'my_site_orders.order1_type! = my_site_products.product_select1 {1..10}'때문에 my_site_orders.order1_type에 공통 값이 없습니다. my_site_products.product_select {1..10} – ajreal

[normalizing] (http://en.wikipedia.org/wiki/Database_normalization) 테이블을 고려하셨습니까? – NullUserException

데이터베이스 구조가 잘못되었습니다. "product_image5"또는 "product_select9"라는 필드를 creatin 할 때 뭔가 잘못되었다는 것을 알아야합니다. –

첫째, 당신은 많은 관찰 보고서 대신 IN()를 사용할 수 있습니다. 쿼리가 더 짧아지고 읽기 쉬워집니다. 다음으로, order1_type IN(product_select1,product_select2,product_select3,product_select4,product_select5,product_select6,product_select7,product_select8,product_select9,product_select10)으로 주문이없는 것은 분명합니다. 첫 번째 쿼리의 일부 샘플 데이터는 쿼리를 올바르게 다시 작성하는 데 도움이 될 수 있습니다.
