Losing Temp Tables Between Tasks

Mar 30, 2006

I have a control flow setup with 5 tasks.

1. Create Temp Table (Execute SQL)
2. Load Temp Table (Execute SQL)
3. Data Flow Task using the temp table
4. Data Flow Task using the temp table
5. Drop Temp Table (Execute SQL)

Tasks 3 & 4 are currently setup to run parallel/concurrently - meaning they both branch directly off of task #2. They both also lead to task #5. Also, my connection manager is set to retain its connection.

Here's the problem. When executing this flow, task #3 will sometimes fail, other times it will succeed - without me changing anything between runs (I simply end debugging and run it again). When it does fail it is always because it cannot find the temp table. One thing to note is that task #4 (running at the same time as #3 and using the same temp table) always finishes first because it does quite a bit less work. Last thing to note: if I set up task 4 to run after 3 it works everytime, but of course it takes much longer for the total package to execute.

How is it that the task can find the temp table on some runs, but not on others? If this is just quirky behavior that I am going to have to live with for the time being, is there a way to force a task to re-run X number of times before giving up and moving on?

Thanks,
David Martin

A Curious Error Message, Local Temp Vs. Global Temp Tables?!?!?

Nov 17, 2004

Hi all,

Looking at BOL for temp tables help, I discover that a local temp table (I want to only have life within my stored proc) SHOULD be visible to all (child) stored procs called by the papa stored proc.

However, the following code works just peachy when I use a GLOBAL temp table (i.e., ##MyTempTbl) but fails when I use a local temp table (i.e., #MyTempTable). Through trial and error, and careful weeding efforts, I know that the error I get on the local version is coming from the xp_sendmail call. The error I get is: ODBC error 208 (42S02) Invalid object name '#MyTempTbl'.

Here is the code that works:SET NOCOUNT ON

CREATE TABLE ##MyTempTbl (SeqNo int identity, MyWords varchar(1000))
INSERT ##MyTempTbl values ('Put your long message here.')
INSERT ##MyTempTbl values ('Put your second long message here.')
INSERT ##MyTempTbl values ('put your really, really LONG message (yeah, every guy says his message is the longest...whatever!')
DECLARE @cmd varchar(256)
DECLARE @LargestEventSize int
DECLARE @Width int, @Msg varchar(128)
SELECT @LargestEventSize = Max(Len(MyWords))
FROM ##MyTempTbl

SET @cmd = 'SELECT Cast(MyWords AS varchar(' +
CONVERT(varchar(5), @LargestEventSize) +
')) FROM ##MyTempTbl order by SeqNo'
SET @Width = @LargestEventSize + 1
SET @Msg = 'Here is the junk you asked about' + CHAR(13) + '----------------------------'
EXECUTE Master.dbo.xp_sendmail
'YoMama@WhoKnows.com',
@query = @cmd,
@no_header= 'TRUE',
@width = @Width,
@dbuse = 'MyDB',
@subject='none of your darn business',
@message= @Msg
DROP TABLE ##MyTempTbl

The only thing I change to make it fail is the table name, change it from ##MyTempTbl to #MyTempTbl, and it dashes the email hopes of the stored procedure upon the jagged rocks of electronic despair.

Any insight anyone? Or is BOL just full of...well..."stuff"?

Importing/Exporting Tables - Losing Identity

Oct 1, 2007

Hello,

I'm fairly new to MS SQL & I have a problem copying tables from one d/b to another. When I do an import or export select Copy tables, the tables & the data get transferred, but all the Identities are set to NO. My D/Bs have 188 tables & it's a pain to reset all of them manually.

