以下是请求:

 $this->getEntityManager()->createQueryBuilder()
            ->select("trace.action")
            ->addSelect("concat(user.nom, ' ', user.prenom)")
            ->from('MyBundle:Ttrace', 'trace')
            ->innerjoin('trace', 'MyBundle:User', 'user', 'user.id = trace.user')
            ->where('trace.datfin is null');

有人可以使用queryBuilder翻译吗?

谢谢 我尝试了这个,但它不起作用:

$this->getEntityManager()->createQueryBuilder()
            ->select("trace.action")
            ->addSelect("concat(user.nom, ' ', user.prenom)")
            ->from('MyBundle:Ttrace', 'trace')
            ->join('MyBundle:User', 'user')
            ->where('trace.datfin is null');

但它不起作用。

我也尝试过:

var margin = {top: 40, right: 20, bottom: 30, left: 40},
    width = 900,
    height = 700;

var x = d3.scale.ordinal()
    .rangeRoundBands([0, width], .1);

var y = d3.scale.linear()
    .range([height, 0]);

var xAxis = d3.svg.axis()
    .scale(x)
    .orient("bottom");

var yAxis = d3.svg.axis()
    .scale(y)
    .orient("left")
    .ticks(10)
    .tickFormat(d3.format("s"));

var tip = d3.tip()
  .attr('class', 'd3-tip')
  .offset([-10, 0])
  .html(function(d) {
    return "<strong>Popularity:</strong> <span style='color:teal'>" + d.popularity+"</span>";
  })

var svg = d3.select("#chart").append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
  .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");

svg.call(tip);

function updateChart( concert){

d3.tsv(concert+".tsv", type, function(error, data) {
  x.domain(data.map(function(d) { return d.month; }));
  y.domain([0, 45]);
  svg.append("g")
      .attr("class", "x axis")
      .attr("transform", "translate(0," + height + ")")
      .call(xAxis);

  svg.append("g")
      .attr("class", "y axis")
      .call(yAxis)
    .append("text")
      .attr("transform", "rotate(-90)")
      .attr("y", 6)
      .attr("dy", "1em")
      .style("text-anchor", "end")
      .text("Popularity");

  var pops= svg.selectAll(".bar")
      .data(data)
    .enter().append("rect")
      .attr("width", x)
      .attr("fill", function(d) {
        if (d.popularity> 30) {
           return "#010";
        else  
           return "000"; 
       })
      .attr("class", "bar")
      .attr("x", function(d) { return x(d.month); })
      .attr("width", x.rangeBand())
      .attr("y", height - 1)
      .attr("height", 1);

    pops.transition()
      .duration(1000)
      .delay(function (d, i) {
        return i * 100;
      })
      .attr("y", function(d) { return y(d.popularity); })
      .attr("height", function(d) { return height- y(d.popularity); });

    pops.on('mouseover', tip.show)
      .on('mouseout', tip.hide);

  });

}

function type(d) {
  d.popularity= +d.popularity;
  return d;
}

但是sql查询错误:      innerjoin用户on(trace.datfin为null)NONSENSE !!当然在sql查询中没有位置

那么,有人知道(他们很容易说)如何构建它(使用查询构建器)

TY

希望它会帮助某人:

$qb = $this->getEntityManager()->createQueryBuilder()
  ->select('trace.action')
  ->addSelect("concat(user.nom, ' ', user.prenom)")
  ->from('MyBundle:Ttrace', 'trace');
$qb->join('MyBundle:User', 'u', Join::WITH, $qb->expr()->eq('trace.user', 'u.id'));
$qb->where($qb->expr()->isNull('trace.datfin');
