QueryTask where clause syntax, value from an array

TracySchloss — Sat, 11 Dec 2021 22:34:03 GMT

If I have an array of values, can't use these as input to a where clause? I am allowing the user to select multiple checkboxes, pushing the values into an array as they check. Then I want to be able to create a where clause for either a queryTask or a featureLayer.

I have an example of a where clause that looks like I can use IN, but I'm having a hard time getting the values from the array to be properly formatted. I am using a cbTree, which is a checkbox tree. The values from the checkboxes are getting populated into the array, I'm just not sure what to do with them next.

I got it to work. The syntax should be:

      function executeQuery(){
          searchList.sort();
          var sortedList = sortAndRemoveDuplicates(searchList);
          var sortedString = sortedList.join("','");
          var whereClause = "HOSP_TYPE IN ('" + sortedString + "')";
          console.log("whereClause = " + whereClause);
          searchQuery.where = whereClause;
          qTask.execute(searchQuery,queryHandler);
      }
