Searching a column containing CSV data in a MySQL table for existence of input values

Question

I have a table say, ITEM, in MySQL that stores data as follows:

ID    FEATURES
--------------------
1     AB,CD,EF,XY
2     PQ,AC,A3,B3
3     AB,CDE
4     AB         


        

Answer 1

Alternatively, consider using RLIKE()

    select * 
      from ITEM
     where ','+FEATURES+',' RLIKE ',AB,|,PQ,';