Is there a setting I don't know about that will transfer the tables & maintain the Identity?
(I'm using SQL Server Management Studio 9.0)

Temp Tables Vs Temp Variables

Jul 20, 2005

I have an application that I am working on that uses some small temptables. I am considering moving them to Table Variables - Would thisbe a performance enhancement?Some background information: The system I am working on has numeroustables but for this exercise there are only three that really matter.Claim, Transaction and Parties.A Claim can have 0 or more transactions.A Claim can have 1 or more parties.A Transaction can have 1 or more parties.A party can have 1 or more claim.A party can have 1 or more transactions. Parties are really many tomany back to Claim and transaction tables.I have three stored procsinsertClaiminsertTransactioninsertPartiesFrom an xml point of view the data looks like this<claim><parties><info />insertClaim takes 3 sets of paramters - All the claim levelinformation (as individual parameters), All the parties on a claim (asone xml parameter), All the transactions on a claim(As one xmlparameter with Parties as part of the xml)insertClaim calls insertParties and passes in the parties xml -insertParties returns a recordset of the newly inserted records.insertClaim then uses that table to join the claim to the parties. Itthen calls insertTransaction and passes the transaction xml into thatsproc.insertTransaciton then inserts the transactions in the xml, and alsocalls insertParties, passing in the XML snippet

Temp. Tables / Variables / Process Keyed Tables ?

I have 3 Checkbox list panels that query the DB for the items. Panel nº 2 and 3 need to know selection on panel nº 1. Panels have multiple item selection. Multiple users may use this at the same time and I wanted to have a full separation between the application and the DB. The ASP.net application always uses Stored Procedures to access the DB. Whats the best course of action? Using a permanent 'temp' table on the SQL server? Accomplish everything on the client side?

DTS - SP And Temp Tables

Nov 3, 2000

I am attempting to execute a stored procedure as the sql query for a data transformation from sql into an excel file. The stored procedure I am calling uses temp tables (#tempT1, #tempT2, etc.) to gather results from various calculations. When I try to execute this sp, I get
'Error Source: Microsoft OLE DB Provider for SQL Server
Error Description: Invalid Object name "#tempT1"'

Is there a way to make a DTS package call a stored procedure that uses temp tables?

Thanks.

##Temp Tables

Jun 16, 2004

I have a stored proc that creates a temporary table, then calls several other stored procs to insert data.


CREATE PROCEDURE usp_CreateTakeoff
@iEstimate int,
AS

CREATE TABLE ##Temp_Takeoff
(
Field1 ......
Field2 ......
)

-- Add Structural data
usp_AddStructural @iEstimateID, 1, 'Structural'
usp_AddForming @iEstimateID, 2, 'Forming'
...
...
...
GO


Now, a couple of problems, after the table is created and populated, I cannot find it in my list of tables, even after "refreshing".

I checked to ensure that it exists using the query analyzer and it does so I know the table is being created.

Also, I cannot see the table using crystal reports, connecting etc...... Can I not access a temporary table from 3rd party applications? I have crystal reports 7.0 professional.

Any ideas?

Temp Tables And UDF's

Dec 14, 2004

Hey,

I am in the process of modifying some stored procedures that currently do not use temp tables. For this modification I am required to make the stored procedures use temp tables. There are several UDF's within this stored procedure that will need to use the temp tables, and this is where in lies the problem. Does anyone know of a work around that would allow UDF's to use temp tables, or does anyone know of alternate methods instead of temp tables that wouldn't involve too much change?

Thanks

Temp Tables

Apr 7, 2006

Hi,

I have a called stored procedure which creates a bunch of temporary tables, inserts data into them, indexes the tables and then returns to the main calling SP. In the main stored procedure I then do SELECTs from the temporary tables. My problem is I keep getting
invalid object errors on the temporary tables:
Invalid object name '#temp_table1'

The stored procedure is in a test environment. In the SELECT I tried a prefix of database owner (my logon) as well as "dbo." but still get the error. Any suggestions as to what I am doing wrong would be much appreciated.

Thanks,

No Temp Tables In SQLDatasource?????

