登陆数据库查看：

发现cursor_sharing被设置为smilar，修改为exact后错误消除

SQL> show parameter cursor

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
cursor_sharing                       string      SIMILAR

SQL> alter system set cursor_sharing=exact scope=both;

System altered.
