用存储过程创建数据表:创建时注意必须添加authid current_user如果创建的表已存在存储过程继续执行但如不不加此关键语句存储过程将出现异常
这个语句相当于赋权限
例
创建语句如下
复制代码 代码如下:
create or replace
procedure sp_create_mnl(i_id varchar) authid current_user as
/*********************************
名称sp_create_mnl
功能描述创建模拟量历史数据存储表
修订记录
版本号 编辑时间 编辑人 修改描述
wylaok 创建此存储过程
wylaok 修改表名称及变量名称增加必要注释
入参出参描述
i_id 测点编号
**********************************/
v_tablename varchar();表名
v_flag number();
v_sqlfalg varchar();
begin
v_flag:=;
v_tablename:=CONCAT(MNL UPPER(i_id));
v_sqlfalg:=select count(*) from user_TABLES where table_name=||v_tablename||;
dbms_outputput_line(v_sqlfalg);
execute immediate v_sqlfalg into v_flag;
if v_flag= then 如果没有这个表 则去创建
begin
execute immediate create table ||v_tablename ||

createmnl(mnl_);
end;
