ORA-00942: Table or view does not exist

What it means

The object is missing, is in another schema, or you do not have a privilege on it (Oracle reports missing privileges as "does not exist" so it does not reveal the object). In PL/SQL, privileges granted through a role are not visible inside definer-rights stored code.

How to fix it

Check ALL_OBJECTS for the name and owner, prefix it with the schema or create a synonym, and grant SELECT/INSERT/... directly to the user (not through a role) when the object is used inside a procedure or package. Watch for quoted lower-case table names.
