Should refer to Oracle Error Manuals.
Most of your posts are subjected "URGENT". I suggest you to take some time off and go through the manuals.
For a quick reference you can check the error details here
dont expect fast response just you say urgent!
the time you spend writing here you can use it to find the error code! it only takes a couple of minutes to search for error code on tahiti.oracle.com
TO FIND OUT ERROR FROM SQL PROMPT ONLY I MEAN REASON FOR THAT ERROR
Ok...... here is the piece from Oracle Error Manual
ORA-01740 missing double quote in identifier
Cause: An initial double quote (") was found without a closing quote. If an identifier contains a blank or special characters other than $, #, or _, it must be enclosed in double quotes.
Action: Add a closing double quote (") to the end of the identifier
Perhaps "show errors" helps you ... if you use SQL*Plus.
If u r in Unix environment, Pl try the below at SQL prompt:
SQL> !oerr ora errornumber
ex: !oerr ora 03113
