创建表时，UNIQUE KEY上的语法错误

问题描述：

我正尝试使用下面的代码在数据库中创建Tabe。但是，它不工作，我不明白为什么。创建表时，UNIQUE KEY上的语法错误

正在生成的错误是'UNIQUE KEY ID (ID)'上的语法错误，但根据我正在使用的教程（以及我可以找到的文档），看起来没问题。

我也试过'UNIQUE ID (ID)'和'UNIQUE ID'，但我仍然得到语法错误。

CREATE TABLE wp_offices (
    ID smallint(3) NOT NULL AUTO_INCREMENT, 
    office_created_by smallint(3) DEFAULT "0", 
    office_created_date datetime DEFAULT "0000-00-00 00:00:00" NOT NULL, 
    office_last_edited_by smallint(3) DEFAULT "0", 
    office_last_edited_date datetime DEFAULT "0000-00-00 00:00:00" NOT NULL, 
    office_name tinytext COLLATE latin1_general_ci, 
    address_1 tinytext COLLATE latin1_general_ci, 
    address_2 tinytext COLLATE latin1_general_ci, 
    town tinytext COLLATE latin1_general_ci, 
    county tinytext COLLATE latin1_general_ci, 
    postcode tinytext COLLATE latin1_general_ci, 
    telephone tinytext COLLATE latin1_general_ci, 
    fax tinytext COLLATE latin1_general_ci, 
    dx tinytext COLLATE latin1_general_ci, 
    email tinytext COLLATE latin1_general_ci, 
    google_maps text(256) COLLATE latin1_general_ci 
) 
UNIQUE KEY ID (ID);

有人能告诉我我做错了什么吗？谢谢。

答

它应该是在大括号

google_maps text(256) COLLATE latin1_general_ci, 
UNIQUE KEY ID (ID) 
);

啊，谢谢。我使用的教程在这种情况下是错误的，但很高兴这很简单！谢谢。 –

内创建表的代码将

CREATE TABLE wp_offices(
    ID SMALLINT(3) NOT NULL AUTO_INCREMENT , 
    office_created_by SMALLINT(3) DEFAULT "0", 
    office_created_date DATETIME DEFAULT "0000-00-00 00:00:00" NOT NULL , 
    office_last_edited_by SMALLINT(3) DEFAULT "0", 
    office_last_edited_date DATETIME DEFAULT "0000-00-00 00:00:00" NOT NULL , 
    office_name TINYTEXT COLLATE latin1_general_ci, 
    address_1 TINYTEXT COLLATE latin1_general_ci, 
    address_2 TINYTEXT COLLATE latin1_general_ci, 
    town TINYTEXT COLLATE latin1_general_ci, 
    county TINYTEXT COLLATE latin1_general_ci, 
    postcode TINYTEXT COLLATE latin1_general_ci, 
    telephone TINYTEXT COLLATE latin1_general_ci, 
    fax TINYTEXT COLLATE latin1_general_ci, 
    dx TINYTEXT COLLATE latin1_general_ci, 
    email TINYTEXT COLLATE latin1_general_ci, 
    google_maps TEXT(256) COLLATE latin1_general_ci, 
    UNIQUE KEY ID(ID) 
    );
