Dropping Constraint On Temporary Table
Mar 20, 2007
I made a constraint on a temporary table in a stored procedure but now i can't delete it.
Here's what happened:
I ran this in a stored procedure
CREATE TABLE #TeFotograferen (RowID int not null identity(1,1) Primary Key,Stamboeknummer char(11) ,Geldigheidsdatum datetime, CONSTRAINT UniqueFields UNIQUE(Stamboeknummer,Geldigheidsdatum)
next time i ran the stored procedure it gave me
There is already an object named 'UniqueFields' in the database.
but since the temporary table is out of scope i cannot delete the constraint
I tried
delete from tempdb..sysobjects where name = 'UniqueFields'
and
declare @name
set @name=(SELECT name from sysobjects where id=(Select parent_obj from sysobjects where name='UniqueFields'))
drop table @name
giving me
Ad hoc updates to system catalogs are not allowed.
or
Cannot drop the table '#TeFotograferen__________________________________ __________________________________________________ _________________000000000135', because it does not exist or you do not have permission.

In Microsoft SQL Server, I have a documents table and a table whichcategorizes the documents, which we'll call categories.I tried running UPDATE statements on the categories table previouslyand I ran into a foreign key constraint. The error given was "UPDATEstatement conflicted with COLUMN REFERENCE constraint FK..."So I got rid of the Foreign Key relationship, and tried running anUPDATE statement against the categories table again.I'm now getting the following message:'Cannot UPDATE "categories" because "documents" exists.'There must be something hanging around maintaining that relationship,but I'm not sure where it would be found.I was thinking about dropping the table and then adding it back again,but I'm not entirely sure what that would do.Any help is appreciated in advance.thanks,Geoff

I think the answer to this question will be something like 'you'll have to re-initialize the subscribers', but I need to ask anyway...
I created a publication where my foreign key constraint we NOT created with NOT FOR REPLICATION. My publication is configured to replicate DDL changes. Is there any way I can drop and re-create the constraint in the publisher and get replication to push the change to the subscribers?
Thanks for your help

Hello Everyone,
I'm implementing a web-based Employee Self Service product that uses SQL Server as its backend. The product uses a fairly extensive data model which was automatically generated via a custom written schema.
I received a message from the vendor today that states that I need to ADD an additional field to an existing COMPOUND PK in one of their tables.
I wanted to check on one item before I DROP the existing 4 field PK and rebuild it as a 5 field PK.
Since the PK from the table in question is used as a FK in three other tables, will I be allowed to DROP then RECREATE the PK ?
If I do so, will it effect the FKs in the other 3 tables ?
Thanks in advance.
Mike

I am doing a data conversion in which I drop constraints before inserting data and then reapply at the end. I would like to also drop the not null constraints for certain columns, transfer the nulls and then fill them in later before reapplying the constraints. Is there a relatively simple way to drop and reapply the not null constraints?

I have a copy of this database table and the first thing I noticed was that the Primary Key was pretty much useless and there were no sensible indexes. Every query hitting this table ended up table scanning.So I thought I would try dropping the existing Primary Key constraint and then creating a more natural key that would make data retrieval quicker (hopefully). I understand that creating a clustered index on this table is going to take a long time as ALL the data will need to be reorganised (I estimate this will take at least 1 hour). However, just dropping the existing Primary Key constraint is taking forever.I can see that the server is doing a lot of disk reading/ writing and the wait type in Activity Monitor is PAGEIOLATCH_EX.I would have thought that just dropping a primary key would not change the data in the table, just delete the associated index.

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?

I am using a Stored procedure in which I am creating a table and dropping that table at the end of execution. This SP is calling every 10 second (but no concurrent access) from my application. Is there any issue using the drop table command in the SP? will it create any memory fragmentation issue in SQL server?

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.

I'm new to replication and would like to know how to drop an article published for replication. I believe I need to follow these steps, but I am unsure.
Step (1)
exec sp_dropsubscription @publication = N'db name',
@article = N'article name',
@subscriber = 'subscriber name',
@destination_db = N'db name'
Step (2)
exec sp_droparticle @publication = N'db name',
@article = N'article name'
Step (3)
drop the article on the publisher
Step (4)
drop the article on the subscriber
Is this the correct sequence or am I missing something.
Thanks, Dave

Hi Guys,
I am trying to DROP a table and recreate the table in a stored procedure and then I am trying to INSERT records into the newly created table in the same stored procedure.
I know I don't have to DROP the table, but I am trying to just get it to work. The process runs without error, but when I refresh the tables, the table I created isn't there. The T-SQL is as follows:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[ImportFilesPremier]
AS
DROP TABLE dbo.[PremierTest]
CREATE TABLE [PremierTest] (
[AYQ] nvarchar(6) null ,
[CYQ] nvarchar(6) null ,
[Description] nvarchar(50) null,
[PIP] [decimal] (17,2) ,
[BI] [decimal](17,2) Not null,
[PD] [decimal](17,2) Not null,
[COLL] [decimal](17,2) not null,
[COMP] [decimal](17,2) not null,
[DCRAT] [nvarchar](2) null ,
[Agent][nvarchar](3) null ,
) ON [PRIMARY]
begin transaction
insert into [PremierTest]
select *
from dbo.[new agt type tri 0804]
WHERE dir_ceded_ind = 'C'
commit transaction
Any information on how I can tweak my code so it works properly would be greatly appreciated. Thank you.

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!!

Apologies if this has been answered before, but the "Search" function doesn't seem to be working on these forums the last couple of days.
I'd just like to check if a table already exists before dropping it so that I can avoid an error if it doesn't exist. Doing a web search, I've tried along the lines of
"If (object_id(sensor_stream) is not null) drop table sensor_stream"
and
"If exists (select * from sensor_stream) drop table sensor_stream"
In both of these cases I get the error: "There was an error parsing the query. [ Token line number = 1,Token line offset = 1,Token in error = if ]"
Sooooo... what is the standard way to check for existence of a table before dropping it? Someone help? This seems like it should be simple, but I can't figure it out.
Thanks in advance!

I have to load and unload many datatabases for testing. So I wanted to quickly remove a database, its devices and respective dat files

Is there a way of completely dropping a database so that all trace of it is quickly gone?

For SQL 2005 transactional replication I have 1400 articles (tables, views, functions, sp) that are all replicated.
Will SQL 2005 allow me to drop a table from from the publication and drop it from the publication database that is referenced by exising views or sps that are replicated or does it somehow check that?

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.

I am trying to drop the "allow nulls" characteristics on an existing table

there ever be. How do I get rid of that "allow nulls" checkmark on an

I am finding it difficult to find an example that allows for insertion of additional rows into a table, without dropping the table I'm inserting into. Or inserting specific values. Like this example..
[URL] ....
I have 6 table I am formatting the data to conform to the final table as I'm inserting it into, but none of these examples gives me the example needed. I am using SQL 2012.
<code>
SELECT
CONVERT(VARCHAR(50),[FName]) + ' ' + CONVERT(VARCHAR(50),[LName]) AS [CustName]
,CAST('ALARMCOM' as nvarchar(8)) as VendorName
,CONVERT(VARCHAR(25),[CUSTOMER_CS_ACCOUNT_NUMBER]) AS [Cust_ID]
,CONVERT(VARCHAR(40),[Charge_Description])as [ChargeType]
,CASE
[Code] ....

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:

user_password
[second table]

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!
