ksql的语法

qibuzou

关键字必须大写，字段必须带别名？

qibuzou

  var options = {};
         var param = new  biz.Request.ActionParam();
         
        param.setString("htbh","123");
        var process = "/WCPRCSystem/_05_ZLGL/process/xmhfxx/xmhfxxProcess";
        var activity = "mainActivity";
        options.contentType = 'application/json';
        options.process = process;
        options.activity = activity;
        options.dataType = "json";
        options.parameters = param;
        options.action = "getMaxHfBianMa";
        options.callback = function(data){
                if(data.state){
                        //成功
                        alert("调用成功");
                }else{
                        //失败
                        biz.Request.errorMessage(data, "执行失败！", null, null);
                }                       
        };
       
   var  mainData = biz.Request.sendBizRequest(options);
  我这样接受收据对不对，正确的方式是怎么做的

qibuzou

上面 的问题我知道了，列名的别名前必须有as关键字。
请帮我解答下4楼的问题

qibuzou

var options = {};
         var param = new  biz.Request.ActionParam();
         
        param.setString("htbh","123");
        var process = "/WCPRCSystem/_05_ZLGL/process/xmhfxx/xmhfxxProcess";
        var activity = "mainActivity";
        options.contentType = 'application/json';
        options.process = process;
        options.activity = activity;
        options.dataType = "json";
        options.parameters = param;
        options.action = "getMaxHfBianMa";
        options.callback = function(data){
                if(data.state){
                        //成功
                        alert("调用成功");
                }else{
                        //失败
                        biz.Request.errorMessage(data, "执行失败！", null, null);
                }                        
        };
        
   var result = biz.Request.sendBizRequest(options);
已经调用成功，我想知道的是我怎么才能拿到action里来的数据，datatype='json',应该是json方式获取？请写具体点，谢谢

qibuzou

另外我取出的数据并不想跟bizdata组件建立联系，就是在js中做判断之用，请帮忙写个调用的例子，如action里获得的是col1,col2,col3的三列共10行数据，我怎么取其中的第i行第j列的值。困扰很久了。求解答

qibuzou

等不到回答，自己都解决了
