Thread: Query Component

  1. #1

    Default Query Component

    I've a queryComponent which executes a sql query and I'm trying to pass it to an xactionComponent:

    MetaLayerHome2 = {
    executeQueryComponentDefinition: {
    var executeQueryComponent = 
        name: "executeQueryComponent",
        type: "queryComponent",
        htmlObject: "queryObject",
        executeAtStart: true,
        queryDefinition: MetaLayerHome2.executeQueryComponentDefinition,
        result: "query_result",
        postExecution: function(){
            $('#queryObject').html("" + this.result);
    sample = 
      name: "sample",
      type: "xaction",
      solution: "cdf-samples",
      path: folder01,
      action: "QueryResult.xaction",
      parameters: [["query_result","query_result"]],
      htmlObject: "sampleObject",
      executeAtStart: true,
    How is the query stored in "query_result"?
    I've debugged it and seems to be an array of arrays [["name1", "value1"], ["name2", "value2"], ["name3", "value3"]]...but I don't know what I'm doing wrong.
    Can it be passed to the xaction?

    Here's something you can try. First remove the line result: "query_result" from your executeQueryComponent definition. I was doing the same thing and I was told that result is not a value you assign, result is where the actual results are stored. So remove that line from you definition. Declare query_result as a global variable. Then in the post execution function of executeQueryComponent assign result to query_result -> query_result = this.result;

    I think that would work, but maybe someone on here with more knowledge can give a better solution.

    Also remove from the post Execute function the line for setting the #queryObject.html.

    Thanks, now It works properly.
    I've the query listening to a select component.To make it work correctly I've had to put:
    postExecution: function(){Dashboards.fireChange('query_result',this.result)}
