推荐答案

，您应该在同一ID的两个表之间进行引用.因此childTable应该有一个引用父表的int字段.

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.

两个数据类型都应该相同.还将子表ID也更改为int 或将主表ID更改为varchar.

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

更改列的数据类型
