Drop Temporary Tables Whilst Connected ?

Jul 20, 2005

Just a quicky about temporarary tables. If using QA, when you create a
temporary table, it gets dropped if you close the query. Otherwise you
need to state 'DROP TABLE myTable' so that you can re-run the query
without the table being there.

Sometimes, you can have quite lengthy SQL statements (in a series)
with various drop table sections throughout the query. Ideally you
would put these all at the end, but sometimes you will need to drop
some part way through (for ease of reading and max temp tables etc...)

However, what I was wondering is :

Is there any way to quickly drop the temporary tables for the current
connection without specifying all of the tables individually ? When
testing/checking, you have to work your way through and run each drop
table section individually. This can be time consuming, so being
naturally lazy, is there a quick way of doing this ? When working
through the SQL, it's possible to do this quite a lot.

Example

SQL Statement with several parts, each uses a series of temporary
tables to create a result set. At the end of a section, these work
tables are no longer needed, so drop table commands are used. The
final result set brings back the combined results from each section
and then drops those at the end.

TIA

Dynamic Tables Names And Temporary Tables Options

Oct 5, 2007

Firstly I consider myself quite an experienced SQL Server user, andamnow using SQL Server 2005 Express for the main backend of mysoftware.My problem is thus: The boss needs to run reports; I have designedthese reports as SQL procedures, to be executed through an ASPapplication. Basic, and even medium sized (10,000+ records) reportingrun at an acceptable speed, but for anything larger, IIS timeouts andquery timeouts often cause problems.I subsequently came up with the idea that I could reduce processingtimes by up to two-thirds by writing information from eachcalculationstage to a number of tables as the reporting procedure runs..ie. stage 1, write to table xxx1,stage 2 reads table xxx1 and writes to table xxx2,stage 3 reads table xxx2 and writes to table xxx3,etc, etc, etcprocedure read final table, and outputs information.This works wonderfully, EXCEPT that two people can't run the samereport at the same time, because as one procedure creates and writesto table xxx2, the other procedure tries to drop the table, or read atable that has already been dropped....Does anyone have any suggestions about how to get around thisproblem?I have thought about generating the table names dynamically using'sp_execute', but the statement I need to run is far too long(apparently there is a maximum length you can pass to it), and evenbreaking it down into sub-procedures is soooooooooooooooo timeconsuming and inefficient having to format statements as strings(replacing quotes and so on)How can I use multiple tables, or indeed process HUGE procedures,withdynamic table names, or temporary tables?All answers/suggestions/questions gratefully received.Thanks

Hello specialists.

Maybe this is the wrong formum but I've got a question for which you probably have the answer, i hope.


Situation
------------
John is member of Group_A and Group_B
Bill is member of Group_B and Group_C
Allison is member of Group_A and Group_E

How can I create a query to input Allisons username into table 1 and groupmembership into table 2. Also updating the relationship within junction-table3 must be done automaticaly. I want to avoid duplicate records.
The final situation I want is given in red text.

The relationships between the tables are as follows
-------------------------------------------------------------
Table1 (PK)ID-Userinfo [ONE] <------------> [MANY] Table3 ID-Userinfo

Create Default Tables, Procedures, Etc. On Newly Connected Remote SQL Server

Jan 5, 2007

I have a website I'm ready to test on the server it will call home. I just got connected to the remote SQL server that it will be using. As I've been creating the site, I've been using the default SQL Express set-up in Visual Studio. Is there a way to have Visual Studio create all those default tables, procedures, etc. OR is there a way to copy all of that stuff from the SQL Express running on my machine to the remote SQL Server 2005?

Temporary Tables

Jan 15, 2007

Afternoon.

I'm having trouble with a query and ASP. The query itself is easy. I need a temporary table to be filled with the contents of a select and then i need to select out of the temporary table and return the results to the ASP.

So:


Code:

DECLARE @RESULTS TABLE (
ItemID int,
ItemDescription char(50),
ItemType int,
ItemRequestedBy char(50),
ItemStatus int,
ItemQuantity int,
ItemCostPer money,
ItemOrderNumber int,
DateAdded smalldatetime,
DateLastEdited smallDateTime
)

INSERT into @results (ItemID, ItemDescription, ItemType, ItemRequestedBy, ItemStatus, ItemQuantity, ItemCostPer, ItemOrderNumber, DateAdded, DateLastEdited)
SELECT * from cr_EquipmentData

SELECT * from @results



When I run this in Query Analyser, I get exactly the results I need... But when I try and run the ASP script, I get an error about the recordset not being open. (It's not the ASP checking 'cos when I run a simple select statement it works)

I appreciate there is no use for the query as it stands, but eventually I want to be able to perform not destructive statements on the @results table before returning the data to ASP. This is more 'testing' than anything at the mo'

Has anyone got any ideas?

Thanks...

Temporary Tables

Apr 14, 2004

I am writing a stored procedure that outputs it's information to a temporary table while it assembles the information. Afterwards, it returns the contents of the temporary table as the results of the stored procedure.

I found that if you create the table, inside the SP, as an ordinary table, the information builds to that table considerably faster than if you use a true temporary table.

I found that if I create a user function that returns a table as it's return value, it is also as slow as if I used a true temporary table.

The database can amass over 2 million records in one table in just a few days. If I have the procedure query against this table, and output to an ordinary table it creates, and summarize the information it is adding to the table, then it takes an average of around 4 minutes to return the results from the query. If I change the output table to a temporary table (#temp), it between 12 and 15 minutes. Nothing else in the procedure changed. Just the kind of table. If I take the logic and move it to a function which returns those results in a RETURN table, it also takes over 14 minutes.

