I wish this help you I'm running the following query on SQL Server: , Any NULL's in the sub-query?
Try and re-write as
code :
delete from thisTable 
where id not in (select theID 
                 from thatTable 
                 where theID is not null)
delete from thisTable 
where not exists (select * from thatTable
                  where thisTable.id = thatTable.theID)

SQL Server 2008 Query to Delete All Rows Where Values Are Not Found in 3 Other tables

SQL Server 2008 Query to Delete All Rows Where Values Are Not Found in 3 Other tables

help you fix your problem I am working on a SQL Server 2008 database where all items that can be used in the database are stored in table A with a key value of ItemNum. Table B and Table C use ItemNum as a key value and are where the items from table A are actually used. Table A contains many duplicates that aren't used in Table B and Table C. I need to delete all ItemNum from Table A that are not used in tables B or table C. , You could use a simple DELETE JOIN;
code :
DELETE A FROM A 
LEFT JOIN B ON A.itemnum = B.itemnum
LEFT JOIN C ON A.itemnum = C.itemnum
WHERE b.itemnum IS NULL
  AND c.itemnum IS NULL;

may help you . I have two tables: , You can add ON DELETE CASCADE to your foreign key constraint;

This might help you If you can SELECT A.*, then you can also DELETE A. The conditions of the JOIN you have created should simply ensure that what is being deleted is only those rows that would have been returned from the SELECT.
I'm assuming that your ROLLBACK is because you're testing, so you simply copy your SELECT statement to be after the DELETE and check to see what's returned.

To fix the issue you can do ROW_NUMBER() OVER (PARTITION BY Name ORDER BY Name) doesn't make a lot of sense. You wouldn't ORDER BY the same thing you used in PARTITION BY since it will be the same value for everything in the partition, making the ORDER BY part useless.
Basically the CTE part of this query is saying to split the matching rows (those with [Id] = 2170) temporarily into groups for each distinct name, and within each group of rows with the same name, order those by name (which are obviously all the same value) and then return the row number within that sequence group as RN. Unique names will all have a row number of 1, because there is only one row with that name. Duplicate names will have row numbers 1, 2, 3, and so on. The order of those rows is undefined in this case because of the silly ORDER BY clause, but if you changed the ORDER BY to something meaningful, the row numbers would follow that sequence.

this will help Your trigger is only changing one row. In SQL Server, triggers are set operations, so you should be thinking as sets:
code :
ALTER TRIGGER [dbo].[TrgDltDate] ON [dbo].[Date] INSTEAD OF DELETE
AS
BEGIN
    UPDATE dbo.Date
        SET DLT = 1,
        LastModificationDate = GETDATE()
    WHERE DateID IN (SELECT d.DateID FROM Deleted d)
END;
