Remarks

Some field names, although valid in ArcGIS, conflict with internal properties used by ArcSDE for storing geometries. A table created using one of these field names will have the field name qualified in the table to avoid potential ambiguity. A qualified field name is returned as "USERNAME.TABLENAME.FIELDNAME" by Oracle and "DATABASE.USERNAME.TABLENAME.FIELDNAME" by SQL Server.

The following 14 field names will be qualified in ArcSDE: FID, AREA, LEN, POINTS, NUMOFPTS, ENTITY, EMINX, EMINY, EMAXX, EMAXY, EMINZ, EMAXZ, MIN_MEASURE and MAX_MEASURE.

The IField.Name property of these fields will be qualified when retrieved from the dataset�s fields collection. Attempting to retrieve the index of a qualified field using IClass.FindField or IFields.FindField requires the developer to qualify the field name; IFields2.FindFieldIgnoreQualification will find a field based on it�s "given" name, regardless of whether or not it�s qualified.
