"i have a statement level trigger and row level trigger on the same table"

Not that we can see.

"here is what will be the output?"

We have no idea...we can't even see the table or the trigger...

"which trigger will execute ist and why and how ?"

Probably the statement one...but you provided no code, no test case, no details... so its a mystery.

"what will be the output if i will write a select query ?"

Depends on the query probably. If you write

select 1 from dual

you will get "1" back.

If you write

select username from dba_users where user_id = 0

then you will get "SYS" back

But you're not limited to just those queries...


Sigh
