มีจำนวนเซ็นเตอร์เท่ากันกับตำแหน่งอื่นในทีม ?ไม่จำเป็นต้องใช้โต๊ะทั้งหมด
there are the same number of centers as what other position on the team ?It is not neccessary to use all the tables.
 table_204_140:  id [ number]  "round" [ number]  "#" [ number]  "player" [ text]  "position" [ text]  "nationality" [ text] 
SELECT "position" FROM table_204_140 WHERE "position" <> 'center' GROUP BY "position" HAVING COUNT(*) = (SELECT COUNT(*) FROM table_204_140 WHERE "position" = 'center')
