Query with multiple values in a column

Question

I have a table like:

id     name            children
1      Roberto         Michael,Dia
2      Maria           John,Alex
3      Mary            Alexandre,Dia         


        

Answer 1

I would rather make different tables for children and parents something like this.

Table for parents

parent_id     name            
1             Roberto         
2             Maria           
3             Mary     

Table for children

children_id  parent_id  name
1            1          Michael     
2            1          Dia 
3            2          John

.... and so on
