+====== fetchObject =======
 ===== Description =====
+The ''fetchObj()'' / ''fetchObject()'' functions return the current row of a RecordSet as an ADOFetchObj object.
+They can be considered as aliases, except for the fact that ''fetchObject()'' converts the field names to uppercase by default, whereas ''fetchObj()'' does not.
+Unlike the [[v5:reference:recordset:fetchNextObj()]] method, the record pointer is not advanced. It is recommended that the 2 methods are not mixed in the same procedure.
+If the SQL statement results in an empty recordset or if the recordset has moved past end of file, then calling fetchObj() will return an empty record. Use [[v5:reference:connection:recordcount|recordCount()]] or check the EOF flag to ensure that you have retrieved a record.
+Results are influenced both by the [[v5:reference:adodb_assoc_case|ADODB_ASSOC_CASE]] constant and [[v5:reference:adodb_fetch_mode|$ADODB_FETCH_MODE]] attribute.
+The ADOFetchObj object has no special functionality, but the method is useful when the recordset data needs to be converted into e.g. JSON.
