Question

我有两张桌子

<input type='number' min='.01' ng-model='threshold' />

我想要做的是根据日期将table2的所有新条目添加到table1中。我的想法是这样的

table1
+--------+-----+------+
|  DATE  |  VAR|   VAL|
+--------+-----+------+
|20160101|VAR_1|   0.4|
|20160101|VAR_2|   0.1|
|20160102|VAR_1|   0.6|
|20160102|VAR_2|   0.1|
|20160103|VAR_1|   0.5|
|20160103|VAR_2|   0.1|
+--------+-----+------+

table 2
+--------+-----+------+
|  DATE  |  VAR|   VAL|
+--------+-----+------+
|20160102|VAR_1|   0.6|
|20160102|VAR_2|   0.1|
|20160103|VAR_1|   0.5|
|20160103|VAR_2|   0.1|
|20160104|VAR_1|   0.3|
|20160104|VAR_2|   0.2|
|20160105|VAR_1|   0.2|
|20160105|VAR_2|   0.6|
|20160106|VAR_1|   0.3|
|20160106|VAR_2|   0.4|
+--------+-----+------+

但是我收到语法错误。使用NOT IN可以正常工作......

INSERT INTO table1 SELECT * FROM table2 WHERE date > (SELECT MAX(date) from table1);

非常感谢任何帮助！

这是尝试这种方式，我使用date1而不是date

var durationChartData = [];
var lineChartData = {
      labels: ["Jan","Feb", "Mar","Apr","May","Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
      datasets: [
          {
              label: "My Second dataset",
              fillColor: "rgba(124,181,236,0.4)",
              strokeColor: "rgba(124,181,236,1)",
              pointColor: "rgba(151,187,205,1)",
              pointStrokeColor: "#fff",
              pointHighlightFill: "#fff",
              pointHighlightStroke: "rgba(151,187,205,1)",
              data: [durationChartData[0],durationChartData[1],durationChartData[2],durationChartData[3],durationChartData[4],durationChartData[5],durationChartData[6],durationChartData[7],durationChartData[8],durationChartData[9],durationChartData[10],durationChartData[11]]
          }
      ]
    };
window.onload = function(){
    $.ajax({
        url: '/rest/analytical/home/viewed/line',
        type: 'GET',
        dataType: 'json',
        success: function (data) {
            dataLength = (data + '').length;
            for(var i=0; i<dataLength; i++){
            durationChartData[i] = data.ret[i].all;
            }
        },
        error: function (data) {
            console.log('duration Chart Data: ' + data);
        }
    });

    var linegraph = document.getElementById("linegraph");
    var bargraph = document.getElementById("bargraph"); 

    if(linegraph !== null){
        var ctx = linegraph.getContext("2d");
        window.myLine = new Chart(ctx).Line(lineChartData, {
            tooltipTemplate: "<%if (label){%><%=label%>: <%}%><%= value %> min",
            responsive: true
        });
    };

INSERT INTO基于第二个表的WHERE子句
