-===== Constants =====
+If you have multiple connection objects, and want to have different fetch modes for each connection, then use SetFetchMode. Once this function is called for a connection object, that connection object will ignore the global variable ''$ADODB_FETCH_MODE'' and will use the internal fetchMode property exclusively.
