我得到了这个回复给我:
{
"GROUP_CONCAT(DISTINCT(CONCAT(\"MAX(IF(pa.printer = \"\"\", printer, \"\"\", pa.printer, NULL)) AS \", printer)))":
"MAX(IF(pa.printer = \"JP4-3\", pa.printer, NULL)) AS JP4-3,MAX(IF(pa.printer = \"JP4-1\", pa.printer, NULL)) AS JP4-1,MAX(IF(pa.printer = \"JP4-2\", pa.printer, NULL)) AS JP4-2,MAX(IF(pa.printer = \"B3\", pa.printer, NULL)) AS B3,MAX(IF(pa.printer = \"A2\", pa.printer, NULL)) AS A2"
}
我想得到这个的值,但只是字符串。我无法摆脱{}。这应该是如此简单,但无法在任何地方找到答案。
以下只是我要做的事情
主要目标是MySQL数据透视表。接听2个电话,但我很好。
$listQuery = PrintJob::select(DB::raw('GROUP_CONCAT(DISTINCT(CONCAT("MAX(IF(pa.printer = """, printer, """, pa.printer, NULL)) AS ", printer)))'))->get();
这将返回上面的结果:
$json = $listQuery[0];
然后在此查询中使用它
$data = PrintJob::select(DB::raw('DATE(calendar.datefield) as date'), DB::raw('SUM(print_jobs.quantity) as sum'), DB::raw($listQuery))
->leftJoin('mo_numbers', 'mo_numbers.mo_id', '=', 'print_jobs.mo_id')
->rightJoin('calendar', 'calendar.datefield', '=', 'print_jobs.job_date')
->whereDate('calendar.datefield', '>=', date($from))
->whereDate('calendar.datefield', '<=', date($to))
->groupBy('date')
->toSql();
//->get();
答案 0 :(得分:1)
这是一些奇怪的东西,但是这将获得价值:
$value = current(json_decode($json, true));
获取密钥:
$key = key(json_decode($json, true));
或者一举一动:
list($key, $val) = each(json_decode($json, true));
