definitionExpression property
The sublayer's definition expression.
The definition expression string uses the SQL-92 where clause syntax (https://en.wikipedia.org/wiki/SQL-92). Be sure to escape special characters in the expression string as required for your platform. The DATE keyword expects the date format yyyy-mm-dd and the TIMESTAMP keyword expects the time stamp format yyyy-mm-dd hh:mm:ss. For more information, see the ArcGIS Blog article Querying Feature Services Date-Time Queries.
