Apr 11, 2008Hi,
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.
SSIS And Security - Questions
Mar 15, 2007Hello,
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

SSIS Boolean Questions
Oct 24, 2006Please 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?
SSIS Related Questions
Nov 7, 20060) 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.
Some Basic SSIS Questions
Jan 18, 2008I 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.

SSIS DTC Transaction's HOT Questions
Dec 8, 2006I 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)?
Couple Of Basic SSIS Questions
Dec 4, 2007Hello 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.

Simple Vb / Ssis Data Type Questions
Mar 27, 2007I 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.
Newbie Questions About SSIS Script Components And Data Streams
May 10, 2007The 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...

Two Questions!
Aug 4, 1999I have two questions,
1) Could anyone please point me in the right direction concerning information pertaining to NT Server Enterprise Edition verses NT Server Workstations. We are having problems running SQL Server 7.0 and the Enterprise Edition together on the same machine and was wanting to find information about compatability issues, if there are any,
2) I, on a SQL Server 6.5 database shrunk it by 2 Gb. When I looked to see if SQL Server released those 2 Gb back to the hard drive, I was amazed that it didn't! Did I miss something or will SQL Server 6.5 not release the space because of the initial set-up. And why did SQL Server 6.5 automatically take the space from the Transaction logs when neither of the devices were specified? Is the Transaction Log the default area for shrinkage?
Thanks in Advance!

SQL- TDS - TCP/IP Questions.
Nov 5, 2007Hi, does anyone know how to explain how SQL transactions get mapped into TDS and TDS gets mapped into TCP/IP packets?
Or can you please point me in the right direction? I need to figure out how TDS and TCP/IP relate?
We're using replication and are having some latency issues and I'm trying to find out how SQL handles TDS and TCP/IP etc...
Thanks for your time.
DTS Questions
Feb 7, 20021. When we create DTS in SQL Server through DTS designer, where are they stored physically?
2. What would be the best way to modify a DTS without using DTS designer?
3. Is there any other way to create DTS apart from DTS designer and Visual Basic?
4. Is there any website which has detailed information for DTS? (which has more FAQs like above?)
In our production environment, we keep changing the servers frequently, and everytime that happens, I have to change the connection properties in all the DTS going to them one by one.
thanks,
sanjay.
SQL Questions
May 4, 2001I am not too familiar with SQL Server, but my supervisor gave me the task of finding out the difference between SQL Enterprise and SQL Standard. He also asked me to research the difference between processor licences and client access licences. I will use the Internet as a resource, but I would also like to hear the opinions of someone who uses these programs or is knowledgable about them. So please any suggestions or any useful links would be very helpful.

VDI Questions!
Aug 31, 2004Could I do periodicity backups to another computer(mediaserver) using VDI??
I mean , Could I config a Virtual Device so that I can do backups like disk or tape, I can use
'backup database ...to virtual_device='...' ' to do backup to another computer(mediaserver)?
suppose that I have finished the interface of mediaserver.
If this is impossible,how can I do periodicity backups to another computer??
I have finished a program using VDI that can do backup to another computer,and I know how to do periodicity backups to disk or tape. but I am puzzled about the periodicity backup using VDI.
How should I do?
Thanks,All.

ASP/SQL - Several Questions
Aug 21, 2006Hi
Im relatively new to ASP/SQL and have been thrown into the deep end by work. Ive got courses to go on, but not for another 3-6months.
Ive got an ASP file calling a database using SQL. Once you hit the "go" button, it puts this data into an Excel file, under a new window (still showing the asp file in the address bar).
It currently shows:
1)
Item numbers that end in "0" i.e. 3.10, 12.20 appear as 3.1 and 12.2 respectively in the Bill of Materials … i.e. being treated as decimals … I need them to show-up as text.
************************************************** *******************
2)
When saving the spreadsheet … it would be good to get "X" to set the default file name to:
<Quote ID>_<Customer>_<Platform>_<version>.[xls|pdf]
************************************************** *******************
3)
When a spreadsheet is displayed, it is in an editable Excel format.
Is it possible to lock the file automatically when its opened or password protect it?
************************************************** *******************
4)
If a spreadsheet window is open and you try and open a new one, the old one pops-up/is still there. Need to be able to close the old one and re-open a new one automatically.
If necessary i will post the code.
Any takers?
Thanks

I tried to sort by date and the only way was to use the serail numberinstead of the litteral nameI tried SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003"but this does not work.I then tried SELECT * FROM [Sheet1$] Where [Date] <= 37822" and itworks.Do you know a way to use 07/20/2003?2. I need to sort my data twice, first by name and second by date. Is itpossible to sort twice in one query?Something like:"SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003 ORDER BY [NAME] ASC,ORDER BY [DATE] DESC"3. Even if the first row of my Excel sheet includes the headers, I cannot perform a query other than SELECT * FROM, for exemple, SELECT [NAME]FROM, does not work. do you know how to do that?Thanks in advance for sharing your experience,Phil*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Aug 14, 2007Hi All,
I was asked couple of questions yesterday and I thought I had to still learn a lot. Questions sound very normal but as for as I am concerned, don't know the answers hence this forum.
Please advise.
Here the questions asked to me
1) A simple insert into the table (could be from .net application or query analyzer) takes 10 minutes and times out, does not do any thing. What could be the reason and how would you identify and resolve the problem.
2) A simple select from table taking 10 minutes( assuming there are only there columns in the table,those are,
id, name, description)
id being identity column and has got index as well. What could be the reason and how would you identify and resolve the problem?
3) How would you change the identity column value or can we change the identity value and how?
4) How would you use the shared, update, exclusive locks in the sql statement.?
Please let me know.
