SQL查询 - 从逗号分隔的一列中获取数据

Question

Hi I have problem with fetching data from one column separated with comma,

My problem is:

 Table1               
 ID | Cat          
--------
 1  | XY

 2  | ER

 3  | FF

Table2               
Id | Text | Text2 | Table1ID | Text3 | text3          
--------------------------------------------------
1  |  --  |  --   | 1,2,3    |  ---  | ---

2  |  --  |  --   | 3,1,2    |  ---  | ---

3  |  --  |  --   | 1,3,4    |  ---  | ---

I need SELECT query to fetch data from Table1 column Cat where Table1.ID=Table2.Table1ID and i got only one Cat but i need all from Table2.Table1ID

This is my query now:

SELECT * FROM Table2, Table1 
        WHERE Table2.Table1ID=$ID 
        AND Table2.Table1ID=Table1.Id
        AND Table2.Table1ID

I only got one data from Table1ID and everything behind comma is invisible

thx for help

Answer 1

Well, sorry then. I misunderstood your explanation.

May not the better way but it may works:

SELECT * FROM Table2 WHERE Table2.Cat Like '%$ID,%' OR Table2.Cat Like '%,$ID'

Answer 2

SELECT * FROM Table2, Table1 
        WHERE Table1.Id=$ID 
        AND FIND_IN_SET(Table1.Id, Table2.Table1ID) <> 0
