Question

此查询可以创建事件但不创建表格！

function updateGraph(nested, selectValue) {

  // Get the selected dataset
  var filtered = nested.filter( function(d) { return d.key == selectValue; });
    g.selectAll("#datapoints")
    .data(filtered[0].values)
    .enter().append("g")
    .each(function(d, i) { // So that multiple series can be included on the same graph
        var min = d3.min(d.values, function(d) { return d.value; } );
        var max = d3.max(d.values, function(d) { return d.value; } );

    // Join new data with old elements
        var points = d3.select(this).selectAll("circle")
          .data(d.values, function(d) { return (d.Plot); } );

    // Add new elements
        points.enter().append("circle")
          .attr("cy", y(d.key))
          .attr("r", 10)
          .style("opacity", 0.5)
          .style("fill", function(d) { return elevColor(d.Elevation); })
          .merge(points)
          .transition()
          .attr("cx", function(d) { return x((d.value-min)/(max-min)); });

    // Remove old elements not present in new data (doesn't do anything)
        points.exit().remove();
    });
}

任何想法？

您的活动安排程序是正确的。首先检查它的状态

SHOW VARIABLES LIKE 'event_scheduler'

默认情况下，事件计划程序状态已设置为DISABLED。要启用事件计划程序：

SET GLOBAL event_scheduler = ON;

表不是在事件mysql中创建的
