I am creating menu and submenus in a table variable. ( Typical parent child records in the same table)
ParentID coll is null for all Top menus. And for their child ParentID will be the MenuId of these parent menus. ( Depending on what kind of user logs this is build )
Now what I have to do is if particular parent doesn’t have any child I want to delete this parent recrod from this table variable.
I know I can to it with cursor or by row by row operation. Can I do it any other way?

    Without seeing your table structure it’s difficult to tell you the exact query you would need but, if I understand your question correctly, you just need to do something like this:

    DELETE T 
FROM MyTable T 
WHERE NOT EXISTS(SELECT * FROM MyTable WHERE ParentID = T.MenuID)
    AND T.ParentID IS NULL

    This query does a correlated subquery to find all the menu records that don’t have child records. It uses SQL’s EXISTS clause