Apr 12, 2006

   Please tell me there's something I haven't set.   I've done several tests now.   If your final return in a stored proc is from a temp table (ala #mytable ) the system cannot read the schema - for that matter, it won't run at all, complaining that the object #mytable doesn't exists.
It can't possible be that temp tables aren't allowed in procs used by SQLDatasource - please tell me what I am doing wrong.
This proc, when fed to a sqldatasource,  fails in the designer with #temp does not exists.
CREATE PROCEDURE dbo.repTest_TempASBEGIN
CREATE TABLE #Temp( [iTestID]  uniqueidentifier, [bTest] [bit], [cTest] [varchar] )
INSERT INTO #TempSELECT *FROM tTest

Temp Tables And Performance

Mar 17, 2001

I have been researching some performance problems in a very large
application and I have a couple of questions about temp tables. (SQL 7.0
SP2)

I have one large procedure that I have been using as a test case.
Originally this procedure was a cursor with lots of processing steps
involving writing to, reading from and deleting in temp tables inside the
cursor. I remember reading that temp tables inside a cursor were a
potential performance problem, so I rewrote the procedure, replacing the
cursor with a While Loop.

Doing this showed no increase in performance. Since Profiler was showing .5
second duration times on statements in the procedure accessing the temp
tables I tested some more. I moved all the create statements to the top of
the procedure, as I know these statements after processing steps can cause
recompiles to happen. Still no performance increase.

Finally I replaced all the temp tables with actual tables, just to see what
would happen. With no other changes the performance increased by more than
500%.

Can someone give me some clues as to what is happening here, because if this
is a symptom of something I don't understand, the potential performance
problems from other places where temp tables are similarly used in the
application are enormous.

Thanks.

Seeing SQL 7.0 ##temp Tables In Access 97

May 2, 2001

The problem is we need local tables in Access for SubReports (can't use store procedures as record source for this), therefore trying to create temp table and link to Access for each report instance.


When we create the ## type table in tempdb this cannot be linked from Access (cannot be seen via DSN).
The only other option we can find is doing
CREATE TABLE tempdb.dbo.[tablename]
but this requires the user to have admin permissions and therefore be 'dbo' on tempdb and not 'guest'.

Any clues?

Testing For Temp Tables

May 11, 2004

Is there any way to test if a table exists in the temp dB. In a procedure I create table called ##Test but I want to test if it exists before it's created and if it does I want to delete it. (It has to be a ## table because it's in a procedure being called in another procedure depending on an IF statement). The reason I want to do this is that I have multiple users and Occasionally they get the ... There is already an object named '##Test' in the database. error

Many Thanks

Global Temp Tables

Aug 11, 1998

Hi everyone:

I am creating an sp, in which I check for the existence of a global temp table (using the exists)
statement. If the Exists returns a false, I move on to processing without the temp table. If it
returns a true, I utilize the temp table to do some inserts. I create the temp table when my
application first starts up. The problem that I am facing is that the check for the temp table`s
existence seems to be failing. Is there any other way to check for the existence of a global
temp table??

Any info really appreciated
Thanks

Temp Tables In Dts Package

Jul 18, 2002

Sql 2000

Hi All,

I am creating a dts package which copies data via transform data task from a sql sever connection to an excel spreadsheet connection.
The transform data task uses a query that goes like this.

create table #temp1(CName varchar(10))

Insert #temp1
select CName from tbl1

--tbl1 is in a user DB called SALES

create table #temp2(VName varchar(10))

Insert #temp2
select CName from #temp1


select * from #temp2

--I need the resultset of the last select statement into an excel spreadsheet.
The problem is I can't even create the dts package..it shows up with an error saying that #temp1 is an invalid object....I am guessing that since the default database for the transform data task has been selected as SALES it is trying to locate the the #temp1 or #temp2 table in that DB instead of looking in the TEMPDB....My question is..is there any workaround for this problem.

Sample code welcome!!!!

Any help appreciated !

TIA

Help With A SQL Query Using Temp Tables

Aug 30, 2004

Hi All,

I have 4 temporary tables that hold criteria selected through a report wizard.
I've created a SQL statement and used the four tables in my WHERE/ AND clauses but the results retuned are not being filtered correctly.

