Dropping Statistics From User Tables
Apr 21, 2008Hi,
I have founde such a nice code to create statements for dropping all statistics in a database.
DECLARE @tblname sysname, @statname sysname, @sql nvarchar(2000)
DECLARE c CURSOR FOR
SELECT object_name(id), name FROM sysindexes WHERE INDEXPROPERTY(id, name, 'IsStatistics') = 1
OPEN c
FETCH NEXT FROM c INTO @tblname, @statname
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'DROP STATISTICS [' + @tblname + '].[' + @statname + ']'
PRINT @sql
FETCH NEXT FROM c INTO @tblname, @statname
END
CLOSE c
DEALLOCATE c
Please help me with changing this code to take care only on indexes from my own tables (no system ones).
Thanks for your help.

Auto Created Statistics And Missing Statistics
Jul 20, 2005Hello group.I have an issue, which has bothered me for a while now:I'm wondering why the column statistics, which SQL Server wants me tocreate, if I turn off auto-created statistics, are so important to theoptimizer?Example: from Northwind (with auto create stats off), I do the following:SELECT * FROM Customers WHERE Country = 'Sweden'My query plan show a clustered index scan, which is expected - no indexexists for Country. BUT, the query plan also shows, that the optimizer ismissing a statistic on Country, which tells me, that the optimizer wouldbenefit from knowing this.I cannot see why? (and I've been trying for a while now).If I create the missing statistics, nothing happens in the query plan (andwhy should it?). I could understand it, if the optimizer suggested an indexon Country - this would make sense, but if creating the missing index, queryanalyzer creates the statistics with an empty index, which seems to me to beless than usable.I've been thinking long and hard about this, but haven't been able to reacha conclusion :) It has some relevance to my work, because allowing theoptimizer to create missing statistics limits my options for designingindexes (e.g. covering) for some rather wide tables, so I'm thinking why notturn it off altogether. But I would like to know the consequences - hopesomebody has already delved into this, and knows a good explanation.RgdsJesper

Aug 1, 2006What is the unit of the numbers you get in the Time Statistics-part when running a query in Microsoft SQL Server Management Studio with Client Statistics turned on?
Currently I get mostly 0īs, but if I try and *** up a query on purpose I can get
it up to around 30... Is it milliseconds or som made up number based on clockcycles or... ?
I would also like to know if itīs possible to change the precision.

Dropping Tables
May 28, 2002Is there a way we can prevent a object owner from dropping his tables. Example:
There is a user called 'tom' who is given create table permissions, 'tom' creates the table completes his dev and then the table is moved into production where 'tom' is still the owner. However, in production, 'tom' does not have the create table privs. Because 'tom' is the owner of the table, he is still able to drop the table in production. This is what I am trying to avoid. I would like to retain 'tom' as the owner and want to take away his create/drop privs.

Dropping All Indexes
Jan 3, 2007Looking for suggestions.
I have a database that is giving me a bad Index error. When I go to drop the necessary Index it is telling me that it either does not exist or cannot be dropped. However when I try to build that index, it tells me one already exists.
Is there any way to drop all of the indexes or at the very least see what the indexes are? This particular database is using 2005 Express.
Any help would be great!

Dropping Constraints
Oct 15, 2007How to remove the constraints on a table in sql server 2000? I need to drop the column, so i need to drop the constraint before that.
Alter Table Table_Name NO CHECK constraints ALL.
Once I execute the above one, it says, "Successfully Executed" but when I try to drop it doesnt allow me and gives me the following error:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF_Users_Created_by' is dependent on column 'CREATED_BY'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE DROP COLUMN CREATED_BY failed because one or more objects access this column.
Any ideas?

Dropping A Constraint

Trigger Dropping
Apr 12, 2006Hi:
I think I am doing something wrong. I am trying to make the trigger fire when I want to drop the same trigger. For example I have the following trigger defined:
USE AdventureWorks2000
GO
CREATE TRIGGER Incheckstock
ON DATABASE
FOR DROP_TRIGGER
AS
PRINT 'You must disable Trigger "Incheckstock" to drop Trigger!'
ROLLBACK
GO
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
ENABLE TRIGGER Incheckstock ON DATABASE
DROP TRIGGER Incheckstock
ON DATABASE
I created the trigger Incheckstock and i want to see if the same trigger fires itself if when i am trying to drop the trigger with the same name (kind of recursive one). Is this possible in SQL 2005?. If I asked a dumb question, please correct me.
Thanks

May 14, 2002I guess nobodys heard of this? I'm using DTS to transform data to Excel spreadsheet. I have a DROP TABLE `data$` then a CREATE TABLE `data$` the old data is cleared but the new data is appended to the blank rows of the old data. So if I had 5 rows before now I have 10. And the new data has 5 blank rows before it.
I've tried deleting the excel file & replacing it with a new one.
I've used the wizard thinking it was me but no good, it still happens.

Replication - Dropping A Table
Nov 22, 2002I'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
