Hi Ehsan,

You can do this as:

–Insert code
INSERT INTO TableA(columns)
SELECT Columns
FROM TableB b
WHERE NOT EXISTS(
SELECT a.Id
FROM TableA a
WHERE a.ID = b.ID
)

–Update code
UPDATE TableA
SET Columns = b.Columns
FROM TableA a
INNER JOIN TableB b ON a.ID = b.ID

Let me know if you have any questions.

@Ehsan.

What is the concern. You explained your scenario. But what is that you want from us.

You want us to write a script for you or are you looking for any solution from us on how you can implement your requirement.

Please briefly tell us what is that you want us to do ? what kind of help you are looking for.

@Sneha.

I am not aware of any direct way of doing this.

You could do this from SQL Server Management studio easily, but if you see Generate Script for this, you would see that
1. Your original table is copied into a temp table,
2. Original table is dropped and
3. A new table is created with column added with the specified column location and
4. Then data is copied from temporary table to this new table.
5. And then name of this new table will be renamed to your original table.

@Harish

I’m happy you could figure it out.

I always try making it one query if possible. I could not see it here, because a PROCEDURE is being used in the middle.

INSERT…SELECT is usually faster than a CURSOR. And as one query, everything will be in context too. And for many, it is much easier to read because all the logic is in one statement. It might be worth a bit of your time to review the entire process and see if it can be one statement.

@Brian, hmm i dont think so. But i was able to figure out my issue.

The correct one’s is:

DECLARE @MyCursor1 CURSOR
SET @MyCursor1 = CURSOR FAST_FORWARD
FOR
SELECT strength_app_men_inst_id from TACF_WFTA_STRENGTH_APP_MEN_INST where wf_task_assignment_id = @WfTaskAssignmentIDP1
OPEN @MyCursor1
FETCH NEXT FROM @MyCursor1 INTO @strength_app_men_inst_id
WHILE @@FETCH_STATUS = 0
BEGIN
exec @ReturnCode = getid_sel @table = ‘TACF_WFTA_STRENGTH_APP_MEN_INST’, @id = @NewID2 OUTPUT, @mode = 2
insert into TACF_WFTA_STRENGTH_APP_MEN_INST (id, wf_task_assignment_id, strength_app_men_inst_id) values (@NewID2, @WfTaskAssignmentIDP2, @strength_app_men_inst_id)
FETCH NEXT FROM @MyCursor1 INTO @strength_app_men_inst_id
END
CLOSE @MyCursor1
DEALLOCATE @MyCursor1

Thanks for checking out… Harish

@Harish

Is there a way top combine this into one statement?

INSERT INTO …. SELECT … FROM

By: Harish

Harish — Mon, 26 Oct 2009 02:57:57 +0000

FYI: in my test data, the select returns 2 values, but when i ran the query, i got only one row with @StrengthAppMenInstIDP1 as null, but it had a value.

Dont know where i am going wrong…

Hi pinal,

i have a problem inserting multiple records into a table. My code looks like this:

DECLARE @MyCursor CURSOR
SET @MyCursor = CURSOR FAST_FORWARD
FOR
SELECT strength_app_men_inst_id from TACF_WFTA_STRENGTH_APP_MEN_INST where wf_task_assignment_id = @WfTaskAssignmentIDP1
BEGIN TRAN t3
BEGIN
OPEN @MyCursor
WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM @MyCursor
INTO @StrengthAppMenInstIDP1
END
exec @ReturnCode = getid_sel @table = ‘TACF_WFTA_STRENGTH_APP_MEN_INST’, @id = @NewID2 OUTPUT, @mode = 2
insert into TACF_WFTA_STRENGTH_APP_MEN_INST (id, wf_task_assignment_id, strength_app_men_inst_id) values (@NewID2, @WfTaskAssignmentIDP2, @StrengthAppMenInstIDP1)
CLOSE @MyCursor
DEALLOCATE @MyCursor
END
IF @@error 0
ROLLBACK TRAN t3
COMMIT TRAN t3

the select statement returns multiple values and i have to insert that into the same table. i know cursor is not a good way, but my select statement will always return a max of 10 values. Can you please check where i am going wrong, or a better way.

Can you please help me with this as soon as possible. I would really appreciate this.

Thanks,
Harish

Hi Mitch,
Basically we have to use select * into for temporary tables.
We can use it to create basic structure with Data.
But if you want to create table with all details then first you have to create script for it.
GO Enterprise manager->right click on object ->Generate Script ->Create ->copy the script and use that script to create new object.
after then use insert statment with select.

I hope this will help you.

Thanks

Hi Rushi,
You are going right way. You have to use transaction.
while inserting records in child table first you have to find that that record is already exist or not ,if not then first store into one local variable and then add it into master table first and then add in child table.

I hope u will get it .

Thanks
