Error Occured: Syntax Error(missing operator) in query Expression

Error Occured: Syntax Error(missing operator) in query Expression 

 Below Is The Code In Update Statement That Is Causing Error..

 OleDbCommand cmd = new OleDbCommand("UPDATE Vendor_Details SET Date1='" + CurrentDatePicker1.Text + "'"+

                "VendorName='" + txtVendorName.Text + "',AccountNumber='" + txtAcountNo.Text + "',Address='" + txtAddress.Text + "'"+

   "PhoneNumber='" + txtPhoneNo.Text + "',EMail='" + txtEMail.Text + "',Fax='" + txtFax.Text + "' WHERE VendorName='" + txtVendorName.Text + "'", con);

In The Above Statement While Concatenating The Statement With "+"  For Convenience To See The Code In Single Screen.I had Missed Commas(,) So The Error Is Occured.

After Modifiying The Update Statement Will Be Like This:

OleDbCommand cmd = new OleDbCommand("UPDATE Vendor_Details SET Date1='" + CurrentDatePicker1.Text + "',"+

                "VendorName='" + txtVendorName.Text + "',AccountNumber='" + txtAcountNo.Text + "',Address='" + txtAddress.Text + "',"+

   "PhoneNumber='" + txtPhoneNo.Text + "',EMail='" + txtEMail.Text + "',Fax='" + txtFax.Text + "'+

 WHERE VendorName='" + txtVendorName.Text + "'", con);

After Modifing Update Statement...I Got The Result Successfully
