Something like

Select file1.empno, file1.swipedate , file1.time1, file2.time2, file3.time3, file4.time4 from table1;
   inner join table2 on table1.empno=table2.empno;
   inner join table3 on table1.empno=table3.empno;
   inner join table4 on table1.empno=table4.empno

If all the tables have an index tag on empno, the join should be superfast.
