Passing multiple values to setDefinitionExpression

[KennethRichards]

Is there a way to pass multiple values to the setDefinitionExpression method?

I tried this and it only reads the first value passed to it.

wellFeatureLayer.setDefinitionExpression("welltype='Gas'","welltype='Geothermal'","welltype='Water'" );

Could I pass some sort of array to it? Snippets of code would be greatly appreciated.

ah, the wonders of complex SQL expressions..

"FIELD_NAME = 'value 1' OR FIELD_NAME = 'value 2'"

If the definition expression is for one field, use IN operator then.
wellFeatureLayer.setDefinitionExpression("welltype IN ('Gas','Geothermal','Water')");
