Hello Code Gurus,

               Can you please help me regading following problem?

TABLE1:

studentID(PK)
studentName

TABLE2:

studentID(FK)
studentMarks

These two table has one-to-one relationship.Now how to insert data into two tables simultaneously?Is it possible with one SQL statement?

Thanks in Advance.

I think you mean one to many? Table2 would have these fields:

TABLE2
Table2ID
studentID(FK)
courseID(FK)
studentMarks

This would make it a junction table, and therefore you have a many-to-many relationship.

If you want to insert into Table2, you will want to have the studentID AND the courseID. You can take these on a form, and then you would have a grade selection as well on the form. If these were all combos (including the grade - value list) then you would do this:

Dim iStud As Integer
Dim iCourse As Integer
Dim sGrade As String
Dim sSQL As String

iStud = Me.cboStudent
iCourse = Me.cboCourse
sGrade = Me.cboGrade

sSQL = "INSERT INTO Table2(studentID, courseID, studentMarks)" & _
       " VALUES(" & iStud & ", " & iCourse & ", '" & sGrade & "')"

DoCmd.RunSQL(sSQL) etc

If you want to create a student and a course and a grade all at one time, that is a little more problematic. Did this help?

Thanks mmcdonal for ur reply.

But my both tables have one-to-one relationship. And I want to insert data into both tables simultaneously. For example.

For Table1-(S0001,Mr.John)
For Table2-(S0001,60%)

I want to insert above data using one SQL statement,so that both data will be inserted at the same time.Is it possible? Please help.

Data normalization issues aside, you will probably have to use two transactions since there may not be a StudentID PK when you do this all at once. Is it a problem to do this in two steps in one sub?

Like:

"INSERT INTO Table1(studentID, studentName)" & _
       " VALUES(" & iStud & ", '" & sSName & "')"

"INSERT INTO Table2(studentID, studentMarks)" & _
       " VALUES(" & iStud & ", '" & sGrade & "')"
