Calling SP From SP
Jan 20, 2004
I'm developing a new Stored Proc that will be taking information in to enter customer and order info. Looking at the current Stored Proc its using alot of If statements and I'm thinking of breaking the sp up into different Stored Procs and calling them all from One main stored proc. I know how to do this but I was wondering how it would effect performance. So should I simply keep all the stuff in one proc or module it out into multiple ones to make it easier to follow and read?
Thanks

Hi all, i have a DTS package that i call from a C# app, i had it working great until i decided to use an activeX script to do the data transformations instead of the row copy. I need to use ActiveX to add a standard name to the last column in the destination table. the problem is the task is executing without errors (from c#) but nothing is happening, its failing silently. If i modify the Data Transformation back to a standard column mapping (with separate DTSTransformations for each column) it works fine, but as soon as i use activeX to handle the transformations it doesn't work. Can anyone tell me what i may be doing wrong. heres the calling code from C# if(f.Name.Substring(13,7).ToLower() == "product")
{
try
{
activity.Log("Starting Product DTS Package...");
DTS.Package2Class package = new DTS.Package2Class();
object pVarPersistStgOfHost = null;
package.LoadFromSQLServer(
"192.168.8.8",
"username",
"thepassword",
Microsoft.SqlServer.DTSPkg80.DTSSQLServerStorageFlags.DTSSQLStgFlag_Default,
null,
null,
null,
(string)ConfigurationSettings.AppSettings["productDTSPackage"],
ref pVarPersistStgOfHost);
package.GlobalVariables.Item(1).Value = f.FullName.ToString();
package.Execute();
package.UnInitialize();
//force release of COM object
System.Runtime.InteropServices.Marshal.ReleaseComObject(package);
package = null;
}
catch(Exception e)
{
activity.Log(string.Format("Failureprocessing {0}",WorkingPath + f.Name) +" - "+ e.Message);
} and the activex i tried to use for the transformations is: '**********************************************************************' Visual Basic Transformation Script'************************************************************************' Copy each source column to the destination columnFunction Main() DTSDestination("Yesmail Id") = DTSSource("product series") DTSDestination("Customer CKM CustId") = DTSSource("product family") DTSDestination("Product SKU") = DTSSource("transaction date") DTSDestination("product model name") = DTSSource("serial number") DTSDestination("serial number") = DTSSource("product model name") DTSDestination("transaction date") = DTSSource("Product SKU") DTSDestination("product family") = DTSSource("Customer CKM CustId") DTSDestination("product series") = DTSSource("Yesmail Id") DTSDestination("fileName") = DTSGlobalVariables("sourceFile").Value <-- this is why im using the activex for this field to get a Global Variable. Main = DTSTransformStat_OKEnd Functionthe weird thing is the PACKAGE runs fine from ENTERPRISE MANAGER with this activex, it just doesn't do it from my Calling app, perhaps i have missed something i need to change in the package constructor? BTW: i do have my assembly signed in C# for the COM wrapper.thanks in advance, mcm

I'm working in SQL Server 2005. I have an existing SP that does exactly what I need (it's the aspnet_UsersInRoles_IsUserInRole SP). I want to reuse this SP and use it's return value as a field in the SP I'm writing. How do I go about doing this? I could take the logic out of the called SP and wrap it in a function; but, I would really like to reuse the SP aspnet_UsersInRoles_IsUserInRole. Thanks in advance for any assistance.

hi,
i'm trying to call a dts package from vb.net.
i got 2 examples which both don't work.
first one gives me a [DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied error.
source code:Dim serverName As String = "SERVERNAME"Dim oPackage As New DTS.Package()Dim oStep As DTS.StepDim pVarPersistStgOfHost As Object = Nothing
oPackage.LoadFromSQLServer(serverName, "USERID", "PASSWORD", DTSSQLServerStorageFlags.DTSSQLStgFlag_Default, _ "DTSPASSWORD", Nothing, Nothing, "DTSPACKAGENAME", pVarPersistStgOfHost)
For Each oStep In oPackage.Steps oStep.ExecuteInMainThread = TrueNext
oPackage.Execute()
Dim err As LongDim source, description, message As StringFor Each oStep In oPackage.StepsIf oStep.ExecutionResult = DTSStepExecResult.DTSStepExecResult_Failure Then oStep.GetExecutionErrorInfo(err, source, description) message = String.Format("ErrorCode: {0}, Source: {1}, Description: {2}", err.ToString(), source, description)Else message = "Success"End IfNext
oPackage.UnInitialize()oPackage = Nothing
second example tries to create a dts package dynamically. this time i get the error that the CustomTask can not be casted, somehting about the QueryInterface.
source code:Dim oPackage As New Package2()Dim oConnection As Connection2Dim oStep As Step2Dim oTask As TaskDim oCustomTask As BulkInsertTask
oConnection = oPackage.Connections.[New]("SQLOLEDB")oStep = oPackage.Steps.[New]()oTask = oPackage.Tasks.[New]("DTSBulkInsertTask")oCustomTask = CType(oTask.CustomTask, BulkInsertTask) <-- error
With oConnection .Catalog = "CATALOG" .DataSource = "SERVERNAME" .ID = 1 .UseTrustedConnection = True .UserID = "USERID" .Password = "PASSWORD"End With
oPackage.Connections.Add(oConnection)oConnection = Nothing
With oStep .Name = "InsertGemal" .ExecuteInMainThread = TrueEnd With
With oCustomTask .Name = "InsertGemal" .DataFile = "D:ImportGemal.dat" .ConnectionID = 1 .DestinationTableName = "Gemal" .FieldTerminator = ";" .RowTerminator = "
"End With
oStep.TaskName = oCustomTask.Name
With oPackage .Steps.Add(oStep) .Tasks.Add(oTask) .FailOnError = TrueEnd With
oPackage.Execute()
oPackage.UnInitialize()oPackage = Nothing
any help highly appreciated!

