第一次写存储过程
学编程,好像都有个仪式,打印hello Word,我学python打印了,好简单print(‘hello Word’),plsql里要复杂一点,点开存储过程编辑框,输入:create or replace procedure hello is
begin
dbms_output.put_line('hello word');
end hello;
然后进命令窗口,SQL> set serverout on;
SQL> exec hello;
hello word
PL/SQL procedure successfully completed
成功打印出来。现在想写个稍微复杂一点的,自己建个表sb,只有一个字段gbidsb,现在想手输入商品代码,执行过程从另一个数据库取数,插入sb表中。过程如下:
create or replace procedure getgdid( n_number in number) is
n_num number;
begin
select gbid into n_num from goodsbase@hdqt_db t where t.gbid=n_number;
dbms_output.put_line('代码'||n_num);
insert into sb(gbidsb) values (n_num);
commit;
end getgdid;
然后在命令窗口执行:
SQL> exec getgdid(754985);
代码754985
PL/SQL procedure successfully completed
完成,用select * from sb 查询有结果,成功。
