hi all ,
I really need your help. I connect to oracle db with input tool which contains a string of sql:
when select count(*) from table A, the result is : 48067.
when select * from table A, the input tool is always 0% and won't stop.
i executed the sql in db, it works but the rows of result was 6878, count result was 6878.
does anyone have any idea what's wrong with the db?
