3.4
78.9
But I want to get result like this:

回答1:
If you want 78.9 to be 78 then
SELECT Floor(A/B) FROM table
If you want 78.9 to be 79 then
SELECT Ceiling(A/B) FROM table

Just ROUND your result:
SELECT ROUND(A/B, 0) FROM table
You can also combine ROUND with FLOOR if you always want to round down.
