0) We are migrating data from SQL Server 2000 OLTP design to SQL Server 2005 OLAP design.
1) We have an data flow task SSIS package.
2) We managed to send a mail with various variables & their values in subject or body of mail.
3) How do we send mail with details of Error/Warning using OnError/OnWarning events?
4) Can we have bad tables i.e where records which failed to migrate get inserted into. If yes, what are the steps to implement this.
5) Can we have a mix of in-built & custom logging. Is logging provider necessary to do logging. What logging provider to use?
6) Where are the errors that come during build, deploy, install and execute stored? Is there a log file(s) & what it their location?
7) Please post links if that is better.

Hi, I don't use SQL much but I need to know how to form the following query against a SQL table. I have a single table with two columns - CurrentPage and LastPage.
I need to write SQL to perform a number of iterations of a particular insert into another table, depending upon the count from CurrentPage to LastPage i've put the following Pseudocode together, but need help implementing this.
Declare counter
Set counter = currentpage
If counter > lastpage
Goto task exit loop
Else perform task - (insert string into table)
Increment counter and loop
I've been playing / reading up, but i'm getting nowhere fast -
DECLARE @Count int
DECLARE @Current string
DECLARE @Last string
SET @Current= dbSL.tblPaging_colCurrentPage
SET @Count= dbSL.tblPaging._colPagingCount
SET @Last= dbSL.tblPaging._colLastPage
WHILE @Count <= dbSL.tblPaging._colLastPage
BEGIN
PRINT 'Hello World'
SET @Count = @Count +1
END
Any help much appreciatted.
Thanks

I have a couple questions about replication (for both 2000 and 2005 servers):
1. which system tables/dmvs/system sprocs can I look at to determine which columns of a table are being replicated?
2. which system tables/dmvs/sprocs can I call to get metadata about publishers and subscribers?
Thanks!

Hi everyone,
I'm just a newbie with clustering.
We've got a 64-bit A-P cluster running with Sql25k 64-bit too.
Each node own two local network adapters. One of them (the one currently is Active) own three IP and the another one only one.
Why? From CLUADMIN I see as one of these three is set as Cluster IP Address in Active Resources. So I see the following configuration for the Active node:
Adapter 1: IP public for Active Directory
Adapter2: IP1 (reserved or ???????)
IP2 (used as SQL IP Address 1 in Active Resources)
IP3 (used as Cluster IP Address in Active Resources)
Passive node:
Adapter 1: IP public for Active Directory
Adapter2: IP (only have one ???)
Is this correct/necessary? Does anyone have similar configuration?
Thanks for your time,

Hello
I have a windows application that connects to a SQLExpress database hosted on a shared server. The client machines will run an interface software and interact with the info within SQL The SQL database isn't huge (50 megs) and all of the info is text. The interface application isn't too complex either, it was designed using VB.net05. I have a few setup questions:
1 - Is it best to use Windows or SQL authentiaction? Currently I am using Windows authentication and I have a user group setup on the DNS that is setup as a user for the SQL database. That has worked so far, but I've only had a few users logged in at one time so far. My plan was to add all DNS accounts that will use the software to the DNS user group, thus giving them access to the SQL database.
2 - I know this gets asked a TON, but I am interested in knowing how many users I should be able to support using the current setup. I have the one user acount setup for the DNS user group. The SQL table is not huge and it is all reading and writing text. The server is running Windows Server 03 and is a couple years old (not sure of exact specs).
Thanks for any help, I am still learning my way around SQL and it's great to have such a vast amount of support for the product.
Happy New Year!

Hi,
I have the hierarchy of packages..
there are three levels..
first package (say L1) calls two child packages.(say L2_1 , L2_2)
the parameters are passed to L2_1 from L1 and it executes completely and successfully.
next step is L1 calls L2_2 without any parameters.. and package fails with error as execution of L2_2 failed.
when I executed L2_2 individually it successfully executes.
L2_2 itself calls 5 other packages (at level 3)..
Am not able to identify the possible reason for failure..

Hi,
I am stuck with a design related issue in SSIS.
Any help would be greatly appreciated.
We do have a HTTP Connection object in SSIS. This implies that we may also be able to use some task to send a web request and receive a web response from a remote server. Can we use any tasks in SSIS to send/receive web requests.
I am aware that we could write code in the Script task to send the web request and receive the response. With the script task, i have another issue. I must refer to a DLL through the code and I am not sure how to use a referenced DLL in the script task.
Once again, thanks in advance for your help.

Hi,
I was wondering if anyone know how to do Dynamic Properties Tasks in SSIS? And, does anyone know how to create a global database in SSIS so I won't have to change all of the database names in my package? I'm sorry, I'm new to SSIS and I'm just really frustrated. Thank you.

