Question

Assume my table column contains the following 2 string rows:

       1, 5, 2, 31, 12, 1212, 111
       21, 25, 32, 43, 112, 212, 311

I need a query to select a row that contains number 1 and contains number 2

My Query is:

      SELECT *
      FROM MyTable
      WHERE My_String LIKE '%1%' AND My_String LIKE '%2%'

now this returns both of the rows when i want it to return only the first row.

It selects second row because numbers 21, 25, 32, 112, 212, 311 also contain number 1 and 2.

My question is how do i select all those rows where numbers 1 and 2 are contained in a string but not in 2-3 digit numbers. I want it to match strictly to those 1 and 2

select * from testtable
where instr(concat(', ', longstring, ', '), ', 2,') >0;

select * from testtable
where instr(concat(', ', longstring, ', '), ', 1,') >0 
and  instr(concat(', ', longstring, ', '), ', 2,') >0;
