事务回滚出错

不会游泳的鱼

我之前问了关于一晚上不登录系统，第二天登录的时候会出现事务回滚出错，应该是mysql数据库特有的，根据贴子里如下方法修正后，tomcat启动不起来了，提示没有sysdate字段？
修正方法：

在长时间没有访问tomcat后，数据库连接已经失效，连接池因为没有检测，所以认为连接有效，导致连接出错。避免这种错误的方法是设置连接有效查询sql语句。设置后，连接池会使用该sql语句测试连接是否有效，如果无效，会重新建立连接。
设置方法为：在server.xml中的<Resource>节点中增加属性validationQuery="select   sysdate  from  dual;"。例如：
<Resource name="system" auth="Container" type="javax.sql.DataSource" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://127.0.0.1:1433/x5_1900"
username="sa" password="sa" maxActive="10" maxIdle="5"
validationQuery="select  sysdate  from  dual;"/>



修正后启动tomcat报错：

yinlun

select   sysdate  from  dual这句话是在连oracle时用的，mysql里你可以用
select current_date或者select current_time;
ms sql 可以用select getdate()
