Issue with Temp tables in SSIS 2012 with RetainSameConnection=true

Hello,
We have few packages written in 2008 and are being upgraded to 2012. Our package mostly uses temp tables during the process. During initial migration, we faced issue with handling temp table in the OLE Db destination provider and found a solution for
the same under
usage of Temp tables in SSIS 2012
Most of our packages execute fine now.
we came across a different issue recently. For one of our package, which merges 3 feeds into a temp table and then executes a stored procedure for processing, the package fails intermittently.
Below are properties of SSIS and its components, which you might be interested
* Retainsameconnection for the OLE Db connection manager set to True
* properties of OLEDB Destination
AccessMode : SQL Command
CommandTimeOut : 0
SQLCommand : Select * from #tmp
* using SSIS 2012 and SQL OLEDB Native Provider 11 (Provider=SQLNCLI11.1)
* one of the feed is 10MB
During investigation using profiler, found that though I use RetainSameConnection, I often could see that more than one SPId is used during the scope of SSIS execution and when ever this happens, package fails with below error message
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80040E14 Description: "Statement(s) could not be prepared.".
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80040E14 Description: "Invalid object name '#tmp'."
Now, Why SSIS uses a different SPId during its execution when RetainSameconnection is set to True (note : I have only one OLEDB connection in that package)?
To simulate the issue, Instead of 10MB file, I used a 500KB file and execute the package twice and all went fine.
Is it because of 10 MB file taking long time to process causing the time out of that OLEDB destionation forcing the SSIS to go for another connection? but remember, CommandTimeout is set to infinite(0) for that OLEDB destination.
Much appreciated your response.

Hey,
I understand you used Retainsameconnection property true for all the OLEDB connections you used in the package if not make sure its for all the connection including file connection as well.
Additionally, you can try to set Delayvalidation property to true for all the dataflows and control flows in the connection and try running the package for 10MB file.
I hope this will fix the intermittent failure issue you are facing with SSIS.

Usage of Temp tables in SSIS 2012

Hello,
We have many SSIS packages (2008 R2) which imports data to a temp table and process it from there.
We are upgrading to SQL server 2012 and facing the issue with temp table as working table and our ssis packages fail in 2012. While investigating found that SQL Server 2012 deprecates FMTONLY option
and instead uses
sp_describe_first_result_set , which does not support using of temp tables as import table. SSIS works fine in our workstations but not in the DEV box. With SQL 2012, I can execute from my workstation, which has (11.0.2100.60) where as DEV server
has SQL Server version 11.0.3000.0
Also when I ran profile with that of the DEV box, it gives two different statements
from workstation (11.0.2100.60)
CREATE TABLE #temp (
Id varchar(255) NULL,
Name varchar(255) NULL )
go
declare @p1 int
set @p1=NULL
declare @p3 int
set @p3=229378
declare @p4 int
set @p4=294916
declare @p5 int
set @p5=NULL
exec sp_cursoropen @p1 output,N'select * from #temp',@p3 output,@p4 output,@p5 output
select @p1, @p3, @p4, @p5
go
it works fine
But with the DEV server (version 11.0.3000.0), it executes the below sql and it fails to get the meta data
CREATE TABLE #temp (
Id varchar(255) NULL,
Name varchar(255) NULL )
exec [sys].sp_describe_first_result_set N'select * from [dbo].[#temp]'
On checking the assembly difference between the versions, I could only see Microsoft.SqlServer.ManagedDTS.dll being 11.0.3000.0, which I replace by 11.0.2100.60 version. but still getting the same result.
The other different I found is with ,Net framework libraries.
Could you advise whats the assembly causing this issue between our workstation and DEV server i.e 11.0.2100.60 and 11.0.3000.0
Many thanks

Scripts are taken from profiler.
The error message is
The metadata could not be determined because statement 'Select * from #branchscan' uses a temp table.
I could see the work around saying use of table variable and global temp tables. We are having around 100+ ssis packages which uses temp table for loading the data from a flat file and respective SP to process the data from the temp table. above
error is thrown during the pre-execute phase of the OLE db Destination, when trying to get the meta data of the table.
At this stage, it would be difficult for us to change the logic to global temp or TVP
Thanks

Global Temp Table Not found - SSIS

I am facing below error while using global temp table in SSIS.

1) For data connection manager - Retain same connection is set to True
2) Data Flow task - Delay Validation is set to True
3) Destination Task - Using Temp Table - ValidateExternalMetadata is set to false.
4) I am just using one data connection.
5) before using the temp file I am checking if its exits and if yes drp it first and create it.
Not able to understand the reason for failure.

