i have 2 table , want 2 columns each table. , want keep these total 4 columns 1 table.

example:-

s4, s5, s6 columns of table2

and want columns s1, s2, s4, s5 in table-3.

if there column in table1 , table2 can used join use:

select t1.s1, t1.s2, t2.s4, t2.s5  table1 t1, table2 t2  t1.column_for_join = t2.column_for_join
