I want to execute a stored procedure in SQL Server and assign the output to a string.
CREATE PROCEDURE sp_Check_User_Password
#name NVARCHAR(30),
#email NVARCHAR(50)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #pass NVARCHAR(50)
IF EXISTS(SELECT dbo.Mitarbeiter.Name, dbo.Mitarbeiter.Email
FROM dbo.Mitarbeiter
WHERE dbo.Mitarbeiter.Name = #name
AND dbo.Mitarbeiter.Email = #email
BEGIN
SET #pass = dbo.Mitarbeiter.Password
END
ELSE
BEGIN
SET #pass = null
END
RETURN #pass
END
I have changed what I wrote wrong
Have a look on below sample, just add your stuff and it will work
CREATE PROCEDURE return_string
(#param1 NVARCHAR(10),
#param2 NVARCHAR(10),
#output NVARCHAR(10) OUT)
AS
BEGIN
IF (1=1)
SET #output = 'here'
else
SET #output = null
END
to test
declare #out nvarchar(10)
exec return_string 'firdt param', 'second param', #out out
select #out
I hope this will help you achive what you need.
So your SP would look like:
CREATE PROCEDURE sp_Check_User_Password
(
#name nvarchar(30),
#email nvarchar(50),
#pass nvarchar(50) OUT
)
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS(SELECT 1
FROM dbo.Mitarbeiter
WHERE dbo.Mitarbeiter.Name = #name
and dbo.Mitarbeiter.Email = #email)
BEGIN
SET #pass = (SELECT dbo.Mitarbeiter.Name
FROM dbo.Mitarbeiter
WHERE dbo.Mitarbeiter.Name = #name
and dbo.Mitarbeiter.Email = #email)
END
ELSE
BEGIN
SET #pass = null
END
END
I'll take a stab at it. Is this what you're trying to do?
CREATE PROCEDURE sp_Check_User_Password
#name nvarchar(30),
#email nvarchar(50)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #pass nvarchar(50) = null
IF EXISTS(SELECT dbo.Mitarbeiter.Email FROM dbo.Mitarbeiter
WHERE dbo.Mitarbeiter.Name = #name and dbo.Mitarbeiter.Email = #email)
BEGIN
SELECT #pass = dbo.Mitarbeiter.Email FROM dbo.Mitarbeiter
WHERE dbo.Mitarbeiter.Name = #name and dbo.Mitarbeiter.Email = #email
END
PRINT #pass
END

This is my stored procedure:
CREATE PROCEDURE MYSP
(#PARAM INT,
#PARAM2 NVARCHAR(34),
#OUTPARAM3 NVARCHAR(34) OUTPUT)
AS
BEGIN
DECLARE #RParam INT
DECLARE #ErrParam2 NVARCHAR(34)
IF(#PARAM = 1 AND #PARAM2 = 'abc' )
BEGIN
SET #OUTPARAM3 = 'EQUAL'
SET #RPARAM = 0
END
ELSE
BEGIN
SET #ERRPARAM2 = 'SOME ERROR..MSG'
SET #RPARAM = -1
END
RETURN #RPARAM
END
And I am trying to get the value of the internally declare variable value.
DECLARE #RParam INT
DECLARE #ErrParam2 NVARCHAR(34)
#RParam is returned but how can I return #ErrParam2 value?
Declare #RP int
Declare #ErrMsg Nvarchar(40)
Exec #RP = MYSP 1,'abc'
You need to specify the output parameter both when the stored procedure is defined and when it is called:
Declare #RP int;
Declare #ErrMsg Nvarchar(40);
Exec #RP = MYSP 1, 'abc' , #ErrMsg output;
I have a table with the user details like
id
fname
lname
role
branch
email
password
I have a stored procedure for the login validation which takes the values of email and password, validates and send out the success message.
The validation is working now. I need to fetch the values of fname, lname, role and branch too.
Here is the code:
USE [Project]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[usp_loginuser]
(#Email varchar(100),
#password varchar(100)
)
AS
BEGIN
DECLARE #msg nvarchar(2048)
SET NOCOUNT ON
--select * from dbo.userdetails where email=#userEmail and pwd=#password
BEGIN TRY
Declare #flag bit
SET #flag = 0
IF EXISTS(Select * from userdetails
where ltrim(rtrim(email)) = ltrim(rtrim(#Email)) AND ltrim(rtrim(pwd)) = ltrim(rtrim(#password))
AND isactive = 1)
BEGIN
SET #flag =1;
END
ELSE
BEGIN
SET #flag =0;
END
SELECT #flag [IsSuccess]
END TRY
BEGIN CATCH
SET #msg = error_message()
RAISERROR (#msg, 16, 1)
END CATCH
SET NOCOUNT OFF
END
Here is the code
ALTER Procedure [dbo].[usp_loginuser]
(#Email varchar(100),
#password varchar(100),
#fname varchar(100) output,
#lname varchar(100) output
)
AS
BEGIN
DECLARE #msg nvarchar(2048)
SET NOCOUNT ON
BEGIN TRY
Declare #flag bit
SET #flag = 0
IF EXISTS(Select #fname = fname, #lname = lname from userdetails
where ltrim(rtrim(email)) = ltrim(rtrim(#Email)) AND ltrim(rtrim(pwd)) = ltrim(rtrim(#password))
AND isactive = 1)
BEGIN
SET #flag =1;
END
ELSE
BEGIN
SET #flag =0;
END
SELECT #flag [IsSuccess], #fname, #lname
END TRY
BEGIN CATCH
SET #msg = error_message()
RAISERROR (#msg, 16, 1)
END CATCH
SET NOCOUNT OFF
END
BEGIN TRY
Declare #flag bit
SET #flag = 0
IF EXISTS(Select * from userdetails
where ltrim(rtrim(email)) = ltrim(rtrim(#Email)) AND ltrim(rtrim(pwd)) = ltrim(rtrim(#password))
AND isactive = 1)
BEGIN
SET #flag =1;
END
ELSE
BEGIN
SET #flag =0;
END
SELECT fname, lname, role, branch from userdetails
where ltrim(rtrim(email)) = ltrim(rtrim(#Email)) AND ltrim(rtrim(pwd)) = ltrim(rtrim(#password))
END TRY
If you get an empty data set, its a failure else success

