Answer 1

您可以尝试这样的事情：

$someDate = '2015-06-09';
$result = \DB::select(
    \DB::raw("SELECT count(*) as total FROM items WHERE DATE(w_laporan) = :someDate"),
    ['someDate' => $someDate]
);

Check Raw Expression

请尝试以下操作。

using System.Globalization; 

...

decimal myValue = -0.123m;
NumberFormatInfo percentageFormat = new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 };
string formattedValue = myValue.ToString("P2", percentageFormat); // "-12.30%" (in en-us)
