我有一个列名为firmware\u flash\u result的表,它不是fail就是pass。查询生成器为pass返回正确的结果,但为failure返回错误的结果。
实际查询及结果:
SELECT COUNT(DISTINCT `payment_module_id`)
FROM `payment_prod_pograms`
WHERE `created_at` >= "2018-09-17 00:00:00" AND
(
`payment_module_id` LIKE "PB10____18____" OR
`payment_module_id` LIKE "PM10____18____"
) AND
CHAR_LENGTH(`payment_module_id`) = 14 AND
`firmware_flash_result` = "FAIL";
+-------------------------------------+
| COUNT(DISTINCT `payment_module_id`) |
+-------------------------------------+
| 0 |
+-------------------------------------+
laravel查询生成器:
$payment_prod_failed_test = DB::table('payment_prod_pograms')
->where('created_at','>=','2018-09-17 00:00:00')
->whereRaw('char_length(payment_module_id) = 14')
->where('payment_module_id','like','%PB10____18____%')
->orWhere('payment_module_id','like','%PM10____18____%')
->where('firmware_flash_result','=','FAIL')
->distinct()
->count('payment_module_id');
上面的查询返回的结果是453,这是不可能的。
经过一番调试,我发现:
->orWhere('payment_module_id','like','%PM10____18____%')
导致这个错误的原因是什么?
数据库中有1515个条目,所有条目都通过了,但此查询返回的结果不同。。我做错什么了?任何帮助都将不胜感激

您正在将您的where payment\u模块\u id分组为%pb10\uuuuuuuuuuuuuuuuuuuuuuuuuuuuu%或%pm10\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。这是通过使用闭包来完成的。
