MYSQL JDBC CachedRowSetImpl 临时表错误

问题：
In a stored procedure, if a result set is selected from a temporary table and then

deleted, a MySQLSyntaxErrorException occurs from the driver trying to perform SHOW FULL
COLUMNS on the non-existent temporary table.

解决方法：在mysql URL  里加入:
"useDynamicCharsetInfo=false"

Jboss deploy/mysql-ds.xml里加入如下语句:

   <connection-url>jdbc:mysql://localhost:3306/mrp?useUnicode=TRUE</connection-url>
   <connection-property name="characterEncoding">utf8</connection-property>
<connection-property name="useDynamicCharsetInfo">false</connection-property>
