Oracle/PLSQL: ORA-01446 Error
ORA-01446: cannot select ROWID from view with DISTINCT, GROUP BY, etc.
Cause of Error
The option(s) to resolve this Oracle error are:
Since the DISTINCT or GROUP BY causes the records in the view to not correspond directly to the underlying physical records, the ROWID values can not be returned.
Either remove the DISTINCT or GROUP BY clause,
Remove the ROWID column from the the SELECT statement.
