I have a column in table "recipes" called "Products". 我在“食谱”表中有一列称为“产品”。 This is is filled like this: 这样填充：

460,450|50,100|243,500|141,5|457,100|383,211|

ProductID,ProductGrams| 产品ID，ProductGrams | is the format. 是格式。

Now i would like to search for an product with id 243 in the above example. 现在，我想在上面的示例中搜索ID为243的产品。 How can i do this? 我怎样才能做到这一点？

SELECT * FROM recipes WHERE Products LIKE '%243%'

Will also give me results if theres productgrams that are 243. 如果productgrams是243，也会给我结果。

How can i do this? 我怎样才能做到这一点？ Im lost... 我迷路了...

Its ok if theres also php for a solution to this. 好的，如果还有php可以解决这个问题。

Answer 1

You could do 你可以做到

SELECT * FROM recipes WHERE Products LIKE '243,%' OR Products LIKE '%|243,%

But more importantly this data should be normalized in the database prior to being queried. 但更重要的是，应在查询之前在数据库中对这些数据进行规范化。

Answer 2

只需按自己的喜好包含分隔符，

SELECT * FROM recipes WHERE Products LIKE '%|243,%'

Answer 3

Maybe tthis will work? 也许这行得通吗？

SELECT * FROM recipes WHERE Products LIKE '%243,%'

Note the comma. 请注意逗号。
