+===== Driver Specific Issues =====
+In ADOdb V5, the field type returned in [[v5:dictionary:metacolumns]] is the metaType, not the actualType. For more on this issue, see [[https://github.com/ADOdb/ADOdb/issues/184|This Thread]] on Github. This behaviour changed in Version 5.21, but a backward compatibility mode is provided:
+-----------------------
+<code php>
+$db = newAdoConnection('access');
+$db->metaColumnsReturnType = METACOLUMNS_RETURNS_META;
+</code>
+Depending on the database security, some meta functions may not be available. For more information, try this [[http://stackoverflow.com/questions/1937703/record-cannot-be-read-no-read-permission-on-msysobjects|Stack Overflow]] response.
