Retrieving a particular value in SQL Server - sql-server

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

Getting rows affected in stored procedure INSERT statement with NOCOUNT OFF

I have a stored procedure in SQL Server 2014 where I first delete data from a table and execute another stored procedure as shown below. I don't care about rows affected on this code so I use SET NOCOUNT ON. I then perform an Insert statement first setting SET NOCOUNT OFF. I would expect the stored procedure to return the rows affected automatically from the INSERT but that has not proven to be the case. I searched SO and found the ##ROWCOUNT and that is working. However, is that really required? Why wouldn't the INSERT statement in the code below return the records affected?
ALTER PROCEDURE [dbo].[SaveTextSetting]
#UserId INT ,
#SettingType INT = 0 ,
#SettingValue NVARCHAR(MAX)
AS
BEGIN
BEGIN
SET NOCOUNT ON;
DELETE FROM Settings
WHERE UserId = #UserId
AND SettingType = #SettingType;
EXEC dbo.PurgeExpiredSettings;
END;
BEGIN
SET NOCOUNT OFF;
INSERT INTO dbo.Settings
( UserId ,
SettingsText ,
SettingType
)
VALUES ( #UserId ,
#SettingValue ,
#SettingType
);
RETURN ##ROWCOUNT; --without this we don't get the rows affected
END;
END;
Are you sure?
CREATE PROCEDURE spTest AS RETURN
GO
ALTER PROCEDURE spTest
AS
BEGIN
SET NOCOUNT OFF
DECLARE #rt int
CREATE TABLE #t (
v int NOT NULL
)
INSERT INTO #t (v)
SELECT v FROM (VALUES (1), (1), (2)) AS t (v)
SET #rt = ##ROWCOUNT
DROP TABLE #t
RETURN #rt
END
GO
DECLARE #rt int
EXEC #rt = spTest
SELECT #rt
GO
DROP PROCEDURE spTest
GO
I would use an output param something like.....
ALTER PROCEDURE [dbo].[SaveTextSetting]
#UserId INT ,
#SettingType INT = 0 ,
#SettingValue NVARCHAR(MAX),
#RowCount INT OUTPUT
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM Settings
WHERE UserId = #UserId
AND SettingType = #SettingType;
EXEC dbo.PurgeExpiredSettings;
INSERT INTO dbo.Settings( UserId ,SettingsText ,SettingType)
VALUES ( #UserId ,#SettingValue ,#SettingType);
SET #RowCount= ##ROWCOUNT;
END

SQL SERVER : How to execute an SP specifed number of time without using loop

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

If else doesn't work in stored procedures

I have two stored procedures to select and insert values.When I choose an item from Listbox and click the add button, the code calls SP$select. Then a new Form appears and I give the data into the textbox. When I click save button, SP$insert works. But all the data can be only inserted into the first(Base) column. When I do all actions in SP$insert (select and insert) then it doesn't work. What's wrong with it?
Procedure 1 [SP$select]
use env
go
create proc [SP$select](
#p2 nvarchar(20),
#debug bit = 0)
as
begin
set nocount on
begin try
if #p2='User Name'
begin
SELECT user_name FROM env.dbo.Base
end
else if #p2='Serial Number'
begin
SELECT ser_num FROM env.dbo.Base
end
end try
begin catch
IF #debug = 1
throw;
end catch
end
set nocount off
go
Procedure 2 [SP$insert]
use env
go
create proc [SP$insert](
#p1 nvarchar(100),
#id int output,
#debug bit = 0)
as
begin
set nocount on
begin try
if exists(select user_name from env.dbo.Base)
begin
INSERT INTO envanter.dbo.Base(user_name) VALUES (#p1)
SELECT #id = ##IDENTITY
end
else if exists(select ser_num from env.dbo.Base)
begin
INSERT INTO env.dbo.Base(ser_num) VALUES (#p1)
SELECT #id = ##IDENTITY
end
end try
begin catch
if #debug = 1
throw;
end catch
set nocount off
end
go
try this code
use env
go
create proc [SP$insert](
#p1 nvarchar(100),
#id int output,
#debug bit = 0)
as
begin
set nocount on
begin try
if exists(select user_name from env.dbo.Base)
begin
INSERT INTO envanter.dbo.Base(user_name) VALUES (#p1)
SELECT #id = ##IDENTITY
end
if exists(select ser_num from env.dbo.Base)
begin
INSERT INTO env.dbo.Base(ser_num) VALUES (#p1)
SELECT #id = ##IDENTITY
end
end try
begin catch
if #debug = 1
throw;
end catch
set nocount off
end
go
Not sure what you are trying to do here. If there is at least one row on table Base the statement "if exists(select user_name from env.dbo.Base)" whill always be TRUE regardless of whether the user_name value is null or not, therefore the "else if" part will never happen.

