使用PHP在mysql中搜索base64编码字符串的子字符串

Question

i am trying to find out possible solution to search sub strings from base64 encoded string from MySQL i am storing title of the product in base64 encoding for example Ricoh SP 212W as Umljb2ggU1AgMjEyVw==

and now i want to search all products with a possible string "SP" but how i can search "SP" in Ricoh SP 212W because this is stored as base64 encoding

this is what i am trying

Select * from `prducts` where `product_name` LIKE %SP%

but as i already mention product_name is stored in Base64 encoding

any suggestion please

Answer 1

Select * from prducts where FROM_BASE64(product_name) LIKE %SP%

为什么甚至将产品名称存储在base64中？