The timeout occurs due to two updates to same table inside same transaction. You could avoid it with a case statement. Also whole IF ELSE can be replaced with a merge.

Try it and check whether this is what you expected.
Already discussed here
You can achieve it using sp_getapplock in TSQL.
But you need a wrapper storedproc or batch for this. Check the following example it will help you to desing your wrapper sp/batch statement.
Sample Code Snippet
Create table MyTable
(
RowId int identity(1,1),
HitStartedAt datetime,
HitTimestamp datetime,
UserName varchar(100)
)
Go
Create proc LegacyProc (#user varchar(100), #CalledTime datetime)
as
Begin
Insert Into MyTable
Values(#CalledTime, getdate(), #user);
--To wait for 10 sec : not required for your procedures, producing the latency to check the concurrent users action
WAITFOR DELAY '000:00:10'
End
Go
Create Proc MyProc
(
#user varchar(100)
)
as
Begin
Declare #PorcName as NVarchar(1000), #CalledTime datetime
Begin Tran
--To get the Current SP Name, it should be unique for each SP / each batch
SET #PorcName = object_name(##ProcID)
SET #CalledTime = Getdate()
--Lock the Current Proc
Exec sp_getapplock #Resource = #PorcName, #LockMode = 'Exclusive'
--Execute Your Legacy Procedures
Exec LegacyProc #user, #CalledTime
--Release the lock
Exec sp_releaseapplock #Resource = #PorcName
Commit Tran
End
You are doing two seperate updates on the DeviceCatalog table where [UniqueID] = #UniqueID in the same transaction.
I bet your locking/request timeout issue is happening when:
IF (#OldGeo IS NULL OR #OldAddress IS NULL OR #OldCity IS NULL OR #OldCountry IS NULL OR ISNULL(#Geo.STDistance(#OldGeo) / 1000,0) > 50) is true.
Try something like this in place of the two updates.
Obviously test in dev first.
In the else clause, you want to have it insert something if the when is false. Here I am just inserting the current before update field contents.
UPDATE DeviceCatalog
SET [OS] = #OS
,[Location] = #Geo
,[Culture] = #Culture
,[Other] = #Other
,[IPAddress] = #IPAddress
,[Lastmodifieddate] =
case when (
#OldGeo is NULL
OR
#OldAddress is NULL
OR
#OldCity is NULL
OR
#OldCountry is NULL
OR
ISNULL(#Geo.STDistance(#OldGeo) / 1000,0) > 50
) then Getdate()
else [Lastmodifieddate]
end
WHERE [UniqueID] = #UniqueID
It might be simple but I been having trouble figuring out.
I have a piece of code(Similar to Below Code) where I am assigning bunch of values to bunch of variables via select, it does the job but when I am running it I am getting result set which is causing my SSMS to crash is there way to avoid this....
DECLARE #Name VARCHAR(100)
DECLARE #LastName VARCHAR(100)
DECLARE #Address VARCHAR(100)
SELECT TOP 1
#Name = Name
#LastName = LastName
#Address = Address
From Person.Address
Where Name = 'Name'
Order By ID
I am using the above code in a loop where I am processing around 3-400K rows and pass this variables to a stored procedure, each top 1 select statement throws a result set causing my SSMS to crash I dont really need the select top 1 values to be displayed, any idea how to get rid of this?....
Any help would be much appreciated.
---As requested below is the code, I have hashed few things but this is what it is and I am running it from Query Analayzer as this is only 1 time process so we dont need SP to be created.

Use a CURSOR to loop thru your rows!

Well as far I understand it ... change the SP code to below and try again ... most probably will work fine

If your not getting an error message and inserting zero rows, than you select statement must not be returning anything.
what does this return?
select *
FROM tblDBUsage
WHERE tblUniquetblStringsMaster_ID = #StringID_from_Master
If you're first stored proc it didn't look like #StringID_from_Master ever got set. That could be your problem.
