Hi,
Oracle 12cR2
SQL Developer, version 17.2.0
No linked database involved.
PLS-00352: Unable to access another database 'AOL.NET'
ORA-06550: line 57, column 24:
PLS-00201: identifier 'G@AOL.NET' must be declared
This message is returned after entering an email address; i.e. first_name.last_name@provider.com as a VARCHAR2 parameter in a function, because the PL/SQL interface in SQL Developer
does not add single quotes around the string. You can see the envelope icon outside the quotes.
Maybe a bug in this SQL Developer version?
