Feature Layer multiple definition expressions

EricBianchi1 — Sun, 10 Apr 2016 19:47:23 GMT

For example, if I have the code:

featureLayer.setDefinitionExpression("TYPE='BLUE'");

Can I set multiple expressions such as TYPE='RED' and TYPE='BLUE'?

If so, what is the proper syntax to do so?

Thanks!

Eric,

Sure it would be:

featureLayer.setDefinitionExpression("TYPE='BLUE' OR TYPE='RED'");

Eric,

AND is used when you want another field to have another value like "Type = 'RED' AND Lot = 'STUDENT'"

If you have many types, you can also use the syntax

featureLayer.setDefinitionExpression("TYPE in ('BLUE', 'RED')");
