จอห์นนี่ วิลเลียมสันหรือดิ๊ก แมคโกเวนเป็นโค้ชในปี 1952 หรือไม่?ไม่จำเป็นต้องใช้โต๊ะทั้งหมด
was johnny williamson or dick mcgowen the coach in 1952 ?It is not neccessary to use all the tables.
 table_203_593:  id [ number]  "tenure" [ text]  "coach" [ text]  "years" [ number]  "record" [ text]  "pct." [ number] 
SELECT "coach" FROM table_203_593 WHERE "coach" IN ('johnny williamson', 'dick mcgowen') AND "tenure" <= 1952 AND "tenure" >= 1952
