Global Temporary Table
Dec 23, 2006
Hi,
what im trying to do is to combine multiple SELECT staetment so that it could produce 1 dataset instead of 2(multiple). (fields and column are same, just different tblname). Okay, so im thinking of insert those into temp table.
1. select statement 1 > insert into #MyTemp
2. select statement 2 > i want to insert into #MyTemp too...
Problem is sql disallowed this. That's why im thinking of global temporary table, but dunno how to write tht :P.
Pliz help. Thanks in advance

Hello all,I'm using SS2K on W2K.Brieffing: Many months ago, I created a stored procedure only used by thosewith admin rights in SS. Now, someone else (without admin rights) has to runit. I gave him rigth to execute the SP but, at the second and moreexecution, he got a error message concerning a temp table already existing(see further).The SP:------------------------------------------------------CREATE PROCEDURE MySP@Type INTDECLARE @strSQL AS VARCHAR(4000)IF EXISTS (SELECT table_name FROM tempdb.information_Schema.tables WHEREtable_name = '##MyTmpTable')DROP TABLE ##MyTmpTableSELECT @strSQL = 'SELECT MyField1, MyField2, MyField3 INTO ##MyTmpTable FROMMyTable'EXECUTE(@strSQL)IF @Type = 1SELECT MyField1FROM ##MyTmpTableELSE IF @Type = 2SELECT MyField2FROM ##MyTmpTableELSESELECT MyField3FROM ##MyTmpTableGO------------------------------------------------------The error I got on the second time the user run the sp is: "Table##MyTmpTable already exists." The front-end where this SP is run is A97.That's where I got this message. This SP looks like a simple SELECT queryfrom A97 users perspective.Please, do no argue about the way of doing the work done! It is simplifiedat most in order to make it short and easy to read. I have to use thecommand "EXECUTE(String)" and, because of this, I connot use a localtemporary table instead of a global one.I suspect non-admin user cannot drop global temporary table, but the errormessage makes me believe that this code line is not even run, as if thecondition "IF EXISTS(...)" return false even if the table actualy exists.Anybody can help about this? What should I do to solve this problem?Yannick

We are trying to use a ## table (global temporary table) in Access or Excel thru a ODBC connection to tempdb. We are able to see the system tables, but not any ## tables. We are able to perform selects on the same ## table with the same userid and password in Query Analyzer. If we use sa or make the userid dbo we are able to see the ## tables, but I don't want to give these type of permissions.
Any help would be appreciated. Thanks in advance.

Hi,
I have a report that calls a stored procedure that creates an extract of data for use by various subreports. Now I have this problem:
If I save the extract data in a global temporary table, then it is automatically deleted before the subreports can use it, this means I have to create a normal table with a unique name that need to be deleted - but where do you do this in the report - there is no point where you can say it is now safe to delete a table?
I do not want to resort to external mechanisms, languages, jobs etc. to do this. I want to delete the table once the report is really finished in the report.
My main report uses a list that contains all the subreports as I need to group all sorts of information by vendor. The main report calls the stored procedure. Please do not tell me that I have to duplicate the main extract for every subreport. That will really eat resources.
Thanks in advance.

I have a table that includes the html-output of different parts of my pages. This table grows very big very fast, and rows older than 24 hours are useless.
My question is if it is possible to have temporary rows, whose are automatically deleted after these 24 hours? And then how to accomplish that?

How do I use table names stored in variables in stored procedures?
Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000
I receive the error 'must declare table variable '@tablename''
I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.
Code Snippet
if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename
It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.
Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.
Heres the actual SQL query that produces the temporary table error.
Code Snippet
Select * into #temptableabcd from TableA
Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB
TRUNCATE TABLE TableA
Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB
The above coding produces
Msg 208, Level 16, State 0, Line 1
Invalid object name '#temptableabcd'.
Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?
Thanks for the help.

Using SQL against a DB2 table the 'with' key word is used todynamically create a temporary table with an SQL statement that isretained for the duration of that SQL statement.What is the equivalent to the SQL 'with' using TSQL? If there is notone, what is the TSQL solution to creating a temporary table that isassociated with an SQL statement? Examples would be appreciated.Thank you!!

I need to decide what is better to use: global temp table ( I can't use local one) or permanent table in SQL 2000 stored procedures. I extract data from linked server table and update several tables on our server.
Those procedures scheduled to run every 3 hours.
Another question: for some reasons when I used global temp table, I wasn't able to schedule multi steps with every step executing one of the stored procedures.I think global temp tables should be visible to other stored procedures, right?
Your suggestions?

I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures.
Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example:
StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1...
Or using a table-valued function to return a temp table as the result.
I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.

