Stored Procedure With Bit Datatype

Mar 26, 2008

Hi guys,

I have a table with following columns and records.

Empid Empname Phone Flag

14 Rajan 2143 1
16 Balan 4321 1
22 Nalini 3456 0
23 Ganesh 9543 0

My requirement is when i delete a record based on empid that record's flag should be set to 1 if it is 0.Actually it should not delete. It should update the flag value. If the flag is already 1 for that particular empid then it should remain as it is. After deletion when i issue "select * from table name", the deleted record (update record) should not be displayed. Only the records with the flag value 0 alone should be displayed in the select statement.

Pls provide me the full stored procedure code

Thanx

Calling A Stored Procedure Inside Another Stored Procedure (or Nested Stored Procedures)

Nov 1, 2007

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly.  For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') 
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). 
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Calling A Stored Procedure From ADO.NET 2.0-VB 2005 Express: Working With SELECT Statements In The Stored Procedure-4 Errors?

Mar 3, 2008

Hi all,

I have 2 sets of sql code in my SQL Server Management Stidio Express (SSMSE):

(1) /////--spTopSixAnalytes.sql--///

USE ssmsExpressDB

GO

CREATE Procedure [dbo].[spTopSixAnalytes]

AS

SET ROWCOUNT 6

SELECT Labtests.Result AS TopSixAnalytes, LabTests.Unit, LabTests.AnalyteName

FROM LabTests

ORDER BY LabTests.Result DESC

GO


(2) /////--spTopSixAnalytesEXEC.sql--//////////////


USE ssmsExpressDB

GO
EXEC spTopSixAnalytes
GO

I executed them and got the following results in SSMSE:
TopSixAnalytes Unit AnalyteName
1 222.10 ug/Kg Acetone
2 220.30 ug/Kg Acetone
3 211.90 ug/Kg Acetone
4 140.30 ug/L Acetone
5 120.70 ug/L Acetone
6 90.70 ug/L Acetone
/////////////////////////////////////////////////////////////////////////////////////////////
Now, I try to use this Stored Procedure in my ADO.NET-VB 2005 Express programming:
//////////////////--spTopSixAnalytes.vb--///////////

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim sqlConnection As SqlConnection = New SqlConnection("Data Source = .SQLEXPRESS; Integrated Security = SSPI; Initial Catalog = ssmsExpressDB;")

Dim sqlDataAdapter As SqlDataAdapter = New SqlDataAdaptor("[spTopSixAnalytes]", sqlConnection)

sqlDataAdapter.SelectCommand.Command.Type = CommandType.StoredProcedure

'Pass the name of the DataSet through the overloaded contructor

'of the DataSet class.

Dim dataSet As DataSet ("ssmsExpressDB")

sqlConnection.Open()

sqlDataAdapter.Fill(DataSet)

sqlConnection.Close()

End Sub

End Class
///////////////////////////////////////////////////////////////////////////////////////////

I executed the above code and I got the following 4 errors:
Error #1: Type 'SqlConnection' is not defined (in Form1.vb)
Error #2: Type 'SqlDataAdapter' is not defined (in Form1.vb)
Error #3: Array bounds cannot appear in type specifiers (in Form1.vb)
Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)

Please help and advise.

Thanks in advance,
Scott Chang

More Information for you to know:
I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly.
I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.

SQL Server 2014 :: Embed Parameter In Name Of Stored Procedure Called From Within Another Stored Procedure?

Jan 29, 2015

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?

CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete]
@QQ_YYYY char(7),
@YYYYQQ char(8)
AS
begin
SET NOCOUNT ON;
select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],

System Stored Procedure Call From Within My Database Stored Procedure

Mar 28, 2007

I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.

How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?

Thanks in advance

Ad Hoc Query Vs Stored Procedure Performance Vs DTS Execution Of Stored Procedure

Jan 23, 2008



Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio

What could explain this?

Obviously,

All three scenarios are executed against the same database and hit the exact same tables and indices.

Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).

The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

Numeric Datatype To Ssis Variable Datatype Conversion Problem

Apr 24, 2008



Good afternoon,

I have an issue with an ssis variable datatype.

The scenario is as follows:

I have a stored procedure:


PROCEDURE [dbo].[sp_newTransaction]



@sourceSystem varchar(50),

@txOut NUMERIC(18,0) OUTPUT

AS

insert into scn_transaction (sourceSystemName) values(@sourceSystem);

SELECT @txOut = @@identity


Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).

I execute the stored proc with the following sql with an OLE DB connection manager:

exec sp_newTransaction ?, ?

The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:

User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1

The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.

At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.

I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.

