I am using one parent table and one child table.While saving the parent table child table also get saved.ie.In parent table while saving one row,more than one row (say 3 rows) are saved in child table according to my project.The problem is while updating the record,If I am setting only 2 rows in child table means,it is not getting updated in the db.All the 3 rows which was inserted while saving the record are there in db.How to update the child table in this case??
