docs: Updates the designated column with a <code>java.sql.SQLXML</code> value. The updater methods are used to update
  column values in the current row or the insert row. The updater methods do not update the underlying database;
  instead the <code>updateRow</code> or <code>insertRow</code> methods are called to update the database.
  <p/>
  
  @param columnLabel the label for the column specified with the SQL AS clause.  If the SQL AS clause was not
  specified, then the label is the name of the column
  @param xmlObject   the column value
  @throws java.sql.SQLException if the columnLabel is not valid; if a database access error occurs; this method is
  called on a closed result set; the <code>java.xml.transform.Result</code>,
  <code>Writer</code> or <code>OutputStream</code> has not been closed for the
  <code>SQLXML</code> object; if there is an error processing the XML value or the
  result set concurrency is <code>CONCUR_READ_ONLY</code>.  The <code>getCause</code>
  method of the exception may provide a more detailed exception, for example, if the
  stream does not contain valid XML.
