GROUP BY returns single occurence of a row. However I need to limit it to a specified number of occurences.

Suppose the tabe has the following:

number letter

100 A
100 A
100 A
200 B
200 B
200 B
200 B

….and I need this to limit to say 2 occurences…the output should be…

100 A
100 A
200 B
200 B

….so on for each of the multiple rows in the table..

Can you please direct me to the right query?