How to know TSQL Stored Procedure Update Executed

How can I check if my TSQL stored procedure updated within the stored procedure in order to create a proper message?
Example:
ALTER PROCEDURE [dbo].[pUpdate]
#id uniqueidentifier,
#status int,
#message VARCHAR(100) OUTPUT
AS
BEGIN
SET NOCOUNT ON;
UPDATE [database].[dbo].[user]
SET status = #status
WHERE Id = #id
END
IF (SUCCESSFUL)
BEGIN
#message = 'Success!'
END
What are some possible ways to check if successful without using the parameters again?
This is what I currently use:
SELECT COUNT(*)
WHERE status = #status AND id = #id
Are there any other ways? I want to know for my knowledge and reference. Thanks.
Have you checked out ##ROWCOUNT? Might be what you're looking for (see this for details: http://technet.microsoft.com/en-us/library/ms187316.aspx). Basically it returns the number of rows affected by the last statement. I'd imagine if it were not "successful", it would be zero rows.
ALTER PROCEDURE [dbo].[pUpdate]
#id uniqueidentifier,
#status int,
#message VARCHAR(100) OUTPUT
AS
BEGIN
SET NOCOUNT ON;
UPDATE [database].[dbo].[user]
SET status = #status
WHERE Id = #id
END
IF (##ROWCOUNT > 0)
BEGIN
#message = 'Success!'
END
ELSE
BEGIN
#message = 'Not success!'
END
You can use a try catch block and log the success or failure to a table.
BEGIN TRY
BEGIN TRANSACTION
-- Add Your Code Here
-- Log Success to a log table
COMMIT
END TRY
BEGIN CATCH
-- Log failure to a log table
ROLLBACK
END CATCH
I would use ##ERROR system variable to check whether the last sentence was successfull (error # = 0) or not (error # > 0 ):
USE Database;
GO
BEGIN
UPDATE TableName
SET ColumnA = 4
WHERE ColumnB = 1;
END
IF (##ERROR = 0)
BEGIN
PRINT N'Successfull Update';
GO
END
You can go deeper into Microsoft MSDN here: http://technet.microsoft.com/es-es/library/ms188790.aspx
ALTER PROCEDURE [dbo].[pUpdate]
#id uniqueidentifier,
#status int,
#message VARCHAR(100) OUTPUT
AS
BEGIN
SET NOCOUNT ON;
UPDATE [database].[dbo].[user]
SET status = #status
WHERE Id = #id
END
IF (##ROWCOUNT > 0)
BEGIN
SELECT #message = 'Success!'
END
ELSE
BEGIN
SELECT #message = 'Not success!'
END

