Hi how can compare two rows in two diffrent table and return the columns and
his values that are not equal so for example i have table1 and table 2 that
has column sum, and vehid , in table1 the sum = 20 and vehid = 1 while in
table2 sum=20 and vehid = 2. so the output must return vehid as on those two
table are not equal??
