tempTable
DROP TABLE #tempTable
END
GO
DECLARE #o varchar(64)
exec [myStoredProc] 5, '', 1
I have this stored procedure that has a value:
BEGIN TRY
BEGIN TRANSACTION;
-- Insert statements for procedure here
DECLARE #return_value int
DECLARE #media_id uniqueidentifier
'INSERT SQL STATEMENT HERE
SELECT [media_id] FROM [media] WHERE 1 = 1
-- One row affected
RETURN 1
END TRY
BEGIN CATCH
IF ##TRANCOUNT > 0
BEGIN
ROLLBACK TRANSACTION;
END
-- Rollback, no row affected
RETURN 0
END CATCH;
I want to call the [media_id] value from another stored procedure. How do I get that value?
Table Definition
CREATE TABLE MY_EMPLOYEE
(EMPID INT, NAME VARCHAR(20),
LANGUAGEID INT , ID UNIQUEIDENTIFIER DEFAULT NEWID())
GO
Stored Procedure
ALTER PROCEDURE usp_ProcName
#Emp_ID INT = null,
#Name VARCHAR(20) = null,
#LanguageID int = null,
#NewID UNIQUEIDENTIFIER OUTPUT
AS
BEGIN
SET NOCOUNT ON;
BEGIN TRY
BEGIN TRANSACTION;
-- Insert statements for procedure here
INSERT INTO [Practice_DB].[dbo].[MY_EMPLOYEE](EMPID, NAME, LANGUAGEID)
VALUES (#Emp_ID, #Name, #LanguageID);
-- Populating the OUTPUT variable using the other variables that were passed
-- for INSERT statement.
SELECT #NewID = ID
FROM [Practice_DB].[dbo].[MY_EMPLOYEE]
WHERE EMPID = #Emp_ID
-- One row affected
COMMIT TRANSACTION
RETURN 1
END TRY
BEGIN CATCH
IF ##TRANCOUNT > 0
BEGIN
ROLLBACK TRANSACTION;
END
-- Rollback, no row affected
RETURN 0
END CATCH
END
GO
Calling Stored Procedure
DECLARE #value int, #ID VARCHAR(100)
EXECUTE #value = usp_ProcName
#Emp_ID = 50,
#Name = 'John',
#LanguageID = 50,
#NewID = #ID OUTPUT --<-- passing this variable with OUTPUT key word this will be
-- populated inside the Procedure and then you can SELECT it or
-- whatever you want to do with this value.
SELECT #ID
SELECT #value
This should help: Return Data from a Stored Procedure
I think this should work
BEGIN TRY
BEGIN TRANSACTION;
-- Insert statements for procedure here
DECLARE #return_value int
DECLARE #media_id uniqueidentifier
--get the value from the stored procedure here
Declare #SQL varchar(max)
set #SQL='INSERT SQL STATEMENT HERE
SELECT #media_id FROM [media] WHERE 1 = 1'
exec #SQL
-- One row affected
RETURN 1
END TRY
I'm trying to find out how to return the output parameter of a stored procedure when executing the stored procedure inside another stored procedure:
CREATE PROCEDURE Test1
EXEC SpWithOutputID -- Outputs #ID
SELECT #ID as ID -- Output #ID now being used in this SP
This is of course not my code, but just an example, is it possible to do this?
Example 2:
--Here #ID returns Null
CREATE PROCEDURE Test1
As
DECLARE #ID int
EXEC SpWithOutputID #ID = #ID OUTPUT -- Outputs #ID
SELECT #ID as ID -- Output #ID now being used in this SP
Example 3:
--Here #ID returns an Int
CREATE PROCEDURE Test1
As
EXEC SpWithOutputID -- Outputs #ID
If this isn't really an output parameter issue at all, but rather a result set, then taking a guess that SpWithOutputID does something like this (returns a SELECT with a single row and single column):
CREATE PROCEDURE dbo.SpWithOutputID
AS
BEGIN
SET NOCOUNT ON;
SELECT ID = 4;
END
GO
Then Test1 could look like this:
CREATE PROCEDURE dbo.Test1
AS
BEGIN
SET NOCOUNT ON;
DECLARE #ID INT;
CREATE TABLE #x(ID INT);
INSERT #x EXEC dbo.SpWithOutputID;
SELECT TOP (1) #ID = ID FROM #x;
DROP TABLE #x;
END
GO
But doesn't that look really messy to you? It really should work this way for single, scalar values:
CREATE PROCEDURE dbo.SpWithOutputID
#ID INT OUTPUT
AS
BEGIN
SET NOCOUNT ON;
SELECT #ID = 4;
END
GO
Now it is much simpler to consume what is really an output parameter now:
CREATE PROCEDURE dbo.Test1
AS
BEGIN
SET NOCOUNT ON;
DECLARE #ID INT;
EXEC dbo.SpWithOutputID #ID = #ID OUTPUT;
SELECT #ID;
END
GO
I have a stored procedure that I am trying to test. I am trying to test it through SQL Management Studio. In order to run this test I enter ...
exec my_stored_procedure 'param1Value', 'param2Value'
The final parameter is an output parameter. However, I do not know how to test a stored procedure with output parameters.
How do I run a stored procedure with an output parameter?
The easy way is to right-click on the procedure in Sql Server Management Studio (SSMS), select 'Execute stored procedure..." and add values for the input parameters as prompted. SSMS will then generate the code to run the procedure in a new query window, and execute it for you. You can study the generated code to see how it is done.
you can do this :
declare #rowCount int
exec yourStoredProcedureName #outputparameterspOf = #rowCount output
Return val from procedure
ALTER PROCEDURE testme #input VARCHAR(10),
#output VARCHAR(20) output
AS
BEGIN
IF #input >= '1'
BEGIN
SET #output = 'i am back';
RETURN;
END
END
DECLARE #get VARCHAR(20);
EXEC testme
'1',
#get output
SELECT #get
Check this, where the first two parameters are input parameters and the 3rd is an Output parameter in the Procedure definition.
DECLARE #PK_Code INT;
EXEC USP_Validate_Login 'ID', 'PWD', #PK_Code OUTPUT
SELECT #PK_Code
Procedure Example :
Create Procedure [dbo].[test]
#Name varchar(100),
#ID int Output
As
Begin
SELECT #ID = UserID from tbl_UserMaster where Name = #Name
Return;
END
How to call this procedure
Declare #ID int
EXECUTE [dbo].[test] 'Abhishek',#ID OUTPUT
PRINT #ID

