query.where clause using variable for field name instead of hard coded

TracySchloss

I'm sure if it wasn't Friday afternoon, I'd figure this out on my own.

I am trying to set up a more generic function to construct and execute a query task. Instead of having my query.where clause be something like

selQuery.where = "DISTRICT= '" + myCode + "'";  //myCode coming from a FilteringSelect value

I'd like the field name to also be a variable. But I think the syntax for the where clause needs to be in the form of "FIELDNAME" = 'myValue', and I'm not quite sure how to get the quotes properly formatted in the string.

Please someone who's brain is still functioning, help me out!

Tracy,

Just make sure your field variable is a string. There where property is type string..

var myField = "DISTRICT"; . . . selQuery.where = myField + " = '" + myCode + "'"

I actually build the entire where statement in a string variable in most of my applications, then set .where to the variable.

Hope this helps and Happy Friday,
Chris B.

Glad you found it!

Sure enough, I had renamed my errorHandler function, but forgot to change the queryTask.on event listener

 queryTask.on('error', populateErrorHandler);

Thanks for the offer. I have a feeling it's something right in front of me, so I'm going to try a little longer. No sense in embarrassing myself.

If you would like to post your entire function, I'd gladly take a look at it.

Or if your application is publicly accessible I can look from there.

I tried that first, before I sent this and it wasn't working. I've changed several places in this function to use variables instead, maybe I should be expand to other lines. This might not be the problem at all!

Like I said - Friday - brain dead.