Would somebody be kind enough to help me out please.

To briefly summarise, I have created a SQL statement that returns all rows in my recordset, I now need to implement some additional SQL to filter the recordset using my temporary tables, which contain the filters as follows:

(1) Temp table 1 (##tblTempAssetFilt) is mandatory and will always contain at least one row.
(2) Temp table 2 (##tblTempRepairTypeFilter) is optional and may never contain any rows. If this is the case then I have no reason to filter my resultset against this table.
(3) Temp table 3 (##tblTempRepairFilter) / Temp table 4 (##tblTempRepairElementFilter) are both optional, only one of these tables will contain data at one time. Again, as an optional filter the tables may never contain rows, and thus need to be ignored.

I have the following SQL, can somebody tell me how I would go about filtering the recordset using the temporary tables. The creation of the temporary tables occurs at the beginning so will always exist even when no rows have been inserted.

SELECT *
FROM tblActualWork [ActualWork]
JOIN tblRepair [Repair] ON ActualWork.intRepairID = Repair.intRepairID
JOIN tblRepairElement [RepairElement] ON Repair.intRepairElementID = RepairElement.intRepairElementID
JOIN tblRepairType [RepairType] ON Repair.intRepairTypeID = RepairType.intRepairTypeID
JOIN tblAsset [Asset] ON ActualWork.intAssetID = Asset.intAssetID
WHERE ActualWork.intAssetID IN (Select intAssetID From ##tblTempAssetFilter) AND Repair.intRepairTypeID IN (Select intRepairTypeID From ##tblTempRepairTypeFilter)
AND Repair.intRepairID IN (Select intRepairID From ##tblTempRepairFilter)
AND Repair.intRepairElementID IN (Select intRepairElementID From ##tblTempRepairElementFilter)

Any filtering must be based on the recordset filtered by temp table 1, which is a mandatory filter. Rows will always exist in this temp table.

Please help, not having much joy with this. Many thanks.

Can I Avoid Temp Tables, Etc.

Sep 14, 2006

I need help on two questions:1. Is temp table the only way to pass recordsets from a nested storedprocedure to a calling stored procedure? Can we avoid temp tables inthis case?2. Are operations in a stored procedure are treated as a transaction?Any help will be greatly appreciated.Background: We need to use temp table to pass recordsets from a nestedstored procedure to a calling stored procedure. Our understanding isthat in this case, we have no choice but to use temp tables. So, weneed to optimize the performance as much as possible. To do this, wewanted to find out whether operations in a stored procedure are treatedas a transaction. We are using SQL 2000 SP4. I could not find anyanswers so I did the following experiment.Experiment 1:SET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS OFFGOif exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[Wiz_SP_Transaction_Test]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)drop procedure [dbo].[Wiz_SP_Transaction_Test]GOCREATE PROCEDURE [dbo].[Wiz_SP_Transaction_Test]ASUpdateArticlesSETIsUpdate = 20whereArticlesId < 80000SELECT * from ArticlesGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGO"SELECT * from Articles" takes a long time (about 40 seconds) tocompleteBefore executing the SP, the IsUpdate attribute for all articles is 30.Then I executed this SP. Before the SP is finished, I end the SPmanually. I checked the IsUpdate attribute again, and found that allArticles's (ArticlesId < 80000) Isupdate attribute is now 20. Theoperations did not rollback. I interpret this to mean that the whole SPis not treated as a transaction.Then, I did experiment 2 below. This time, I explicitly declared thetransaction.SET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS OFFGOif exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[Wiz_SP_Transaction_Test]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)drop procedure [dbo].[Wiz_SP_Transaction_Test]GOCREATE PROCEDURE [dbo].[Wiz_SP_Transaction_Test]ASBEGIN TRANSACTIONUpdateArticlesSETIsUpdate = 50whereArticlesId < 80000SELECT * from ArticlesIF @@ERROR <0 ROLLBACK TRANSACTIONCOMMIT TRANSACTIONGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGOBefore this second SP, the IsUpdate attribute is 20 (set in the firstexperiment). I run this second SP and ended it manually before itfinished. I checked the IsUpdate attributes for all Articles's(ArticlesId < 80000), but their Isupdate attribute is 50. So theoperation did not rollback either. But we have declared the transactionexplicitly. Does this mean that the SP is still not treated as atransaction?