Hi:
A regular permanent table is not an option:
Need to exec a procA which at the end also exec procB.
procA will insert to table A and also generate a intermidate result set to a ##A global table, it works fine at this point. However, when it exec the procB at the end of exec procA, the ##A global table is empty when entering procB.
The key is I want to pass a records set to the procB without using a tableTempB. Does a ## global table should be still alive until procB execution is done?
I also tried use table variable, but it does not look like to accept @tableA
as part of the procB's parameters.
Also tried function, but it could not support a #tempTable within it which will do a dynamic query insertion.
thanks
David

Hi
I am using SQL 2000 I have the following code. When saving it, I am getting an error:
There is already an object named '##tbl' in the database
This is although #tbl is dropped.
Is threrea way to avoid this error? the only work around I found was to create a string with the SQL command and call EXEC, but I don't like this solution as it prevents early compilation of the procedure.
declare @x int
set @x=1
IF @x=0
begin
create table #tbl (
abc int
)
drop table #tbl
end
IF @x=1
begin
create table #tbl (
abc int
)
drop table #tbl
end
Than you.

I have the following fields in table A:
GL_ID|GL_Name_VC| Amount |Period_TI|Year_SI|
===================================================
1000| Sales | -20,000.00 | 01 | 2005
===================================================
1000| Sales | -10,000.00 | 02 | 2005
===================================================
1001| Cost | 5,000.00 | 01 | 2005
===================================================
1001| Cost | 5,000.00 | 02 | 2005
the fields above have the following datatype:
Fields | Datatype
===================================
GL_ID | Integer
GL_Name_VC | Variable Character
Amount | Integer
Period_TI | TinyInteger
Year_SI | SmallInteger
The above database is running on Microsoft SQL Server 2000 and i would like to query
for a report that looks something as below:
Description | Period 01 | Period 02 | Year to Date
=========================================================
Sales | 20,000.00 | 10,000.00 | 30,000.00
Total Sales | 20,000.00 | 10,000.00 | 30,000.00
Cost | 5,000.00 | 5,000.00 | 10,000.00
Total Cost | 5,000.00 | 5,000.00 | 10,000.00
=========================================================
Profit | 15,000.00 | 5,000.00 | 20,000.00
The above report would list 4 columns, with the last column being a calculated field as a sum of
Period01 + Period02 Amount, sorted by GL_ID and group under a summation row called
Total Sales & Total Cost.There would be a net amount appearing as Profit (Total Sales-Total Cost).
Guys, hope someone out there can help me with the sql command for the above report?

Hi,
i have:
[first table]
user_id
user_name
user_password
[second table]
set
item
order
Since the second table is somehow only temporary table (having at the front ajax script), i need the third table to store user's ID and all the info from second table.
What would be the easiest way to do it, since the first table contains only one row per user and the second one 40 rows per user.
thank you for your thought!

Hi
I call some SQL server procedures via OLEDB under Visual C++.
[ Commands like " EXEC myProc 'param1', 'param2' " ]
My connection string is Provider=SQLOLEDB;Data Source=.SQLEXPRESS;Integrated Security=SSPI;Initial File Name=C:devsrcindb.mdf
I encounter a pb when there is a 'SELECT (...) INTO #table' into my db procedure.
Something like:
ALTER PROCEDURE myProc
AS
SELECT 1 as 'return1', 2 as 'return2' into #table
SELECT * FROM #table
RETURN
works of course very well when I call it from Visual or Server Management Studio Express
but doesn't return any recordset when I call it from OLEDB.
2nd thing:
SELECT 1 as 'return1', 2 as 'return2' into table
SELECT * from table
-> table is created [I can see it in the db], but no selection is returned to my OLEDB caller.
Is it a security pb ?

I have a pivot table implementation, part of which is posted below. Itreturns no errors in query analyzer, but when profiler is run, it showsthat "Error 208" is happening. I looked that up in BOL and it meansthat an object doesn't exist.

Hello once again,
My last question concerns (temporary) tables. In a web form (VWD Express, Asp,Net 2.0, VB, .mdf db, Ajax) I have two gridviews. One gets its data from textboxes and dropdownlists as the user clicks an ok button. This data is then sent to a "junk" table in the db. The other gridview retrieves this data "automatically" and displays the data, filtered and grouped by some SQL statements. When the user finally clicks an Insert record button, the data from this second gridview gets inserted in another table in the db and the data from the first "junk" table is disposed.
I guess it shouldn't be necessary to insert, retrieve, and delete the data in and from the "junk" table. Even though it does work like a charm, I guess it would be better if I could do it wit hsome kind of "temporary table", array or the like so that the db wouldn't need to be updated to this extent. Still, I really like the simplicity of using gridviews and the rest of the page's code is complex enough, so I don't really want to substitute this behaviour for tons of hand-written, hard-to-follow, and hard-to-integrate code.
What are my options? Any help would be greatly appreciated.
