我的表数据有两个条件price_id =2
和price_id = 1
,数据如下所示。
所以我的条件是weekday_am
列值为null
或empty
或0.00
price_id =2
我需要在{{1}处取值并且相同的逻辑将适用于列price_id = 1
,weekday_pm
,weekend_am
。所以我正在做的是我用两个不同的条件写了两个查询,并使用foreach循环检查值。但它给出了错误的结果。
查询代码:
weekend_pm
对于上述查询,我发现错误,因为值没有改变它只取$ArrayTier = BundlePrice::where('bundle_id',$id)->where('price_id','=','2')->get();
$ArrayDefault = BundlePrice::where('bundle_id',$id)->where('price_id','=','1')->get();
foreach($ArrayTier as $value)
{
$bundle_id = $value->bundle_id;
$asset_id = $value->asset_id;
foreach($ArrayDefault as $v)
{
if(!empty($value->weekday_am) || ($value->weekday_am != null))
{
$weekam = $value->weekday_am;
}else{
$weekam = $v->weekday_am;
}
if(!empty($value->weekday_pm) || ($value->weekday_pm != null))
{
$weekpm = $value->weekday_pm;
}else{
$weekpm = $v->weekday_pm;
}
if(!empty($value->weekend_am) || ($value->weekend_am != null))
{
$nonweekam = $value->weekend_am;
}else{
$nonweekam = $v->weekend_am;
}
if(!empty($value->weekend_pm) || ($value->weekend_pm != null))
{
$nonweekpm = $value->weekend_pm;
}else{
$nonweekpm = $v->weekend_pm;
}
}
$primaryArray[] = ['asset_id' => $asset_id,'weekam' => $weekam,'weekpm' => $weekpm,'nonweekam' => $nonweekam,'nonweekpm' => $nonweekpm];
}
的最后一行值
以上代码的结果是:
price_id =1
如果您看到上述内容,则会为少数几个地方重复相同的值。 但期待结果应如下所示:
array:3 [▼
0 => array:5 [▼
"asset_id" => 2
"weekam" => 150.0
"weekpm" => 320.0
"nonweekam" => 160.0
"nonweekpm" => 420.0
]
1 => array:5 [▼
"asset_id" => 1
"weekam" => 120.0
"weekpm" => 180.0
"nonweekam" => 220.0
"nonweekpm" => 420.0
]
2 => array:5 [▼
"asset_id" => 4
"weekam" => 120.0
"weekpm" => 320.0
"nonweekam" => 220.0
"nonweekpm" => 420.0
]
]
有人可以帮我解决这个问题吗?或者请建议我任何mysql查询,可以在单个查询中执行此操作,而不是通过foreach循环。谢谢
答案 0 :(得分:2)
您已经忘记加入资产ID,因此在循环播放时您会感到胡言乱语。这样做:
$prices = BundlePrice::where('bundle_id',$id)->get()->groupBy("asset_id"); //The group by is done on the collection, not the query: https://laravel.com/docs/5.4/collections#method-groupby
foreach($prices as $bundleprice) {
$price = collect($bundleprice)->where("price_id",1)->first();
$default = collect($bundleprice)->where("price_id",2)->first();
if (empty($price) && empty($default)) { continue; }
if (empty($default)) {
$default = $price;
}
$weekam = !empty($price->weekday_am)?$price->weekday_am:$default->weekday_am;
$weekpm = !empty($price->weekday_pm)?$price->weekday_pm:$default->weekday_pm;
$nonweekam = !empty($price->weekend_am)?$price->weekend_am:$default->weekend_am;
$nonweekpm = !empty($price->weekend_pm)?$price->weekend_pm:$default->weekend_pm;
$primaryArray[] = ['asset_id' => $default->asset_id,'weekam' => $weekam,'weekpm' => $weekpm,'nonweekam' => $nonweekam,'nonweekpm' => $nonweekpm];
}
看起来也更清洁。
