3개의 참조괸 테이블에서의 insert 방법좀 가려쳐 주세여
우선 키는 order_no 입니다
[나의 생각]
with query2 do begin
close;
sql.clear;
sql.add('insert into users(order_no,order_name,receive_name,receive_tel1,receive_tel2,receive_zip,receive_add,vendor)');
               sql.add('values('''+a1+''','''+a2+''','''+a3+''','''+a4+''','''+a5+''','''+a6+''','''+a7+''','''+x+''')');
               execsql;
             end;
             with query3 do begin
               close;
               sql.clear;
               sql.Add('insert into item(order_no,item,qty,service_item)');
               sql.add('values('''+a1+''','''+a8+''','''+a9+''','''+a10+''')');
               execsql;
             end;
             with query4 do begin
               close;
               sql.clear;
               sql.Add('insert into printe(order_no)');
               sql.add('values('''+a1+''')');
               execsql;
             end;
             gauge1.Progress :=i;
             application.processmessages;
             frmchange.caption:='Excel data를 DB로 저장중입니다..';
           end;//for