Hello,
I realize that I am confused about SSIS and security.
In BIDS, I work on and modify my packages. That part I understand. Then, I want to build my project, then deploy to SQL Server 2005. I know how to do that too (for the most part, please see below):
My confusion arises around the "Protection Level" options in the package properties. Right now I have everything set to "EncryptSensitiveWithUserKey". My understanding is that I need to change this in order to run my packages from SQL Server jobs, because only the creator of the package can currently run the job.
So my question is, since I want to deploy to SQL Server, don't I want to change the "Protection Level" to "ServerStorage"?
However, it will not let me change the protection level to ServerStorage. It says "The protection level, ServerStorage, cannot be used when saving to this destination"... presumably because it is attempting to save to the file system.
However, even when I built out my packages and saved to SQL Server, I could not change the protection level either.
Which is why I am really confused... Once you save your packages to SQL Server, how do you make changes to the packages, so that the changes are reflected in the packages stored on SQL Server?
There is some concept I am not understanding here.
Thanks for any help

Please write YES/NO against point number in your answer i.e. for example:
1) YES, 2) YES, 3) NO, 4) YES etc.
We have source SQL Server 200 databases in one instance and target SQL Server 2005 in another instance both being on different windows 2000 server systems.
Target OLAP DB design is derived from source OLTP.
Most master & transaction tables are as is but some target tables are a result of merging source tables.
We need to do SSIS packages based migration using data flow task based on column mapping & queries using Business Intelligence Development Studio (BIDS). There are no transformations required.
1) Can I group packages under project into sub-groups i.e. super packages?
2) Can I execute a set of packages together which are logically/physically grouped?
3) Can we execute set of ordered packages/individual packages from command line and even
stored procedure?
4) Can we maintain transaction integrity across the entire set of ordered packages we execute?
5) Can we send a mail to mail id(s) in case of events like OnError etc.
6) Can we schedule the packages?
7) Does SSIS provide via BIDS a way to compare data in source with target to decide what got
inserted/deleted/updated and based on that do the necessary?
8) Can SSIS packages be developed including code for data encryption?
9) Can we pass parameters to packages that get called from stored procedure?
10) Can we call stored procedure/function in SSIS package?

I have been working with SSIS and find myself stopped on what seem like very basic tasks.
Am I right in thinking that, if you want to import a flat file into a SQL datatable, in most PC based systems, that you have to manually cast EVERY SINGLE COLUMN to unicode string, if you don't want to get the 'cannot convert between unicode and non-unicode string data types'? I mean, this is surely a VERY COMMON task, taking a CR/LF delimited ASCII file and dumping it into a database tables? What if you have 50 fields to import?
Am I the only one who finds it very difficult to cast a string from a textfile to a date format? At this point, I always just dump the date to a 8 character string and save it that way, and use a SQL view to cast it to a date. At least SQL Server can do 'basic date conversions'. Is there any way to freeze execution and find out what data was provided to a derived column, if you're trying to do some substring operations and hodge together a date? I couldn't find any. I usually put a extra column in a datatable and plunk some data there to find out 'what it looked like', how else can you debug an SSIS program?
Is there a planned service pack or update to SSIS that will make this more usable? Does Microsoft ever intend to implement an UPSERT type module? Or a File Move operation that handles directories that fill up with log files, each of which have to be added to a datatable and then moved to an archive directory (surely, another very common task - I figured out how to accomplish this but it is far from intuitive, the way it currently works). Sorry for grumbling, but honestly, I find turnaround time to develop a very simple import program is RIDICULOUS. It's quicker to write a COBOL program to issue a bunch of formatted SQL UPDATE statements than using this application.

I am using SSIS with Transaction, and I met a lot of questions as below:
1.IF DTC doesn't support ADO.NET Connection?
Please check the ADO.net Connection's property, it has a property named like: DTCTrancactionSupport. But it's always set to False and unable to edit.
IF the answer is NO, HOW could I bound all my Tasks into one Transaction? You know, I have some Tasks with SQL connection, and I have also some Script Tasks, witch need the ADO.net connection.
2.IF DTC required to run in both the Destination Server and the Source Server?
I have a Dataflow Task, and take some data from a table in a Source Server to a Destination Server. The DTC doesn't run on the Source Server. I found the Dataflow Task hangs when I use the SSIS Transaction(just set the Task's transactionOpion to Required, Only one Task in the Package).
3.IF DTC doesn't support RetainSameConnection?
Many people say that. Really?
4.When a DTC transaction is running, if the table in it could not be modified by process outside of the transaction? For example, a package with a DTC transaction, and there is a SQL Task inside, when it is running, could I modified the same table's data manually(in the Sql Sever Management Studio)?

