> Defect Tracker #18728: If the where clause processed by the XML connectors has an equivalence expression containing two columns (where col1 = col2), the expression will be ignored.  If the expression contains a column and a literal, it works properly.  Thus a workaround is to use a scalar conversion function to convert the column to a literal.  Something like substring(col1, 0) for string values or (col1 * 1) for numeric values.
