I need to run a query to get max value of field "IssueID", and then increment this value to add new feature to the layer.
var statisticDefinition = new esri.tasks.StatisticDefinition(); statisticDefinition.statisticType = "max"; statisticDefinition.onStatisticField = "IssueID"; statisticDefinition.outStatisticFieldName = "NewIssueID"; var query = new esri.tasks.Query(); query.outFields = ['*']; query.where = "1 = 1"; query.outStatistics = [statisticDefinition]; var queryTask = new esri.tasks.QueryTask(url); queryTask.execute(query,function(featureSet){
When initially , there are zero features in the layer, the query is getting error out.