Call Stored Procedure within Create Trigger in SQL Server

I have a stored procedure named insert2Newsletter with parameters
(#sex nvarchar(10),
#f_name nvarchar(50),
#l_name nvarchar(70),
#email nvarchar(75),
#ip_address nvarchar(50),
#hotelID int,
#maArt nchar(2))
I want call this stored procedure in an insert trigger. How do I retrieve the corresponding fields from inserted and how do i call insert2Newsletter within the trigger?
I tried without success:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER RA2Newsletter
ON [dbo].[Reiseagent]
AFTER INSERT
AS
DECLARE #rAgent_Name nvarchar(50),
DECLARE #rAgent_Email nvarchar(50),
DECLARE #rAgent_IP nvarchar(50),
DECLARE #hotelID int
BEGIN
SET NOCOUNT ON;
-- Insert statements for trigger here
Select #rAgent_Name=rAgent_Name, #rAgent_Email=rAgent_Email, #rAgent_IP=rAgent_IP, #hotelID=hotelID From Inserted
EXEC insert2Newsletter '','',#rAgent_Name,#rAgent_Email,rAgent_IP,#hotelID,'RA'
END
GO
thx a lot for your feedback... greetings...
I think you will have to loop over the "inserted" table, which contains all rows that were updated. You can use a WHERE loop, or a WITH statement if your primary key is a GUID. This is the simpler (for me) to write, so here is my example. We use this approach, so I know for a fact it works fine.
ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
AFTER INSERT
AS
-- This is your primary key. I assume INT, but initialize
-- to minimum value for the type you are using.
DECLARE #rAgent_ID INT = 0
-- Looping variable.
DECLARE #i INT = 0
-- Count of rows affected for looping over
DECLARE #count INT
-- These are your old variables.
DECLARE #rAgent_Name NVARCHAR(50)
DECLARE #rAgent_Email NVARCHAR(50)
DECLARE #rAgent_IP NVARCHAR(50)
DECLARE #hotelID INT
DECLARE #retval INT
BEGIN
SET NOCOUNT ON ;
-- Get count of affected rows
SELECT #Count = Count(rAgent_ID)
FROM inserted
-- Loop over rows affected
WHILE #i < #count
BEGIN
-- Get the next rAgent_ID
SELECT TOP 1
#rAgent_ID = rAgent_ID
FROM inserted
WHERE rAgent_ID > #rAgent_ID
ORDER BY rAgent_ID ASC
-- Populate values for the current row
SELECT #rAgent_Name = rAgent_Name,
#rAgent_Email = rAgent_Email,
#rAgent_IP = rAgent_IP,
#hotelID = hotelID
FROM Inserted
WHERE rAgent_ID = #rAgent_ID
-- Run your stored procedure
EXEC insert2Newsletter '', '', #rAgent_Name, #rAgent_Email,
#rAgent_IP, #hotelID, 'RA', #retval
-- Set up next iteration
SET #i = #i + 1
END
END
GO
I sure hope this helps you out. Cheers!
Finally ...
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[RA2Newsletter]
ON [dbo].[Reiseagent]
AFTER INSERT
AS
declare
#rAgent_Name nvarchar(50),
#rAgent_Email nvarchar(50),
#rAgent_IP nvarchar(50),
#hotelID int,
#retval int
BEGIN
SET NOCOUNT ON;
-- Insert statements for trigger here
Select
#rAgent_Name = rAgent_Name,
#rAgent_Email = rAgent_Email,
#rAgent_IP = rAgent_IP,
#hotelID = hotelID
From Inserted
EXEC insert2Newsletter
'',
'',
#rAgent_Name,
#rAgent_Email,
#rAgent_IP,
#hotelID,
'RA',
#retval
END
The following should do the trick - Only SqlServer
Alter TRIGGER Catagory_Master_Date_update ON Catagory_Master AFTER delete,Update
AS
BEGIN
SET NOCOUNT ON;
Declare #id int
DECLARE #cDate as DateTime
set #cDate =(select Getdate())
select #id=deleted.Catagory_id from deleted
print #cDate
execute dbo.psp_Update_Category #id
END
Alter PROCEDURE dbo.psp_Update_Category
#id int
AS
BEGIN
DECLARE #cDate as DateTime
set #cDate =(select Getdate())
--Update Catagory_Master Set Modify_date=''+#cDate+'' Where Catagory_ID=#id --#UserID
Insert into Catagory_Master (Catagory_id,Catagory_Name) values(12,'Testing11')
END
You pass an undefined rAgent_IP parameter in EXEC instead of the local variable #rAgent_IP.
Still, this trigger will fail if you perform a multi-record INSERT statement.
