 ===== Description =====
-The function ''metaType()'' accepts as an argument a database specific datatype, usually the result of a call to [[v5:reference:recordset:fetchfield|fetchField()]] and returns an ADOdb datatype, which provides a mapping to allow cross-database compatibility. The compatible fields are explained [[v5:dictionary:dictionary_index#Summary_Of_Types|Here]]
