Oracle Error Message
PLS-00417: unable to resolve “string” as a column
Reason for the Error
A database table, view, or column was specified in a SQL statement that does not exist, or the privileges required to access the table or view were not granted.
Solution
Check the spelling of the table (or view) and column names; make sure the table and columns exist. If necessary, ask the DBA to grant the privileges required to access the table.
