SQL EXCEPTION ORA-00911: invalid character

提示：

 

java.sql.SQLException: ORA-00911: invalid character

 

问题解决

 

String sql=

"SELECT p.name as name, count(e.id) as zhuanyeCount FROM employ e " +

"inner join professional p on e.zhuanye = p.id " +

"inner join glp_mt_relying_agency_history r on e.role_id = r.id" +str+

" group by p.name;";

 

SQL语句多了一个分号，在JDBC中多写一个分号，驱动将不可识别。

 

总结：

 

将异常提示在网上搜索也许会有意外的惊喜。