Hello all, this is my first post, I have a couple of basic questions regarding the use of SSIS. I have used SSIS for a couple of years for on off table loads but never implemented production jobs with it so please bear with these questions.
1. When making scripts that connect to one or more databases, is there a way to store the userid and password somewhere besides embedded within the package, such as a web.config file, this would make routine password changes much more manageble.
I guess it was only one question but any help would be greatly appreciated.
Thanks.

I have a some raw data in a string that looks like
'1989'
I need that to become numeric 19.89
if I define a type double for rawAmount
and do this:
rawAmount = CInt(iRest.Substring(41, 4))
Row.amount2 = rawAmount / 100
where row.amount2 is a type double precision float from my script component task output, I get:
19.899999999999999
what output should i use in this data flow component to get 19.89.
thanks.

The following is a list of questions that I have not been able to obtain concrete answers. I am probably missing something:
1) ReadWriteVariables -- can the updated value for a ReadWriteVariable be accessed within the same data flow? It appears not as I think the PostExecute() fires at the completion of the data flow not the end of the Script Component. Secondarily, the Script Component is a non-blocking transformation so the component does not "see" the end of the pipeline prior to sending data down stream.
2) Record Count -- Because of #1 above, How could you calculate a record count for a data stream? It does not appear that one can calculate the number of records for a data stream within a data flow and then access the count from within the same data flow.
3) FinishOutputs() -- Is the concept of FinishOutputs() applicable to Script Component Destinations? Asked another way, is FinishOutputs() executed at the end of the data stream regardless of whether there are "real" outputs for the component? I can create a "Dummy" output to create FinishOutputs() but is this ok?
4) Script Component -- It appears that the Script Component Source, Transformation or Destination are really defined based on the columns defined in "Inputs and Outputs". Can you convert an Source script component to a transformation script component by simply adding an Output?
Sorry for these basic questions but I am not getting it completely. As you can tell...

Hi thanks for looking at my question
Using sqlServer management studio 2005
My Tables are something like this:
--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]
-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]
--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE
DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39
Well this might look like a very basic error:
I get this Error after trying to delete something from Table €œEmployee€?
The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.
Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €œBranch€? entry, basically each entry in €œbranch€? and €œEmployee€? is child of each other which makes things more complicated.
My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €œON DELETE CASCADE€? or something?
Thanks

Hi,
Is there a format function in MDX which will help me solve the following
scenario:
One of my measures is Net Sales and I have tried all different formats
in Analysis Services so that it shows without the decimal places i.e.
instead of showing the Net Sales for any selected combination of
Dimensions as 123,456.04, I want to show it as 123,456
When I browse the cube (in Analysis Services), I can meet my
requirement. However, in my front-end (Microsoft Data Analyzer), I am
still getting it as 123,456.04 (even when the same in Analysis services,
i.e. when I browse the cube, is being shown as 123,456).
I do not have much choice at the moment and am stuck with Microsoft Data
Analyzer and unfortunately have not been able to solve this :(
Can someone think of a solution/workaround/use of MDX which will help me
get the results being displayed without the decimal. Is there a format function that I can use in MDX and how to use it???
Many TIA

I've been working on a performance review web application (i.e., employee's annual reviews done via the web). In the process of creating the application I've been teaching myself .NET - maybe not the best way to do it but I've been learning a lot. However, I still feel like I'm not doing something right.On each Page_Load I'm doing database work with a data reader: Reading the data in, displaying it, letting the user add, edit, or delete it, etc. So every Page_Load code behind looks like this: string sql = "SELECT UserID, Passwd, RecID, Name FROM UserList";
SqlConnection myConn = new SqlConnection("Server=BART; Database=WSSD; User ID=sa; Password=wss1231");
SqlCommand cmd = new SqlCommand(sql, myConn);
SqlDataReader dr;
myConn.Open();
dr = cmd.ExecuteReader(); And so forth and so on. Now since I re-use this code again and again - I imagine it's a good idea to implement my connection code in a class that I can re-use easily. But I have no idea where to start on something like that. What can I say? I'm a newb. A push in the right direction would be great.

Hi,
I made a DTS which appends data coming infrom a view to an exisiting table.So far no problem and all goes well.
I am facing a problem due to the format of the date that is coming in (getting appended) and while going through BOL, came across the following topic:
mk:@MSITStore:C:Program%20FilesMicrosoft%20SQL%2 0Server80ToolsBookshowtosql.chm::/ht_dts_trns_97ou.htm
I tired the above tips but it appears that if I try to do this in my DTS (which appends data),the logic of the DTS will change. A single arrow also gets added whichI think represents a simple mapping/transformation rather than a append. To clarify my point, please note the attached image which represents that the data is being appended (due to the many sided arrows pointing to the source and destination - visible under the Transformations tab of my DTS).
Sincerely hoping that my post is clear, can someone help me find how to make changes in a DTS (which appends data) and ensuring that thelogic remains the same i.e. it should append data.
Many TIA
