SQL EXCEPTION ORA-00911: invalid character

提示：

 

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

 

問題解決

 

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語句多了一個分號，在JDBC中多寫一個分號，驅動將不可識別。

 

總結：

 

將異常提示在網上搜索也許會有意外的驚喜。
