query question using REGEXP

[award]

Hi,
 
I'm storing in a database  numbers separated by comma if more than one
number i.e
Record #       Column
1                                        12 
2                                        1,2,5,6
3                                        1,12,24,45
4                                         2,6
 
Now if I want to search for records that has number 1 it will find
records 1,2,3 
but what I want to return only record 2,3  
an example is that if I'm looking for a record that has a number 2 
it will print record 1,2,3,4 but what I want is only record 2,4 
 
Any help is appreciated,
anthony