CREATE PROCEDURE Myproc
#parm varchar(10),
**#parm1OUT varchar(30) OUTPUT**,
**#parm2OUT varchar(30) OUTPUT**
AS
SELECT #parm1OUT='parm 1' + #parm
SELECT #parm2OUT='parm 2' + #parm
GO
DECLARE #SQLString NVARCHAR(500)
DECLARE #ParmDefinition NVARCHAR(500)
DECLARE #parmIN VARCHAR(10)
DECLARE #parmRET1 VARCHAR(30)
DECLARE #parmRET2 VARCHAR(30)
SET #parmIN=' returned'

GO
DROP PROCEDURE Myproc
First, declare the output variable:
DECLARE #MyOutputParameter INT;
Then, execute the stored procedure, and you can do it without parameter's names, like this:
EXEC my_stored_procedure 'param1Value', #MyOutputParameter OUTPUT
or with parameter's names:
EXEC my_stored_procedure #param1 = 'param1Value', #myoutput = #MyOutputParameter OUTPUT
And finally, you can see the output result by doing a SELECT:
SELECT #MyOutputParameter
With this query you can execute any stored procedure (with or without an output parameter):
DECLARE #temp varchar(100)
EXEC my_sp
#parameter1 = 1,
#parameter2 = 2,
#parameter3 = #temp output,
#parameter4 = 3,
#parameter5 = 4
PRINT #temp
Here the datatype of #temp should be the same as #parameter3 within your Stored Procedure.
How about this? It's extremely simplified:
The SPROC below has an output parameter of #ParentProductID
We want to select the value of the output of #ParentProductID into #MyParentProductID which is declared below.
Here's the Code:
declare #MyParentProductID int
exec p_CheckSplitProduct #ProductId = 4077, #ParentProductID = #MyParentProductID output
select #MyParentProductID
Try this; it's working fine for the multiple output parameter:
CREATE PROCEDURE [endicia].[credentialLookup]
#accountNumber varchar(20),
#login varchar(20) output,
#password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 #login = [carrierLogin],#password = [carrierPassword]
FROM [carrier_account] where carrierLogin = #accountNumber
order by clientId, id
END
Try for the result:
SELECT *FROM [carrier_account]
DECLARE #login varchar(20),#password varchar(50)
exec [endicia].[credentialLookup] '588251',#login OUTPUT,#password OUTPUT
SELECT 'login'=#login,'password'=#password
CREATE PROCEDURE DBO.MY_STORED_PROCEDURE
(#PARAM1VALUE INT,
#PARAM2VALUE INT,
#OUTPARAM VARCHAR(20) OUT)
AS
BEGIN

END
DECLARE #OUTPARAM2 VARCHAR(20)
EXEC DBO.MY_STORED_PROCEDURE 1,#OUTPARAM2 OUT
PRINT #OUTPARAM2
Here is the stored procedure
create procedure sp1
(
#id as int,
#name as nvarchar(20) out
)
as
begin
select #name=name from employee where id=#id
end
And here is the way to execute the procedure
declare #name1 nvarchar(10)
exec sp1 1,#name1 out
print #name1
Please check below example to get output variable value by executing a stored procedure.
DECLARE #return_value int,
#Ouput1 int,
#Ouput2 int,
#Ouput3 int
EXEC #return_value = 'Your Sp Name'
#Param1 = value1,
#Ouput1 = #Ouput1 OUTPUT,
#Ouput2 = #Ouput2 OUTPUT,
#Ouput3 = #Ouput3 OUTPUT
SELECT #Ouput1 as N'#Ouput1',
#Ouput2 as N'#Ouput2',
#Ouput3 as N'#Ouput3'
Here is the definition of the stored_proc:
create proc product(#a int,#b int)
as
return #a * #b
And, this is executing it from Python:
conn = pyodbc.connect('...')
cursor = conn.cursor()
sql = """
SET NOCOUNT ON
declare #r float
exec #r=dbo.product 5,4
select #r
"""
result = cursor.execute(sql)
print (result.fetchall())
