In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question:

"Indicates whether the designated column can be used in a where clause."

I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter).

Are there any other cases?
