通过查询从前端将数据插入外键

Question

我正在尝试通过Nodejs将数据（发布方法）从Angular传递到Postgresql。如何在插入查询中从前端（动态）插入外键值？

query1:
 INSERT INTO tab_student (name_student, id_teacher_fk)
 VALUES ('abc', 
       (SELECT id_teacher FROM tab_teacher WHERE id_teacher_pk = ? )
//how do we get the foreign key id_teacher_fk from frontend 

 query 2:
INSERT INTO tab_student (name_student, id_teacher_fk)
VALUES ('rich man', LAST_INSERT_ID())
