String ResultSetMetadata.getQualifiedName(
    int column_no
) throws ULjException

Null if there is no qualified name for the column; otherwise, returns the qualified name for a column.

When the ResultSet column refers to a column in a table, the name returned is a compound name consisting of a correlation name (or table name if the correlation name was not given) followed by the name of the column in the table.

When the ResultSet column does not refer to a column in a table and an alias was specified, the alias name is returned.
