Drop ##temp
Nov 8, 2006
due to unavoidable reasons i had to use a ## temp table in a SP,
ie i had to dynamically create a table whose (number of)columns i come to know at runtime..
if i do thi ::set @sql = 'create #table....select some columns _ append varchar(10)'
then insert into #temp....temp is not valid here..so i used ##temp
now i need to explicitly drop it...also in catch block , i need to make a provision for droping it incase of an error in runnin proc...some kind os IF EXISTS drop ##temp.... as i dont know if it'll be created by that time or not..how do i do it..there is ofcource no entry in sysobjects....where is the entry for temp tables...tempdb dosent have system tables..!!

Using SQL Server 2005. I have a stored prod that uses a temp table. I need to test at the start of the prod to see if the temp table is there. Using the following code at the start of my prod, but does not run.
IF exists(select * from ##TO_STATUS_TBL)
DROP TABLE ##TO_STATUS_TBL
What is the best way to check and/or drop the temp table.
Thank you, David

hello!! 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

Hi,
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.

Hello,
I have a query that's in development that uses several temp tables. In order to test the query repeatedly while it's being written I have the following code at the beginning to discard the temp tables. This allows the query can recreate the temp tables when called in the code.
if object_id('tempdb..#temp1') is not null drop table #temp1
if object_id('tempdb..#temp2') is not null drop table #temp2
if object_id('tempdb..#temp3') is not null drop table #temp3
if object_id('tempdb..#temp4') is not null drop table #temp4
if object_id('tempdb..#temp5') is not null drop table #temp5
Even though this works, it takes multiple lines of code. One of my queries has to drop 12 temp tables, thus 12 lines of code. I have been experimenting with looping the above as follows:
declare @n as nvarchar(3), @table as nvarchar(10)
set @n = 1
while @n <= 5 begin
set @table = '#temp'+@n
if object_id('tempdb..#temp'+@n) is not null drop table @table
set @n = @n + 1
end
Unfortunately, the above does not work. It gives this error message:
Server: Msg 170, Level 15, State 1, Line 5
Line 5: Incorrect syntax near '@table'.
I have also tried:
declare @n as nvarchar(3), @dropstmt as nvarchar(25)
set @n = 1
while @n <= 5 begin
set @dropstmt = 'drop table #temp'+@n
if object_id('tempdb..#temp'+@n) is not null @dropstmt
set @n = @n + 1
end
This does not work either. It gives this error message:
Server: Msg 170, Level 15, State 1, Line 5
Line 5: Incorrect syntax near '@dropstmt'.
Does anyone know how to get this to work?
Thanks.

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"?

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

1. get the Resourcekey from #Base_Resource and insert into #Resource table
2. Get the SCOPE_IDENTITY(),value and insert into to

Hi folks.
Here i have small problem in transactions.I don't know how it is happaning.
Up to my knowldge if you start a transaction in side the transaction if you have DML statements
Those statements only will be effected by rollback or commit but in MS SQL SERVER 7.0 and 6.5
It is rolling back all the commands including DDL witch it shouldn't please let me know on that
If any one can help this please tell me ...........Please............
For Example
begin transaction t1
create table t1
drop table t2
then execute bellow statements
select * from t1
this query gives you table with out data
select * from t2

but if you rollback
T1 willn't be there in the database
droped table t2 will come back please explain how it can happand.....................

I think this is a very simple question, however, I don't know the
answer. What is the difference between a regular Temp table
and a Global Temp table? I need to create a temp table within
an sp that all users will use. I want the table recreated each
time someone accesses the sp, though, because some of the
same info may need to be inserted and I don't want any PK errors.
thanks!!

Hi,
I have an sql script, which updates some values by using BIT operations..
ex:
UPDATE table1
SET myValue = myValue & ~mask | (availability - mask)...
Problem is, this returns a value, when written to binary, it's one bit too long!
ex:
0
1
1
1
1
1
(= 62)
which should be:
0
1
1
1
1
0
(=31)
How can I "drop" this last BIT?
(Keep in mind that I store these values as LONGINT's)...
Been fighting with this one all day..