Thanks much,

B

Exec Twp Stored Procedure In A Main Stored Procedure

Apr 29, 2004

Hi there

i have a stored procedure like this:

CREATE PROCEDURE SP_Main

AS
SET NOCOUNT ON

BEGIN TRANSACTION

exec SP_Sub_One output

exec SP_Sub_Two output


IF @@ERROR = 0
BEGIN
-- Success. Commit the transaction.
Commit Tran
END
ELSE
Rollback Tran

return
GO


now the problem is, when i execute the stored procedure's inside the main stored procedure, and these sub sp's has an error on it, the main stored procedure doesnt rollback the transation.

now i can put the "begin transation" in the two sub stored procedure's. The problem is

what if the first "SP_Sub_One" executed successfully, and there was error in "SP_Sub_Two"

now the "SP_Sub_One" has been executed and i cant rollback it... the error occured in the
"SP_Sub_Two" stored procedure ... so it wont run ... so there will be error in the data

how can i make a mian "BEGIN TRANSACTION" , that even it include the execution of stored procedure in it.

Thanks in advance

Calling A Stored Procedure Or Function From Another Stored Procedure

Mar 2, 2007

Hello people,

When I am trying to call a function I made from a stored procedure of my creation as well I am getting:

Running [dbo].[DeleteSetByTime].

Cannot find either column "dbo" or the user-defined function or aggregate "dbo.TTLValue", or the name is ambiguous.

No rows affected.

(0 row(s) returned)

@RETURN_VALUE =

Finished running [dbo].[DeleteSetByTime].

This is my function:

ALTER FUNCTION dbo.TTLValue

(

)

RETURNS TABLE

AS

RETURN SELECT Settings.TTL FROM Settings WHERE Enabled='true'

This is my stored procedure:

ALTER PROCEDURE dbo.DeleteSetByTime

AS

BEGIN



SET NOCOUNT ON



DECLARE @TTL int

SET @TTL = dbo.TTLValue()



DELETE FROM SetValues WHERE CreatedTime > dateadd(minute, @TTL, CreatedTime)

END

CreatedTime is a datetime column and TTL is an integer column.

I tried calling it by dbo.TTLValue(), dbo.MyDatabase.TTLValue(), [dbo].[MyDatabase].[TTLValue]() and TTLValue(). The last returned an error when saving it "'TTLValue' is not a recognized built-in function name". Can anybody tell me how to call this function from my stored procedure? Also, if anybody knows of a good book or site with tutorials on how to become a pro in T-SQL I will appreciate it.

Your help is much appreciated.

Execute Stored Procedure From Stored Procedure With Parameters

May 16, 2008

Hello,
I am hoping there is a solution within SQL that work for this instead of making round trips from the front end. I have a stored procedure that is called from the front-end(USP_DistinctBalancePoolByCompanyCurrency) that accepts two parameters and returns one column of data possibly several rows. I have a second stored procedure(USP_BalanceDateByAccountPool) that accepts the previous stored procedures return values. What I would like to do is call the first stored procedure from the front end and return the results from the second stored procedure. Since it's likely I will have more than row of data, can I loop the second passing each value returned from the first?
The Stored Procs are:
CREATE PROCEDURE USP_DistinctBalancePoolByCompanyCurrency
@CID int,
@CY char(3)
AS
SELECT Distinct S.BalancePoolName
FROM SiteRef S
INNER JOIN Account A ON A.PoolId=S.ID
Inner JOIN AccountBalance AB ON A.Id = AB.AccountId
Inner JOIN AccountPool AP On AP.Id=A.PoolId
Where A.CompanyId=@CID And AB.Currency=@CY

CREATE PROCEDURE USP_BalanceDateByAccountPool
@PoolName varchar(50)
AS
Declare @DT datetime
Select @DT=
(Select MAX(AccountBalance.DateX) From Company Company
INNER JOIN Account Account ON Company.Id = Account.CompanyId
INNER JOIN SiteRef SiteRef ON Account.PoolId = SiteRef.ID
Inner JOIN AccountBalance AccountBalance ON Account.Id = AccountBalance.AccountId
WHERE SiteRef.BalancePoolName = @PoolName)
SELECT SiteRef.BalancePoolName, AccountBalance.DateX, AccountBalance.Balance
FROM Company Company
INNER JOIN Account Account ON Company.Id = Account.CompanyId
INNER JOIN SiteRef SiteRef ON Account.PoolId = SiteRef.ID

Stored Procedure In Database X, Executes Stored Procedure In Database Y, Wrapped In Transaction?

Jul 20, 2005

Is it possible to execute a stored procedure in one database, which thenitself executes a stored procedure from another database? We have decide tosplit our data into a tree structure (DB1) and data blobs (DB2) (we areusing MSDE and we have a 2gb limit with each DB so we've done it this wayfor that reason). I would like to, say, execute a stored procedure in DB1,passing in the data blob and other details, DB1 will create a tree node inDB1 and then add the blob record to DB2. DB1 will wrap in a transaction ofcourse, as will DB2 when it adds the blob. Is this possible?
