Question

我试图将此MySQL转换为MS SQL Server，但出现以下错误

第102层15级州立69行     “ PENDING”附近的语法不正确。

我从MySQL的字段名称中删除了所有的'`'，并且还更改了Unsigned。

DROP TABLE IF EXISTS `appointments`; CREATE TABLE `appointments` ( `appointment_id` int(10) UNSIGNED NOT NULL, `clinic_id` int(10) UNSIGNED DEFAULT NULL, `user_id` int(10) UNSIGNED NOT NULL, `patient_name` varchar(255) DEFAULT NULL, `patient_phone` varchar(20) DEFAULT NULL, `appointment_date` date NOT NULL, `appointment_time` time DEFAULT '00:00:00', `appointment_status` enum('PENDING','ACCEPTED','DECLINED','VISITED') NOT NULL DEFAULT 'PENDING', `is_rescheduled` tinyint(1) DEFAULT '0', `is_cancelled` tinyint(1) DEFAULT '0', `cancel_reason` varchar(255) DEFAULT NULL, `amount` decimal(10,2) DEFAULT NULL, `fee` decimal(10,2) DEFAULT NULL, `is_paid` tinyint(1) DEFAULT '0', `causer_id` int(11) DEFAULT NULL, `causer_type` varchar(255) DEFAULT NULL, `availability_id` int(10) UNSIGNED NOT NULL, `advice` varchar(500) DEFAULT '''''', `diagnosis` varchar(500) DEFAULT '''''', `appointment_created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP, `appointment_updated_at` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP, `deleted_at` timestamp NULL DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

进入

  [Appointment_Id] int CHECK ([Appointment_id] > 0) NOT NULL,

) ;

Answer 1

枚举似乎在SQL SERVER中不可用，请尝试CHECK

[Appointment_Status] varchar(10) NOT NULL 
       CHECK (Appointment_Status IN('PENDING','ACCEPTED','DECLINED','VISITED'))  DEFAULT 'PENDING',
