>          Components: SQL
>    Affects Versions: 2.1.0

> Current "CREATE TEMPORARY TABLE ... " is deprecated and recommend users to use "CREATE TEMPORARY VIEW ..." And it does not support "IF NOT EXISTS" clause.  However, if there is an existing temporary view defined, it is possible to unintentionally replace this existing view by issuing "CREATE TEMPORARY TABLE ... " with the same table/view name.
