Question

I want to delete table rows from xyz table where row count should be greater than 10, but I don’t have any column that holds row position. I don’t want to add additional column such as Id. Here is my table structure:

name(as text)  subject(as text)  filename(as text)

and here is my query which deletes entire table

delete from questions where (select Count(*) from questions)  between  10 and 20

I am not getting what to write instead of (select Count(*) from questions)

any solutions?

Answer 1

I think this would work:

DELETE FROM table WHERE name NOT IN (SELECT TOP 10 name FROM table)

This is assuming that name is unique.
