Temp Table Exists
Sep 14, 2000What is the best way to programmatically determine if a temp table exists? In 6.5, I would use
IF EXISTS(SELECT * from tempdb..sysobjects where id = object_id('tempdb..#MyTable') and type = 'U')
But now that it is strongly discouraged to code against system tables, how could I re-write this statement?
The proper way to check the existence of a table would be:
IF OBJECTPROPERTY(object_id('tablename'), 'IsTable') = 1
However, to get this to run for a temp table, I think you'd have to change the database context to tempdb and then back to your database. That doesn't seem efficient.
I could use
IF object_id('tempdb..#MyTable') IS NOT NULL
But that's not guarenteeing that it's a table, right?
Any ideas?

MDF File Still Exists After DROP TABLE
Nov 5, 2005Hello,Using Enterprise Manager, I deleted from my database the only tablethat contained records (Right-Click on Table, Choose "Delete Table").My expectation was that the LARGE .mdf file would be reduced to minimalsize (at least as small as the Northwind MDF). However, it's still 4+Gig in size!! (Northwind is 2.62 MB). This is a problem, bc I deletedthe table in order to recapture hard drive space.NOTE: I already tried using Shrink Database in EM. This significantlyreduced the size of the .mdf file from its original (i.e. pre-delete)size of 38 Gig to present size of 4 Gig.What can I do to further reduce the size of the MDF file?Thank you.

Jul 23, 2005HelloI am using a temp table called ##temp in an SProc but often get themessage that the table already exists. Could this be because the SProcis being run by more than 2 webpages at the same time?Or is it because the sProc has an error and is not getting to the droptable line?I have tried adding a line to test if the object exists and to drop thetable before I create it. If I drop it will it affect another instanceof the sProc that is using the same table name?If so is there a way around this?Many thanksNigel

Drop Existing Temp Table
Nov 7, 2007hello!! i am using a couple of temp tables for a select statement.
i need to drop the tables only if they exist before using them, because if i don't drop, then i will get this error:
There is already an object named '#Tmp01' in the database.
and if i try to drop the tables for the first time i run the query, then i will get an error saying that i cannot drop a table that doesn't exist.
i have tried using this sentence:
IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp01') DROP TABLE #Tmp01
IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp02') DROP TABLE #Tmp02
IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp03') DROP TABLE #Tmp03
but it only seems to work with normal tables, since temp tables are not found in sysobjects.
any suggestions??
thnx
DROP Temp Table Or Any Scripts
May 17, 2007Hi,
What control can I use to put any scripts like that?
ExecuteSQLTask lets me do just sql query.
I need to have something like this.
USE [DB1]
GO
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Lookup]') AND type in (N'U'))
DROP TABLE [dbo].[Lookup]
or Create
CREATE TABLE [Lookup] (
[MD_ID_Old] INTEGER,
[MD_ID_New] uniqueidentifier
)
I need to find the way to use scripts in SSIS.
Thanks.
Transact SQL :: If Not Exists Some ID In One Table Then Insert ID And Description In Another Table
Jul 14, 2015I need to find out if a Transaction ID exists in Table A that does not exist in Table B. If that is the case, then I need to insert into Table B all of the Transaction IDs and Descriptions that are not already in. Seems to me this would involve If Not Exists and then an insert into Table B. This would work easily if there were only one row. What is the best way to handle it if there are a bunch of rows? Should there be some type of looping?

Example: 'permTable' has col1 and col2. The data in these two rows plus the name of the table from which it came ('permTable' in this example) are to be added to #temp.
Data in permTable
col1 col2

Data in #temp after permTable's filtered contents have been added
TableName, col1 col2
permTable, 11, 12
permTable, 21, 22

Transact SQL :: Temp Table - Display Duplicate IDs In Multiple Rows

drop table #temp
create table #temp (id int,DLR_ID int,KPI_ID int,Brnd_ID int)

insert into #temp values (2,2343,34,2)

I use the rank function on that table and get the following results
select rank() over (order by DLR_ID,KPI_ID,BRND_ID ) Rown,* from #temp
I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)

Transact SQL :: How To Store Result Of Exec Command Into Temp Table
Apr 7, 2013I wanted to insert the result-set of a Exec(@sqlcommand) into a temp table. I can do that by using:

For this to accomplish we need to define the table structure in advance.

So my question is how to insert/capture the result-set of Exec(@sqlcommand) into a temp table when we don't know the table structure.
Transact SQL :: Create Temp Table That Persists While A Front End App Is Open
Sep 30, 2015I have an Access app. that I am migrating the DB portion (queries, tables) to SQL server. I need to create a temp table that lasts as long as the user has the Access FE app. open. Idea is that the temp table stores the user's parameters (used for filtering data entry forms and report). The parameters allow the app. to only show the user his data (cannot view other users data). The SP shown below works OK, it creates a ##Temp table and updates it with the parameters sent by Access FE app. The issue I am having is that as soon as the SP finishes the ##Temp table is removed. I thought of using a regular table, but, I am currently testing this migration in my local SQL server instance, as soon as I move the database to production environment, then users will not be able to create tables as permissions are only read/write.

Transact SQL :: Present Data In Presentation Layer After Removing Temp Table?
May 21, 2015Inside of stored procedure you have the code

phone varchar(10),
cellphone varchar(10),
none varchar(10)

insert into #datatable
exec ('select *
from datatable
where id = 1')
select * from #datatable
I still want to retrieve the data and present it in the software's presentation layer but I still want to remove the temp table in order to reduce performance issue etc.
If I paste the code DROP
TABLE #datatable after
insert into #datatable
exec ('select *
from datatable
where id = 1')
Does it gonna work to present the data in the presentation layer after removing the temp table?
The goal is to retrieve the data from a stored procedure and present it in the software's presentation layer and I still need to remove the temptable after using it because I will use the SP many time in production phase.

Transact SQL :: Select 1000 Rows At A Time From / Into A Large Temp Table?
May 12, 2015I am using SQL SERVER 2008R2, not Denali, so I cannot use OFFSET FETCH Clause.
In my stored procedure, I am doing a SELECT INTO #tblTemp FROM... Working fine. This resultset is going to be used in an SSIS package which will generate a pipe-delimited .txt file... Working fine.
For recoverability sake, I am trying to throttle back on the commit chunks to 1000 rows per commit until there are no more rows. I am trying to avoid large rollbacks.
Q: Am I supposed to handle the transactions (begin/commit/rollback/end trans) when the records are being inserted into the temp table? Or when they are being selected form the temp table?
Q: Or can I handle this in my SSIS package for a flat file destination? I don't see option for a flat file destination like I do for an OLE DB Destination (like Rows per batch, Maximum insert commit size).
