记录一次sql查询方法，判断值是否存在FIND_IN_SET

SELECT location_code,position_type FROM 
(SELECT 
CASE WHEN location_code IS NULL THEN 0 ELSE 1 END location_code,
CASE WHEN position_type IS NULL THEN 0 ELSE 1 END position_type
FROM  `ks_container` WHERE  position_type='common_shelf' AND container_code IN    
 (SELECT  `container_code` FROM `ks_sub_container` WHERE id IN (SELECT ks_sub_container_id FROM ks_stock WHERE sku_code IN ('pandian_sku_1sub')))) t 
 WHERE  FIND_IN_SET(1,location_code) AND  FIND_IN_SET(1,position_type)
