mysql 外键创建表

Question

String query = "CREATE TABLE IF NOT EXISTS platforms ( " +
                   "id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, " +
                   "sites_id INTEGER UNSIGNED NOT NULL, " +
                   "baseline BLOB NULL, " +
                   "platform BLOB NULL, " +
                   "siteinfo BLOB NULL, " +
                   "databases BLOB NULL, " +
                   "PRIMARY KEY(id), " +
                   "INDEX (sites_id), " +
                   "FOREIGN KEY (sites_id) " +
                     "REFERENCES sites (id) " +
                        "ON DELETE NO ACTION " +
                        "ON UPDATE NO ACTION " +
                   ")ENGINE=InnoDB;";

这是我尝试创建的 MySQL 数据库的 SQL 查询。但是，我不知道为什么，我收到以下错误:

"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'databases BLOB NULL, PRIMARY KEY(id), INDEX (sites_id), FOREIGN KEY (sites_id) R' at line 1"

有人可以指出问题是什么吗？

DATABASES 是 reserved word 。使用反引号 ` 字符引用它:

`databases` BLOB NULL
