Question

我有一个查询我想运行以创建表用户，但在执行查询时出现此错误：Started executing query at Line 1 Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '＆＃39;。总执行时间：00：00：00.031`

这是我的查询：

    CREATE TABLE `users` (
  `id` int(8) unsigned NOT NULL AUTO_INCREMENT,
  `login` varchar(30) NOT NULL,
  `password` varchar(32) NOT NULL,
  `secret` varchar(16) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `login` (`login`)
);

有人能让我知道为什么在运行我的查询时出现此错误？

Answer 1

您正在尝试在SQL服务器上运行MySQL语法。

这是重写的SQL-Server语法。

SQL-server不支持反引号（'）所以我删除了它们。
SQL-server不支持AUTO_INCREMENT，而SQL-server正在使用IDENTITY。
SQL服务器不支持unsigned，所以我删除了它。
SQL-server不支持int（8）所以我只将它改为int。

CREATE TABLE users (
    id int NOT NULL IDENTITY(1,1),
    login varchar(30) NOT NULL,
    password varchar(32) NOT NULL,
    secret varchar(16) NOT NULL,   
    CONSTRAINT PK_ID PRIMARY KEY (id),
    CONSTRAINT UK_login UNIQUE (login)
);

修改

命名索引。

我认为您尝试在MySql中使用Sql Sever语法，Sql server因使用（`）字符而引发错误。

使用此示例中的syntax：

<强> MySQL的：

CREATE TABLE Persons (
    ID int NOT NULL AUTO_INCREMENT,
    LastName varchar(255) NOT NULL,
    FirstName varchar(255),
    Age int,
    UNIQUE (ID),
    PRIMARY KEY (ID)
);

SQL Server：

CREATE TABLE Persons (
    ID int NOT NULL IDENTITY(1,1),
    LastName varchar(255) NOT NULL,
    FirstName varchar(255),
    Age int,
    CONSTRAINT PK_Person_ID PRIMARY KEY (ID),
    CONSTRAINT UC_Person_LastName UNIQUE (LastName)
);

语法错误执行Create Table
