我有一个问题,当我尝试使用 maatwebsite/laravel-excel 到.csv从数据库生成数据时,出现如下错误:stdClass类的对象无法转换为字符串。
有时,当我仅使用一个字段从数据库中选择数据时,该文件可以生成(.csv)。这是我的错误:
at HandleExceptions->handleError(4096, 'Object of class stdClass could not be converted to string', '/vendor/phpoffice/phpexcel/Classes/PHPExcel/Cell/DefaultValueBinder.php', 65, array('cell' => object(PHPExcel_Cell), 'value' => object(stdClass)))
这是我从数据库中获取数据的查询,var $ temp用于容纳查询结果。
public function coba ($type){
$temp = DB::select(DB::raw("select regionalid,
nvl(sum(case when lastactiontype='0' then totalcharge end),0) as creditlimit_usage,
count(case when lastactiontype='0' then msisdn end) as creditlimit_rec,
nvl(sum(case when lastactiontype='1' then totalcharge end),0) as blocked_usage,
count(case when lastactiontype='1' then msisdn end) as blocked_rec,
nvl(sum(case when lastactiontype='2' then totalcharge end),0) as adjusted_usage,
count(case when lastactiontype='2' then msisdn end) as adjusted_rec,
nvl(sum(case when lastactiontype='3' then totalcharge end),0) as sms_usage,
count(case when lastactiontype='3' then msisdn end) as sms_rec,
nvl(sum(case when lastactiontype='5' then totalcharge end),0) as call_usage,
count(case when lastactiontype='5' then msisdn end) as call_rec,
nvl(sum(case when lastactiontype in ('1','2','3','5') then totalcharge end),0) as total_usage,
count(case when lastactiontype in ('1','2','3','5') then msisdn end) as total_rec
from alarms_v2
where alarmdate = '$today'
group by regionalid order by regionalid"));
return Excel::create('datadoc', function ($excel) use ($temp) {
$excel->sheet('mySheet', function ($sheet) use ($temp) {
$sheet->fromArray($temp);
});
})->download($type);
我希望能够从数据库生成数据到.csv或excel,它可以正常工作。
最佳答案
尝试这个:
$sheet->fromArray((array)$temp);
