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 replaceprocedure 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_output put_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 || ( DATETIME DATE MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AVG FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MIN FLOAT AGV FLOAT MAX FLOAT MINV FLOAT MAXV FLOAT AVGV FLOAT MAXTIME DATE MINTIME DATE ) tablespace WYG pctfree initrans maxtrans storage ( initial K next K minextents maxextents unlimited pctincrease ) ; execute immediate sqlstr; end; end if; end;
调用此存储过程复制代码 代码如下:
begin createmnl( mnl_ ); end;
例复制代码 代码如下:
