Query Task Question...

WesBailes — Sat, 21 Aug 2010 01:53:17 GMT

I'm working through some of the samples and am a little stumped with the query task sample. I found that in one of the tutorials that the querytask utilizes the displayfield for searching. Is there any way to query other fields in a specific layer? What about standalone tables? Thanks!

Wes,

The Query.text

Shorthand for a literal search text on the display field, equivalent to: where YourDisplayField like '%SearchText%'.

The Query.where is what you want to use if you want to specify a different kind of SQL query.

for querying stand alone tables you need to look at Feature Layer

The feature layer can be used to display features from one layer (or non-spatial table) of a Feature Service or a Map Service. If the underlaying layer (or table) is from a Feature Service , it can be used to edit features and apply those edits back to the server.

See documentation. http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/FeatureLayer.html

The QueryTask works with standalone tables too. (Internally the FeatureLayer uses the QueryTask.)