Why would it take so much longer outputing to a temporary table rather than a normal table? Is it because temporary tables are stored in a different database (tempdb)? Why would returning query results from a function be just as slow?

Temporary Tables

Nov 2, 2007

Hello,

Our java application is running on oracle and now we would like to port it to sql server 2000. In oracle we have a global temporary tables that has an option on commit to delete rows.
Now I am looking for the same option in sql server but as far as I can see sql server's local temporary tables are visible per connection. Since the connection are shared in the pool it seems I can not rely on local temporary tables since the connection does not get closed at the end of the user's session. I need something that is visible per transaction not per connection.

Is it a better approach just to create a regular table and basically have a trigger to delete all data on commit?

Not Able To Use Temporary Tables

May 8, 2007

Hello,



I would like to know from other members whether they are successful in using temporary tables within a stored procedure and use that stored procedure in a report.



My scenario is like this:



I have a stored procedure A which fetches the data from different tables based on the orderno passed as input parameter.



I have built another stored procedure B with a temporary table created and inserting the rows in to this temporary table based on vendor related specifc orders by calling the above procedure A.



I have used this stored procedure in the dataset created and getting this error:



Could not generate a list of fields for the query. Check the query syntax, or click the Refresh Fields on the query toolbar.



Does anybody encountered this and have a resolution.



Thanks in advance.

Temporary Tables

Dec 12, 2007

Hi All

declare @temp table

([EVENT_TYPE_ID] [int],

[Desc] [nchar](50) NOT NULL,

[Lead_Time] [smallint] NULL)

INSERT @temp

SELECT *

FROM TBL_EVENT_DEFINiTION

The table definition for @temp is the same as TBL_EVENT_DEFINiTION. The problem is I need to add a field to the @temp table and define the values using an update statement. If I include the additional field in the @temp table declaration then I get an error saying something to the effect of the number of fields is different. Is there a way of altering the temporary table to add this field?


Many thanks in advance

Temporary Tables

May 15, 2006

Hello!

I'm creating a temporary table in a procedure to help me with some calculations. I would like the name of the temporary table to be 'dynamic', I mean, to have the hour it was created, something like this: create table #myTempTable15May11:10:00, so if someone access the procedure while it's running, he won't have problems in creating his 'own' temporary table (create table #myTempTable15May11:10:02). Is there anyway I can do this?

Temporary Tables

Aug 9, 2007

Hi,

I have some questions regarding Temporary tables.

I need to use a temporary table within a stored procedure (which is a transaction), should I use local temporary table or global temporary table?

If I use a temporary table in my transaction, do I destroy the temporary table at the end of the transaction, or just leave it, and let the sytem clean it up? If I destroy the temporary table at the of the transaction, what happens if another user session is accessing the temporary at the very moment?

Thanks.

Paging With Temporary Tables

Jun 8, 2005

I am searching for information on paging large datasets, and have found
some that involve creating temporary tables in the database. 
Before I head off and implement something, I have a number of issues
I'd like to bounce around here. 

1. An example I found on MSDN involves creating a temporary table,
copying relevant columns to the row in the temp table.  Why do
this, rather add the source tables primary keys into the temp table,
and do a join? Example;  browsing Products Catalog which is
categorised into hierarchies.  The MSDN version would have a temp
table created with a incrementing field which is used for the paging,
and then a number of fields are also copied from the products table to
the temp table - my question is why not simply copy the product primary
key into the temp table, and then join?

2. In real life, do people allow each user to create their own
temporary tables? If I have 1000 concurrent users, all wishing to
perform a page-based browse, I would be creating 1000 new temporary
tables.  Do people consider default temp tables, that is, creating
a default temporary table for browsing each category in the products
table, for example?

3. Do you have any advice/tips for this type of problem?

Thanks!

JR.

Temporary Tables -- Please Stay!

May 1, 2000

In Access 97/2000, a local table can be created in the program database, while the data is stored in a linked database. This is useful for me to do a sort-of iterative drill-down on linked tables, e.g. filter table1 into table2, then further filter table2 into table3 and so on.....

If I do this I leave a trail that I can navigate in reverse (back up a step).
This is very important in my app.

So now my problem is....I'm trying to duplicate this in an ADP file using only ADO 2.5. I have no local tables, only server tables. If I create a temporary table, it only exists until the procedure ends.

Is there any way to create temporary tables that are specific to a user session and do not automatically delete themselves, or is there a better way to do this in SQL7?

Select Into Temporary Tables

Jan 28, 2004

on sql-server-performance.com i read :
Do not create temporary tables from within a stored procedure that is invoked by the INSERT INTO EXECUTE statement. If you do, locks on the syscolumns, sysobjects, and sysindexes tables in the TEMPDB database will be created, blocking others from using the TEMPDB database, which can significantly affect performance. [6.5, 7.0, 2000] Added 9-1-2000

I have a question does this negative effect also include simple SQL commands apart from stored procedures.
For example if from vb i execute a "Select into" temporary table. Will this have the same negative impact as with executing this from a stored procedure ?

Thank you very much

Persistance Of Temporary Tables

Jan 30, 2008



hi,

I'm going through some stored procedures that have been written previously.
In every sp, they are checking for existance of temporary table in sysobjects.

So, i made a simple script and checked if #TempTable has a entry in sysobjects.
But i did not find it.

On internet many ppl are talking about checking if temp table already exists.
So my question is...

1. What are circumstances under which temporary table doesn't get deleted
automatically.
2. Does temporary table have a entry in sysobjects?



Thanks
Sandeep
