it seems like i am able to create it. But when i try to access that
temporary table, i get an error "Invalid object".
this is happening only when i try to create local temporary table.
Global temporary table works fine inside the dynamic SQL.
Any Help appreciated.
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

i have a requirement that a temporary table contains dynamic columns depending on where condition.
my actual table is like
Key
Value
X1
x
X3
x
X5
x
Y1
y
Y2
y
when user select x, the input variable passed to stored proc and the result is shown like
column names
X1 X3 X5 as column headers.
the select query is from temporary table.
these out put is based on the user selection. so the temporary table created with columns dynamically.
please help me out.
please let me know if you didn't understand.
thanks

Hi,
I'd like to create a temporary table (# or ## table) and have it available in DataFlow to work with it. I see I can create it using "Execute SQL Task" component in ControlFlow; but it's not available in DataFlow. It seems it should be created by a DataFlow component to be seen in the same DataFlow.
Any Idea on this?
Dear All,
This is my first post to this forum.
I would like to know if there is any way to restrict users from creating temp tables.
Problem: I am facing problems with lots of temporary objects getting created in my database. The users have read-only access to the database for adhoc-querying purpose through QA. Yet they are able to create temporary tables in tempdb database taking lot of resources on tempdb disk causing abnormally high growth of tempdb.
Thanks in advance.

I m trying to create a global temporary table whose data will be deleted after the end of the session..
the DDL in oracle is
CREATE GLOBAL TEMPORARY TABLE STUDENT
(
name CHAR(20),

I want to know the corresponding DDL in SQL Server..
when i try the following
CREATE TABLE ##STUDENT
(

the table gets deleted at the end of the session..help needed
When I run the query below on my DB, it gives the following error:
Server: Msg 8114, Level 16, State 5, Procedure partstlist ...Error converting data type varchar to float.
Only after I replace the " + @d + " section with a float numnber such as 39020.5 does it work fineIt's reported that my temporary table named #tbl doesn't exist within the scope of the environment that the EXEC(UTE) command operates.Someone said that I couldn't combine dynamic SQL and temporary tables or table variables...and that I would have to use a global temp table "##tbl" or a permanent table.
So here I have appearantly a "DYNAMiC SQL & TEMPORARY TABLE" problem. That's sure.
But I don't have much knowledge and experience with SQL tables and have difficulty forming a global temp table "##tbl" or a permanent table.and I have to employ the datetime variable dynamically @d inside the Dynamic SQL string.
So what kind of a code should I use here to properly combine Dynamic SQL string with my dynamic datetime variable? I'd be grateful if you could post your code suggestions so that I can try them on my DB ..

This code may not be syntatically correct, it's a re-edited version of my code which works fine in my DB.

Something likethis:CREATE PROCEDURE procname@sortby varchar(30)ASBEGINSELECT some, columnsFROM some_tableORDER BY @sortbyEND(of course, i know this won't work, but it gives the idea of what i mean)Is there a possibility to write a procedure which behaves like that?

When I use comands insert and update with VB5 and ODBC, one temporary stored procedure is created in database tempdb to each command executed.
These stored procedures are deleted only when the connection is closed.
My program use comands insert and update inside a loop, and a lot of temporary stored procedure are generated and full the database tempdb. When it occur, others systems are afecteds.
My questions:
Why it occur ?
Wich have created this stored procedure ?
How to avoid it occur ?
The versions are:
SQL Server 6.5
Visual Basic 5.0
SQL Server ODBC Driver 2.65.0240
*Groan* Sorry. One more.
ERD above is what my database looks like (ignore it's in Access, database is in SQL 2005)
I have this code:
SELECT orderID, orderAmount = SUM(customerID)/customerID FROM orders
GROUP BY orderID
-- When Sum of the customer ID (and then) divided by the customer ID > 1
HAVING orderAmount > 1
which doesn't work because I never did find out how you make a column in the results to output your maths in.
orderAmount doesn't exist as a column in the database, but for this query it should show only those customers who have ordered more than once with the company.
Thanks again for any replies.

I have a specific requirement.
I have to generate a report on the fly.
The display fields, parameters and sort conditions would be user specified at run time in a ASP.NET web form. There will be a superset of the display, filter and sort fields out of which the user cans select one or more.
From the web form, i am taking these three parts as three strings and sending them as parameters to a Stored Procedure. The Stored Procedure will read each string, and identify what are the individual fields and generates the result accordingly.
So here my requirement is that Reporting Services must read the Stored Procedure, create a dataset and even create the User Interface all at run-time as we do not know what fields are displayed at design time. The Headers for each field come from the Stored Procedure. I have to show the report based on what are the fields in the Stored procedure at that instance of time.
I hope i have explained very clearly.
I would be grateful for your contributions.
Thanks
Can you create a temporary table using an ad-hoc query?
What I am trying to do is a type of filter search (the user has this and this or this) were i will not know how may items the user is going to select until they submit....that is why i can't use a stored procedure(i think)....any help on how to do this?
Thanks,

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...
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?
How can I view logs of local (to a session) temporary that are created/dropped?

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?
If a stored procedure invokes another stored procedure that creates atemporary table why can't the calling procedure see the temporary table?CREATE PROCEDURE dbo.GetTempASCREATE TABLE #Test([id] int not null identity,[name] as char(4))INSERT INTO #Test ([name]) VALUES ('Test')CREATE PROCEDURE dbo.TestASEXEC dbo.GetTempSELECT * FROM #Test -- Invalid object name '#Test'.Thanks,TP

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.

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

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?
Thank you!

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.

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.
