10006: Layer's definition query uses unqualified field names for fields that exist in more than one table

Your map layer's definition query uses unqualified field names for fields that exist in more than one table. Ambiguous field names in more than one table of a join will give unknown results when used for draw and query operations.

Solution

• First, check the drawing performance of your basemap layer in ArcMap or your map service in the Preview window. See Working with basemap layers or Publishing map services for more information.
• If you see the need to make changes, provide a more qualified field name to identify the specific table to use.

More information

You can append the table name to the field name to provide a qualified name for the field you want to use.

Specify field names as TableName.FieldName.

This naming convention helps prevent duplicate field names when the target dataset and a join table have common field names.
