所以我有如下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... ^
最佳答案
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'"
关于html - SQL语句用多个where条件更新多列，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44810513/