How to use temp table/variable

Hello,
It's SQL 2008 R2. I need to bring data from Oracle using .Net Providers/ODBC Data Provider to MS SQL table converting Oracle UTC dates to PST. The source connection type cannot be changed as it's given. For the Destination I'm using the OLE DB.
As the truncate all and load could take time I'm trying to use a temp table or a variable to use it further with t-sql merge or not exists to bring/add the only new records to the destination table.
I'm trying different scenarios that is all failed.
Scenario A:
1. In DTF after OLE DB Source I'm using the Derived Colum to convert dates. It's working well.
2. Then use Recordset Destination with an object variable User::obj_TableACD. It's also working well.
3. Then I created a string variable with a simple query that I could modify later "select * from " + (DT_WSTR,10)@[User::obj_TableACD] trying to get data from the recordset object variable but it's not working.
Scenario B:
1. Created a store procedure to create a temp table.
2. Created a string variable to execute SP str_CreateTempTable: "EXEC dbo.TempTable". It's working well with the SQL Task with SQLSourceType as Variable.
3. Then how to populate the temp table from the Oracle source to bring data into the Destination?
I could spend another few days to figure it out. So, please help me on it if there is a way to solve it.
Thanks

Thank you so much, Nitesh. Now, I got the understanding of temp tables in SSIS. However, in my case to implement t-sql merge or not exists to bring the new records only I'd need to load at least a one table into a temp table anyway. So, why not to use a
destination table instead. I also noticed a one remark from the article you suggested that the expert who wrote the article had never actual used the temp tables in SSIS.
So, I decided to go with truncate, drop keys, derive columns, load, and create keys again in the destination table.
Thank you again, I'll reserve the knowledge I got for the temp SSIS tables for some other cases.

SSIS package takes longer time when inserting data into temp tables

querying records from one server and inserting them into temp tables is taking longer time.
are there any setting in package which enhance the performance .

will local temp table (#temp ) enhance the performance ..
If you're planning to use # tables in ssis make sure you read this

Transfer temp table data to excel

there are temporary tables in db. (Sales) . it contains huge data with some columns in being Chinese character .
can in transfer data from temp table to excel through ssis..
example :
select * from #sales
o/p : should be moved to excel .

You can't use a local temp table (whose name starts with #) as a OLEDB source directly at development time because the table will only exist at run time. The SSIS will give you an error similar to "Table/Object not found" at development time.
The workaround would be to use an actual physical table during the package development. A global temp table (whose name starts with ##) created in a different session e.g. SSMS, can also be used but the session that created the global
temp table has to be kept open during the development of the SSIS package. As you might be aware that the global temp tables are available till there is a connection using it.
After the development and testing is complete, stop the package execution and change the table name to a local temp table either in the package UI or the package XML and save the package.

Multiple users accessing the same data in a global temp table

I have a global temp table (GTT) defined with 'on commit preserve rows'. This table is accessed via a web page using ASP.NET. The application was designed so that every one that accessed the web page could only see their data in the GTT.
We have just realized that the GTT doesn't appear to be empty as new web users use the application. I believe it has something to do with how ASP is connecting to the database. I only see one entry in the V$SESSION view even when multiple users are using the web page. I believe this single V$SESSION entry is causing only one GTT to be available at a time. Each user is inserting into / selecting out of the same GTT and their results are wrong.
I'm the back end Oracle developer at this place and I'm having difficulty translating this issue to the front end ASP team. When this web page is accessed, I need it to start a new session, not reuse an existing session. I want to keep the same connection, but just start a new session... Now I'm losing it.. Like I said, I'm the back end guy and all this web/connection/pooling front end stuff is magic to me.
The GTT isn't going to work unless we get new sessions. How do we do this?
Thanks!

Thanks!You may want to try changing your GTT to 'ON COMMIT DELETE ROWS' and have the .Net app use a transaction object.

Temp Tables - Best Practice

Hello,
I have a customer who uses temp tables all over their application.
This customer is a novice and the app has its roots in VB6. We are converting it to .net
I would really like to know the best practice for using temp tables.
I have seen code like this in the app.
CR2.Database.Tables.Item(1).Location = "tempdb.dbo.[##Scott_xwPaySheetDtlForN]"
That seems to work, though i do not know why the full tempdb.dbo.[## is required.
However, when i use this in the new report I am doing I get runtime errors.
i also tried this
CR2.Database.Tables.Item(1).Location = "##Scott_xwPaySheetDtlForN"
I did not get errors, but I was returned data i did not expect.
Before i delve into different ways to do this, i could use some help with a good pattern to use.
thanks

Hi Scott,
Are you using the RDC still? It's not clear but looks like it.
We had an API that could piggy back the HDBC handle in the RDC ( craxdrt.dll ) but that API is no longer available in .NET. Also, the RDC is not supported in .NET since .NET uses the framework and RDC is COM.
Work around is to copy the temp data into a data set and then set location to the data set. There is no way that I know of to get to the tempdb from .NET. Reason being is there is no CR API to set the owner of the table to the user, MS SQL Server locks the tempdb to that user has exclusinve rights on it.
Thank you
Don

Difference between Temp table and Variable table and which one is better performance wise?

