用存储过程通过传入参数动态创建视图

CREATE OR REPLACE Procedure mytest(viewName Varchar2)
Is
V_i INTEGER;
v_sql VARCHAR2(200);
BEGIN
SELECT COUNT(*) INTO v_i
FROM sys.user_objects WHERE object_type= 'VIEW ' AND OBJECT_NAME= 'my_view ';
IF v_i =0 THEN
v_sql:= 'CREATE VIEW  ' ¦ ¦viewName ¦ ¦ ' as (select * from my_table) ';
EXECUTE IMMEDIATE v_sql;
END IF;
END;


执行：
execute mytest( 'v_abc ');


如果出现问题:
ORA-01031: 权限不足
ORA-06512: ÔÚ"MYTEST", line 10
ORA-06512: ÔÚline 1

解决如下：
用SYS登陆，显式的给该用户授权，不论你是否已经将DBA授权给该用户。

GRANT CREATE ANY VIEW TO THE_USER;

如果是建表，或者建触发一样：
GRANT CREATE ANY TABLE TO THE_USER;
GRANT CREATE ANY TRIGGER TO THE_USER;

然后运行，就OK了。
