Check if all record columns of 2 Tables/Query are equal
I think this will work:

SELECT CASE WHEN NOT EXISTS
         ( SELECT * FROM table1
           EXCEPT 
           SELECT * FROM table2
         ) 
             AND NOT EXISTS 
         ( SELECT * FROM table2
           EXCEPT 
           SELECT * FROM table1
         ) 
         THEN 'True' ELSE 'False'
       END AS result ;