In my shared hosting environment where I am making large volumes of database calls, I am very anxious to preserve my heavily throttled threads-I presume when I make a database call, that it is going to a separate server and any threads that server may be using are in addition to my " hosting plan ".
My question (s) is, is it therefore a no-brainer to always make calls to:Dim oResult As IAsyncResult = iDBCmd.BeginExecuteReader()arWaitHandles(0) = oResult.AsyncWaitHandleiIndex = WaitHandle.WaitAny(arWaitHandles, 60000, False)
i.e. run all calls to the database asynchronously?
Is it really releasing a thread back to my asp.net App while it is waiting? (I.e. Is it worth doing)

I'm new to using DTS packages and I'm running into a problem. Hopefully someone can help me out. I have an ASP.NET page that needs to call a DTS package. Everything seems to be working right up until I call opkg.Execute. The package seems to run but nothing happens. After further investigation I have found what looks like a permissions issue. this is the message I'm getting"
Error Number:
-2147467259 {Integer}
Error Description:
"The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data." {String}
This is obviously a permissions issue. I'm just not sure who the DTS package is running as and where to set the permissions.
Any ideas????
Thanks

SQL Server Load Balancing -- Any ideas?
There is no inherent mechanism available in SQL Server (replication, log shipping, or clustering) which allows you to load balance you database server.
Clustering is only useful for a failover situation and does not allow active/active balancing.
Is is possible to use merge replication between two identical OLTP servers
and manage transactions via MSMQ? Will this mechanism allow for a load balanced OLTP server?
Will this work? If not, why not?
What will work? Will federated servers work for an entire database??

Dear Everybody,
Hi again!
Supposing I have an SQL Server Function named Fxn1 which returns a VARCHAR(6) value. I want to use this returned value in another function named Fxn2 but Fxn2 accepts a parameter of type INT. Fxn2 itself returns an INT value. This has to be achieved in a single line.
The following line of code will not work in SQL Server. How should I achieve this?
declare @Res INT
EXEC @Res = Fxn2 (CONVERT( INT, Fxn1 ))
Thanx in advance!

I have a rather complex function (part of a production planning engine) that is written in VBA, and is part of my front end app. I'd like to be able to somehow call this function from either a sproc or DTS package in SQL. Is this possible, or am I going to have to convert the function to a SQL sproc (ugh)?

The Scenario:We have some data that can be in three states. One is a saved state,a temporary state, and a complete state.The complete state is the bulk of the data. This data will berequested 1% of the time, maybe even less.The saved state and temporary state will only number 10-15 records.This data will be used 99% of the time, very frequently.So to summarize there will be 10-15 records that will be used ALL thetime…. And 50,000-100,000 that will be used very infrequently.The programmer that I work with wants to combine the tables. I wantto keep the tables sepperate.My logic is that it will be much faster to work with 10-15 recordsthan sift threw 50-100k most of which are unnecessary to 99% of therequests. Also there are frequent deletions/modifications in thetemporary table(10-15 records). The complete table can NOT havemodifications or deletions (50-100k records). The optimization forthese tables is also very different.He says that since the structures are almost identical they should bein the same table, that we should just use a field to denote thedifferent types of records. He insists that my view is wrong and thatI know nothing about databases.I may be new to SQL, but am I really that out to lunch? Would it notmake sense to keep these tables separate?(Thank you for taking the time to read this)Sat

I already post one thread to list all SPs that are starting with sp_.
I found 150 SPs on average for each database.
The next step in my assignment is to find all SP's that are using these SPs.
Here is an example. Lets say I have a procedure that is 'sp_appname' I need to find out all SPs that are using this SP.
For this I wrote following statement.
SELECT name from sysobjects so INNER JOIN syscomments sc
ON so.id=sc.id
WHERE sc.text LIKE '%sp_appname%' AND so.type='P'
Let me know the the above statement will give accurate result. If anybody can make this statement more efficient ....Let me know.
Hope you reply soon.
Thanks,
Pradeep
