MySQL-无法在列中插入NULL值,但是我指定了默认值吗?

mysql

我在MySQL中有一个表,其中有几列具有指定的默认值,但是当我尝试插入行时(未为这些默认列指定值),它抛出错误,提示我无法插入NULL值。

这是表格示例;

CREATE TABLE `users` (
  `Id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `UniqueName` varchar(120) NOT NULL,
  `Password` varchar(1000) NOT NULL,
  `PublicFlag` tinyint(1) NOT NULL,
  `NoTimesLoggedIn` int(10) unsigned NOT NULL DEFAULT '0',
  `DateTimeLastLogin` timestamp NOT NULL DEFAULT '1971-01-01 00:00:00',
  `UserStatusTypeId` int(10) unsigned NOT NULL,
  `Private` tinyint(1) NOT NULL DEFAULT '0',
  `SiteName` varchar(255) NOT NULL,
  `CountryId` int(10) NOT NULL DEFAULT '0',
  `TimeZoneId` varchar(255) NOT NULL DEFAULT 'UTC',
  `CultureInfoId` int(10) unsigned NOT NULL DEFAULT '0',
  `DateCreated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `UserCreated` int(10) unsigned NOT NULL,
  `LastUpdatedBy` int(10) unsigned NOT NULL,
  `DateLastUpdated` datetime DEFAULT NULL,
  PRIMARY KEY (`Id`),
  UNIQUE KEY `UniqueName_UNIQUE` (`UniqueName`),
  KEY `Index 3` (`SiteName`)
)

它抱怨TimeZoneId,当我填充TimeZoneId时,它抱怨CultureInforId。

我正在使用MySQL版本:5.1.43-community

这是我尝试插入的插入查询,是从NHibernate Profiler中获取的:

INSERT INTO Users
           (UniqueName,
            Password,
            PublicFlag,
            NoTimesLoggedIn,
            DateTimeLastLogin,
            SiteName,
            TimeZoneId,
            DateCreated,
            DateLastUpdated,
            Private,
            CountryId,
            CultureInfoId,
            UserCreated,
            LastUpdatedBy,
            UserStatusTypeId)
VALUES     ('zma@zm.com','u1uhbQviLp89P9b3EnuN/Prvo3A4KVSiUa0=',1,
0,'1/01/1971 12:00:00 AM','V9O1T80Q6D',NULL,'2/08/2010 2:13:44 AM',
'2/08/2010 2:13:44 AM',0, NULL, NULL, 4, 4,31)

改用DEFAULT关键字:

INSERT INTO users (TimeZoneId) VALUES (DEFAULT);
