บอกผู้มีอำนาจที่มีเดไซล์น้อยกว่า 6 และหมุนน้อยกว่า 65 ไม่จำเป็นต้องใช้ทุกตาราง
tell me the authority that has a decile less than 6 and roll less than 65.It is not neccessary to use all the tables.
 table_68263:  "Name" [ text]  "Years" [ text]  "Gender" [ text]  "Area" [ text]  "Authority" [ text]  "Decile" [ real]  "Roll" [ real] 
SELECT "Authority" FROM table_68263 WHERE "Decile" < '6' AND "Roll" < '65'
