SELECT TOP M * from Table ....
Such SQL statements are accurately understood to take M strip data.
I don't know if you have encountered this situation.
You give M = 1 ~ 9 it appears. But if you give 11 ~ or more, it will be wrong.
For example,: m = 11 It will appear 19.
If you have a friend who has encountered this phenomenon, I welcome to discuss it. Thank you.
