How to query for Features in a Domain string attribute field

PHerk

 For my customer I am building an application where I query a Featurelayer.

function queryFeatureLayer() {
var query = {
spatialRelationship: "intersects",
outFields: ["*"],
returnGeometry: true,
where: field = value
};
featurelayer.queryFeatures(query).then(function(result) {
// handle results
});
}

This works for a simple attribute field (string) .

Assume field = "animal", value = "dog"

where: "animal" = "dog"

This returns all features that have the string "dog" in this field.

Now the "animal" field is changed to hold a  string-list, a domain. In AGOL this gives a popup list with a few animals Assume: ("dog", "cat", "mouse").

I want to query this field but I get errors using:

where: "animal = dog"

or

where: "animal = 1"

The error:

Cannot perform query. Invalid query parameters.

How can I set up a working query to search for all Features that have "dog" set in field "animal" using a Domain string attribute field?

Thanks

No, but the single ' solved it.

I was misled because I got results without the single quotes on an Attribute Field without a domain list attached.

For others with the same issue:

where: "animal = dog" works on an Attribute Field which is just a string.

where: "animal = dog" fails on an Attribute Field which has a Domain list attached.

 

solution:

Always use: "animal = 'dog'"

Thank you Robert. Appreciated!
