Question

所以我有以下SQL语句：

db.exec("UPDATE products SET product_description = '#{fj_description}' AND personalization = '#{fj_personalization}' AND product_photo = '#{fj_product_photo}' AND order_information = '#{fj_order_information}' WHERE campaign_name = '#{camp_name}' AND product_type = 'fleecejacket'")

所有变量都返回从HTML输入字段中检索到的正确文本，因此sql语句似乎有问题。当我尝试更新数据库时，出现此错误：

PG::InvalidTextRepresentation at /update_products
ERROR: invalid input syntax for type boolean: "soft, midweight fleece" LINE 1: UPDATE products SET product_description = 'soft, midweight f... ^

Answer 1

尝试使用逗号代替AND：

"UPDATE products 
 SET product_description = '#{fj_description}',
   personalization = '#{fj_personalization}',
   product_photo = '#{fj_product_photo}',
   order_information = '#{fj_order_information}' 
 WHERE campaign_name = '#{camp_name}' 
 AND product_type = 'fleecejacket'"

SQL语句用多个where条件更新多个列
