Question

当我尝试这个Eloquent查询时，我得到0作为结果，当我期待217时：

OrderItem::whereBetween(
        'created_at',
        [
            DB::raw("CONVERT_TZ('$start_date 09:00:00', '+00:00', '-06:00')"),
            DB::raw("CONVERT_TZ('$end_date 18:00:00', '+00:00', '-06:00')")
        ]
    )->count();

如果我在上面做DB::getQueryLog()，请复制已编译的查询以使用MySQL Workbench在数据库上执行它，然后我得到217的预期结果。

select count(*) as aggregate 
from `order_items`
where
`created_at` between
CONVERT_TZ('2016-02-17 09:00:00', '+00:00', '-06:00') and
CONVERT_TZ('2016-02-29 18:00:00', '+00:00', '-06:00')

以下是该查询日志的var转储：

array (3) [
    'query' => string (82) "select count(*) as aggregate from `order_items` where `created_at` between ? and ?"
    'bindings' => array (2) [
        Illuminate\Database\Query\Expression (1) (
            protected value -> string (53) "CONVERT_TZ('2016-02-17 09:00:00', '+00:00', '-06:00')"
        )
        Illuminate\Database\Query\Expression (1) (
            protected value -> string (53) "CONVERT_TZ('2016-02-29 18:00:00', '+00:00', '-06:00')"
        )
    ]
    'time' => float 0.41
]

什么可能阻止Eloquent实施正常工作？

Answer 1

在您的查询中

select count(*) as aggregate from `order_items` where between CONVERT_TZ('2016-02-10 09:00:00', '+00:00', '-06:00') and CONVERT_TZ('2016-02-10 18:00:00', '+00:00', '-06:00');

我看到你使用$ date两次。因此，Laravel生成的SQL命令如下所示：

radius1

您将在查询中获得与复制sql命令时提到的日期不同的日期。

我没有看到任何不起作用

Answer 2

试试这个

whereRaw("`created_at` between
CONVERT_TZ('2016-02-17 09:00:00', '+00:00', '-06:00') and
CONVERT_TZ('2016-02-29 18:00:00', '+00:00', '-06:00')")

查询在PHP中不起作用，但直接在MySQL中起作用
