【问题描述】：
谁能解释我为什么会收到这个错误（下面是完整的堆栈跟踪）：
原因：org.apache.openjpa.lib.jdbc.ReportingSQLException：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 1 行的 'TYPE = innodb' 附近使用正确的语法** {stmnt 763763032 CREATE TABLE ADMIN_USER (admin_id BIGINT NOT NULL AUTO_INCREMENT, first_name VARCHAR(255), last_name VARCHAR(255) ), user_name VARCHAR(255), PRIMARY KEY (admin_id)) TYPE = innodb} [code=1064, state=42000]*
我有一个带有 MySQL 5.5.11 和 openJPA 1.2.2 和 Geronimo 2.2.1 with Tomcat 6 的网络应用程序。我可以很好地解散.ear。但是当我提交我的表单以保留 Admin @Entity 时，我收到上面的以下错误。
另外，我使用tranql-connector-mysql-local-1.5.rar（来自 Geronimo 存储库）作为我的连接器。

【问题讨论】：
-
当我手动创建表时，我可以按预期插入我的管理员@Entity。但我仍然不知道为什么 openJPA 不会创建我的表。假设将 openjpa.jdbc.SychronizedMappings 属性设置为“buildSchema”的值来创建我的表？
-
您确定您实际连接的是 MySQL 而不是 Derby DB？
-
如果我能够使用我的网络应用程序插入 MySQL 中的表。所以我会说我正在连接到 MySQL。似乎我的问题是我无法根据我的实体创建表。
-
您是否尝试过使用异常中显示的 SQL？ CREATE TABLE ADMIN_USER (admin_id BIGINT NOT NULL AUTO_INCREMENT, first_name VARCHAR(255), last_name VARCHAR(255), user_name VARCHAR(255), PRIMARY KEY (admin_id)) TYPE = innodb
-
如果我删除 'TYPE = innodb'，异常中的 SQL 将起作用。如果我在命令中保留 'TYPE = innodb'，则会收到以下错误：错误代码：1064 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 1 行的“TYPE”附近使用正确的语法。此外，我必须使用模式名称完全限定表。除此之外，异常中的确切 SQL 有效。
