first_name
列中有一个错误的空格。由于此错误,user_account
表无法创建。稍后,由于所引用的表不存在,无法创建引用user_account
的外键。
@Autowired
@Column(name = "first _name")
// ------------------^^^^
// Remove the space!
private String FirstName;
错误消息指向在last_name
之前出现的_name
,因此可以从这里开始查找问题。MySQL通常对语法错误的确切字符位置有很好的描述性:
您的SQL语法中有一个错误;请查看与您的MySQL服务器版本相对应的手册,查找在'_name varchar(255),l附近使用的正确语法
问题内容: 当我执行以下两个查询时(我将它们简化为绝对必要): 我收到以下错误:错误1005(HY000):无法创建表’./test/bar.frm’(errno:150) 我的错误在哪里?半个小时盯着我看,我还没找到他。 问题答案: 来自约束 如果重新创建已删除的表,则该表必须具有符合引用该表的外键约束的定义。如前所述,它必须具有正确的列名和类型,并且必须在引用的键上具有索引。如果不满足这些条件
我正在尝试迁移Rails MySQL数据库,出现以下错误: ActiveRecord::声明无效:MySQL2::Error:不能创建表.(errno: 150"外键约束格式不正确"): CREATE TABLE(intAUTO_INCREMENTPRIMary关键,varchar(255),int,int,datetime非空,datetime非空,INDEX(),INDEX(),CONSTRA
问题内容: 我正在用MySQL Workbench做一个小型数据库。我有一个名为“ Immobili”的主表,它具有由四列组成的主键:(Comune,Via,Civico,Immobile)。 现在,我还有其他三个表,它们具有相同的主键(Comune,Via,Civico,Immobile),但是这些字段也引用了表Immobili。 第一个问题:我可以同时创建主键还是外键吗? 第二个问题:当我尝试
我有两张桌子。第一个是人口;第二个是空的。 我希望第二个有一个外键,它引用第一个中的一列。 null 架构: 填充。为空。 不能成为的外键: MySQL没有提供错误的原因;不返回: 我拥有所需的数据库权限。 我已经仔细检查了列(甚至表)是否具有相同的排序规则(字符集不适用于INT列): MySQL无法添加外键约束 MySQL:错误1215(HY000):无法添加外键约束 无法添加外键约束-MySQ
表a已成功创建... 错误1215(HY000):无法添加外键约束 无法创建表b
问题内容: 我正在尝试通过使用外键来确保表之间的数据一致性,以便DBMS可以检查错误。但是,由于某些原因,我们似乎无法做到这一点。有什么错误,还有替代方法吗?另外,当我填写具有外键的表时,无法填写为外键保留的字段,对吗?另外,外键是否完全视为键? 问题答案: 最可能的问题是此行: classLeader的数据类型为VARCHAR(255)。这有 匹配数据类型 的引用的列… 。当然,表必须存在,列也
