How to insert values in two relational tables?

I have created four tables which all are related to each other as follows:

Table 1: Project

PrjID (Primary key) and ProjectTitle

Table 2: Student

StdID(Primary key) PrjID(Foreign Key) and StdName

Table 3: Course

CrsId(Primary key) and CourseTitle

Table 4: Teacher

TchID(Primary Key), CrsID(Foriegn Key), StdID(Foreign Key), YearSemester, NoOfSection, LabHours, and NoOfStudents.

What will be the SQL query to insert values in these all tables at a time or individually without any kind of conflict? waiting reply its too much important please
