Insert data problem
-
Hi all,
I inserted 35,000 records into a table and created a locking in that table. Is there anyway to overcome this.
Thanks,

My goal is to add an identity field so that I instruct my query to insert 1000 record at a time, but I don't know how. Please rescue me.
Thanks,

No offense but inserting only 35k records shouldn't take long. How large is the table?
How many indexes are there on the table?
What's the Primary/key, clustered index?
How long does it take to do the select?

Remi not only do you type answers to questions faster than I do but you type questions to questons faster than I do.

Yup
.And I just thaught of a few more :
How many relations do you have on that tables?
Do you have insert triggers?
Do you have a lot of check/default constraints?
What are the specs of the server?
Is tempdb big enough?
Is the target db big enough (autogrow problems)?
-
I don't have any relations on the tables, no insert triggers eithere. My server is good enough. The think is I insert data from a link server.
insert into [122.23.23.2].ed.dbo.product_inventory
select * from tmp_product_inventory.
I tried to add id field in my tmp_table and write a loop to insert 500 records at a time. When I insert 500 records at a time, it did not create a lock. Please show me how to write a loop.
select *, identity(int,1,1) into mytemp from tmp_product_inventory
declare @id
set@id =1
While @id<>0
Begin
set @id =@id+500
insert into [122.23.23.2].ed.dbo.product_inventory
end
But it did not work.
Thanks,

Just go to the linked server and do the insert from there... It's gonna be faster that way... and won't take a loop.
-
I really like to know to do the looping. Can you give me an example?

Sorry for the delay :
DECLARE @Demo table (RowID int not null identity (1,1) primary key clustered, name varchar(10) not null)
Insert into @Demo (Name)
Select 'cats'
UNION ALL
Select 'dogs'
UNION ALL
Select 'birds'
UNION ALL
Select 'chimps'
UNION ALL
Select 'zebras'
Select * from @Demo
DECLARE @LastID as int
DECLARE @CurID as int
DECLARE @Name as varchar(10)
SET @LastID = 0
SELECT TOP 1 @CurID = RowID, @Name = Name from @Demo order by RowID
WHILE @CurID IS NOT NULL
BEGIN
SET @LastID = @CurID
SET @CurID = NULL
PRINT @Name
SELECT TOP 1 @CurID = RowID, @Name = Name from @Demo where RowID > @LastID order by RowID
END

Several things wrong with your SQL:
select *, identity(int,1,1) AS ID into mytemp from tmp_product_inventory
declare @id INT
set@id =0
While @id<= (SELECT MAX(ID) FROM mytemp)
Begin
set @id =@id+500
insert into [122.23.23.2].ed.dbo.product_inventory
select col1, col2, ... from mytemp
where id > @id - 500 and id <= @id
end
Really, if you do it from the destination server it should be faster. Or, I'd use DTS which would do a bulk insert.

Thanx for the x rows at the time version... didn't want to write a 2nd versions