Hello,
Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
Which one is recommended to use for better performance?
also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
Is that Table variable using Memory or Disk space?
Thanks Shiven:) If Answer is Helpful, Please Vote

Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
But it also depends upon specific scenarios you are dealing with , can you share it?

Benefit and limitation of temp table in sql server 2008

I have a datagrid in front end of asp.net . when user select a row it shows another gridview (multiple row ) where user have to put some data. when user click CLOSE button i have to keep all data of 2nd gridview in reference with 1st gridview row id.
Same process for each row of 1st gridview. If i will keep all the record in a datatable in view state and finally save the data in database table when final save is clicked then the process may be very slow due to large data in view state. So i think to store
data in temp datable in database for each CLOSE click. For this porpose which temp table i should use
1. Local temporary tables
2. Global temporary tables
3. Normal tables.
Multiple user may do the same thing same time. Please help me.
Thanks

>1. Local temporary tables
>2. Global temporary tables
>3. Normal tables.
When used in stored procedures, local temporary tables (#table) are automatically multi-user.
For global temp (##table) & normal tables, you need to develop your own mult-user logic.

Table or Object type - like #temp table in SQL Server

Hi
I need to create a temp table to hold certain data and then validate. What is the best way to do this oracle. Something similar to #temp tables in SQL Server.
Thanks

IN Oracle, you create the temporary table once, before you start your program. Then anyone can use that definition, but the system keeps the data isolated to eachr/session.
The difference in using Oracle: all DDL, including creating temp tables, performs commits and aquires locks that you want to avoid. It creates unnecessary serialization, causes transactional consistency issues and puts Oracle's Read Consistent model at risk (of ORA-01555 errors).
So, you (or the DBA) would "CREATE GLOBAL TEMPORARY TABLE ..." with the appropriate definition you want, and indicate whether you want the data deleted on commit, or on logoff.
Then you write your procedure, similar to the way you would do it in SQL Server, but you would not bracket it with creating/dropping the temp table - no need.

Inserting data in global temp table?

Hello experts,
i have a form having base table master and detail. i can insert upadate the records.
requirement: creating the global temp table for same form. sothat data save only form session.
for this i created 2 global temp table having same structure required for same form.
i changes the property for block as base table to global temp table.
now i am trying to save the records but not going in the temp table. as i changes the block base table property to temp tables
as well as advance data block properties also .
please tell me the reason? where can be the problem.
thanks yash
Edited by: yash_08031983 on Apr 16, 2012 1:27 AM

i am trying to save the records but not going in the temp table.How do you check that? You cannot go to sqlplus and check if there are any records in the GTT. Data in a GTT is only visible in the current session (= only in the form).
What is the use of a GTT here? What are you trying to achieve?

How to read the data file and write into the same file without a temp table

Hi,
I have a requirement as below:
We are running lockbox process for several business, but for a few businesses we have requirement where in we receive a flat file in different format other than how the transmission format is defined.
This is a 10.7 to 11.10 migration. In 10.7 the users are using a custom table into which they are first loading the raw data and writing a pl/sql validation on that and loading it into a new flat file and then running the lockbox process.
But in 11.10 we want to restrict using temp table how can we achieve this.
Can we read the file first and then do validations accordingly and then write to the same file and process the lockbox.
Any inputs are highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.

Hello Gurus,
Let me tell you about my requirement clearly with an example.
Problem:
i am receiving a dat file from bank in below format
105A371273020563007 07030415509174REF3178503 001367423860020015E129045
in this detail 1 record starting from 38th character to next 15 characters is merchant reference number
REF3178503 --- REF denotes it as Sales Order
ACC denotes it as Customer No
INV denotes it as Transaction Number
based on this 15 characters......my validation comes.
If i see REF i need to pick that complete record and then fill that record with the SO details as per my system and then submit the file for lockbox processing.
In 10.7 they created a temporary table into which they are loading the data using a control file....once the data is loaded into the temporary table then they are doing a validation and updating the record exactly as required and then creating one another file and then submitting the file for lockbox processing.
Where as in 11.10 they want to bypass these temporary tables and writing it into a different file.
Can this be handled by writing a pl/sql procedure ??
My findings:
May be i am wrong.......but i think .......if we first get the data into ar_payments_interface_all table and then do the validations and then complete the lockbox process may help.
Any suggestions from Oracle GURUS is highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.