Quastion About Temp Tables

Jul 20, 2005

I'm relatively new to SQL-Server, and I have a quick question abouttemporary tables. I am using a function from Erland Sommarskog'sexcellent article about arrays in SQL server.Erland's approach uses a user-defined function, which parses a stringof delimited values (integers) into a temporary table. The temporarytable is joined to tables in a stored procedure select statement tolimit the records returned.The question is, what happens to the temporary table generated by thefunction? Is it implicitly destroyed when the stored procedurefinishes? Does it need to be dropped explicitly (something not done inhis examples)?Also, what are the implications of scope, if multiple users areaccessing the stored procedure through a web application?Thanks in advance,Tim

Global Temp Tables

May 29, 2006

Hi group,

I want to create several global temp tables. I've created a script:

if not object_id('tempdb..##tbl_ProductTypes') is null
begin
drop table ##tbl_ProductTypes
end
select * into ##tbl_ProductTypes from dbo.tbl_ProductTypes

This script creates a global temp table. When I run it in QA the table is created. When I close QA the table is dropped. This is correct since I found the following in BoL:
[Global temporary tables are automatically dropped when the session that created
the table ends and all other tasks have stopped referencing them. The
association between a task and a table is maintained only for the life of a
single Transact-SQL statement. This means that a global temporary table is
dropped at the completion of the last Transact-SQL statement that was actively
referencing the table when the creating session ended.]

I created a job that executes the statement above. The job exists with success, however the table is not created!

Why wasn't the table created??

TIA

Regards,

SDerix

Temp Tables Or Joins

Oct 30, 2006



I had a SP to generate a recordset for a MIS report. It had 11 temp tables , basically taking data from real tables , performing some aggregation and counts and passin on the records to a temp table which gave the result as desired ..ofcourse with some group by clauses...

Now i replaced these temp tables (most of them..left with just 2), and used derieved tables instead in the final query..and joins which will execute with each query iteration..something of the sort

select col1,co2 ,

(select count(id) from sometable x group by sayaccount where x.id = temp.id) ,

(select sum(id) from (select count(id) from sometable group by sayaccount) DERIVED_Tab),

......

from #finaltemp temp

group by col1.....

(earlier the count was stored in 1 temp table, then sum one n stored in other).

the idea was to reduce the execution time...but i din achieve it...not with just a single user running the report i.e , rather it marginally increased. my thinking was that i'll be avoiding the locks on tempdb by reducing the number of temp tables....pls tell me if im goin wrong...i still have the option of using table datatype if thats feasible..

JDBC And Temp Tables

Jul 19, 2007

I'm having trouble creating and using temp tables over JDBC.


Actually, it's not so much creating as referring to a created table. What appears to be happening is that the table is created and immediately dropped, so a subsequent statement cannot refer to the newly created table.


I've already done a lot of research and experimentation and found the selectMethod=cursor connection property. Setting this property seems to have no effect.


Example queries:


1) select some.columns into #diffComp from some.table where .....
2) select * from #diffComp join foo on ......


The second query depends on the temp table #diffComp created by the first query. When I trace this in Eclipse, the value returned by getUpdateCount() on the first query is the correct number of rows. The second query is executed immediately aferwards, and ALWAYS throws :

com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name '#diffComp'.


I'm also able to look inside the connection objet in Eclipse, and can confirm that the activeConnectionProperties member DOES contain selectMethod=cursor.

Any suggestions?
