Hey, how to make a sql, I want to add a line each time when map changes,

But I want to make max 20 lines in sql, so that the last lines disappear...

For example, I've 20 lines

1. aa
2. bb
...
...
18. cc
19. dd
20. ee

When 1 line adds the 19 (was dd now cc) line became 20 (was ee now dd) and 20 (which one was ee) disappears...

I hope u understood me because I don't know how to explain it ;D
