what is the output of the query select * from emp where 1=2
Answer Posted / ganesh
for sure it will display no rows selected
coz for select * from emp give all and because of the where
clause 1=2.......no point in time 1 is eual to 2 or 2 is
equal to 1....so it returns no row.
eg 1=2 ----give no rows
1=1 ---gives all rows
come out of oracle and think as simple logic (is 1=2)....if
yes true else false.....similar of oracle also