Hi folks,
Wonder if I'm onto something....everything I've read says that to drop foreign key constraints, you have to drop/recreate the table.
I've been able to dynamically create the ALTER TABLE statements for all FK constraints in a database. The way I did was a little convoluted (Access 97 linked tables and pass-through queries, cut/paste from the debug window to SQL7 QA), but it does work. More importantly, it saves the hassle of dropping/recreating tables....Someone with more expertise than I in using nested cursors could probably convert it to pure T-SQL pretty easily.
Just curious...opinions? Be glad to post the code here if that's appropriate.

I am managing 120 gb SQL7 database. The 120 GB is in a RAID5 (Hardware RAID). At begining, I think I should create a user defined filegroup besides Primary filegroup, as BOL suggested.
After I read some discussions here, It appears I cannot gain any performance by adding second filegroups. Now I want to drop the filegroup I created. The Question is How?. If I do alter database, move all files from userdefined filegroup, does this mean my userdefined filegroup has gone?
Someone can help me on this!
Thanks a lot.

I am trying to drop the database through the application designed using vb.net. Through login form i am logging into the database from the application. There is an option for the user to take the backup and restore the database using the application. I am able to take the backup of the database. To restore the database, i am dropping the existing database. I am unable to drop the database as an error message is being displayed saying that "Cannot drop the database, as it is currently in use". I tried to drop the database even by changing the database names in the connection string.
But i am unable to drop the database. If any one finds the solution for this please help me. Its very urgent.

does anyone know how to drop the last part of an ip address? I've been searching various sites for string functions and havn't come up with anything that works. What I want is something that will "find the third occurance of a "." and then return everything to the left of it"
I've tried various types of InStr and even found a SUBSTRING_INDEX function, but apparently it's only for mysql.

Hello, I have hit the wall here...can't make sense of this one.
I have a script that creates a PRIMARY KEY constraint called PK_tblDRG
CODE:
ALTER TABLE [dbo].[tblDRG]
ALTER COLUMN [record_id] Uniqueidentifier NOT NULL
Go
ALTER TABLE [dbo].[tblDRG]
WITH NOCHECK ADD PK_tblDRG PRIMARY KEY CLUSTERED
(
[record_id]
) WITH FILLFACTOR = 90 ON [PRIMARY]
All is fine with that. I run this to verify:
EXEC sp_pkeys @table_name = 'tblDRG'
,@table_owner = 'dbo' ,@table_qualifier = 'Relational_05Q3'
which returns this:
TABLE_QUALIFIERTABLE_OWNERTABLE_NAMECOLUMN_NAMEKEY_SEQPK_NAME
Relational_05Q3dbotblDRGrecord_id1PK_tblDRG
Now I want to drop the constriant if it exists:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PK__tblDRG]') and OBJECTPROPERTY(id, N'IsPrimaryKey') = 1)
ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG
AND I get this in return:
The command(s) completed successfully.
So, lets double check:
EXEC sp_pkeys @table_name = 'tblDRG'
,@table_owner = 'dbo' ,@table_qualifier = 'Relational_05Q3'
AND I STILL GET THIS:
TABLE_QUALIFIERTABLE_OWNERTABLE_NAMECOLUMN_NAMEKEY_SEQPK_NAME
Relational_05Q3dbotblDRGrecord_id1PK_tblDRG
Hmmmmm. Looks like the IF statement didn't do it's job. Ok fine. I'll just kill it myself:
ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG
AND I GET THIS?!?!?!?!
Server: Msg 3728, Level 16, State 1, Line 1
'PK__tblDRG' is not a constraint.
What am I not getting here? Is it me...I can take If I am a bone head here.
Any help would be appreciated. Thanks!

Here is my code,
1. create table t1 (id int )
2. create unique index u on t1(id)
3. create table t2 (id int constraint f foreign key references t1(id))
4. ALTER TABLE t2 NOCHECK CONSTRAINT ALL
5. ALTER TABLE t1 NOCHECK CONSTRAINT ALL
6. drop index t1.u
I get a FK voilation exception. on line 6.
I was not expecting this, because I am doing 4 & 5
Is dropping the FK is only option?
Actually I am trying to move the unique index to a different file group.

I need to use T-SQL to drop all instances of a particular object, no matter who the owner is. For example I might have two instances of a view named "test_view". One is owned by "dbo" and one is owned by "randomly_named_user". I do not know what the name of the owner of the second instance of the view, nor do I know how man instances of the view may exist. I need to drop all the views with the name "test_view".
Is there a way with T-SQL to drop all the instances of an object no matter who owns it? I understand I will need proper permissions to drop an object owned by someone else.
