Question

I have Linq-to-SQL code here which submits data into the database in their respective table,
PatientInformation and ResponsibleParty:

public void addPatientInformation() { 
   using(DbClassesDataContext myDb = new DbClassesDataContext(dbPath)){
      PatientInfo patientInfo = new PatientInfo();

      patientInfo.Phy_ID = physcianID;
      patientInfo.Pat_First_Name = txtFirstName.Text;
      patientInfo.Pat_Middle_Name = txtMiddleName.Text;
      patientInfo.Pat_Last_Name = txtLastName.Text;
      patientInfo.Pat_Gender = cmbGender.Text;
      patientInfo.Pat_Marital_Status = cmbMaritalStatus.Text;
      patientInfo.Pat_Date_Of_Birth = dtpDOB.Value;
      patientInfo.Pat_Home_Add = txtHomeAdd.Text;
      patientInfo.Pat_Home_Num = txtPhone.Text;
      patientInfo.Pat_Work_Add = txtWorkAdd.Text;
      patientInfo.Pat_Work_Num = txtWorkPhone.Text;
      patientInfo.Pat_Prim_Physician = txtPrimPhysician.Text;
      patientInfo.Pat_Ref_Physician = txtRefePhysician.Text;

      myDb.PatientInfos.InsertOnSubmit(patientInfo);
      myDb.SubmitChanges();
   }
}

public void addResponsiblePartyInformation() { 
   using(DbClassesDataContext myDb = new DbClassesDataContext(dbPath)){
      ResponsibleParty responsibleParty = new ResponsibleParty();

      responsibleParty.Res_First_Name = txtResFirstName.Text;
      responsibleParty.Res_Middle_Init = txtResMiddleName.Text;
      responsibleParty.Res_Last_Name = txtResLName.Text;
      responsibleParty.Res_Gender = cmbResGender.Text;
      responsibleParty.Res_Marital_Status = cmbResMaritalStatus.Text;
      responsibleParty.Res_Date_Of_Birth = dtpResDOB.Value;
      responsibleParty.Res_Home_Add = txtResHomeAdd.Text;
      responsibleParty.Res_Home_Num = txtResPhone.Text;
      responsibleParty.Res_Work_Add = txtResWorkAdd.Text;
      responsibleParty.Res_Work_Num = txtResWorkPhone.Text;

      myDb.ResponsibleParties.InsertOnSubmit(responsibleParty);
      myDb.SubmitChanges();
   }

And a method named

public void submitInformationToDatabase() {
            addPatientInformation();
            addResponsiblePartyInformation();
            MessageBox.Show("Patient Demographics Has Been added.");
        }

Is there a way I could submit them at once?

Answer 1

If you can refactor your code to something resembling the example below, then both records will be inserted in the same submit.

using(DbClassesDataContext myDb = new DbClassesDataContext(dbPath)){

      myDb.PatientInfos.InsertOnSubmit(patientInfo);
      myDb.ResponsibleParties.InsertOnSubmit(responsibleParty);
      myDb.SubmitChanges();
}
