Solution 1

you should make a reference between both tables on the same ID. So the childTable should have an int field that references to the parent table.

Solution 2

Both datatype should be same. Change child table id also to int or change main table id to varchar.

Solution 4

Foreign Keys (on child tables) must match the type of primary key (on the parent table).

So you cannot have varchar referencing int.
