1.基本結構
create or replace procedure 儲存過程名字
(引數1 in number,
引數2 in number
) is
變數1 integer :=0;
變數2 date;
begin
54com.cn
end 儲存過程名字
2.select into statement
將select查詢的結果存入到變數中，可以同時將多個列儲存多個變數中，必須有一條
記錄，否則丟擲異常(如果沒有記錄丟擲no_data_found)
例子：
begin
select col1,col2 into 變數1,變數2 from typestruct where ***;
exception
when no_data_found then
***x;
end;
...3.if 判斷
if v_test=1 then
begin
do something
end;
end if;
4.while 迴圈
while v_test=1 loop
begin
***x
end;
end loop;
5.變數賦值
v_test := 123;
6.用for in 使用cursor
...is
cursor cur is select * from ***;
begin
for cur_result in cur loop
begin
v_sum :=cur_result.列名1+cur_result.列名2
end;
end loop;
end;
7.帶引數的cursor
cursor c_user(c_id number) is select name from user where typeid=c_id;
open c_user(變數值);
loop 54ne.com
fetch c_user into v_name;
exit fetch c_user%notfound;
do something
end loop;
close c_user;
/*************while迴圈*******************/
create or replace procedure stu_pro
asv_stu_name stu_info.stu_name%type;
v_stu_id stu_info.stu_id%type;
v_stu_addr stu_info.stu_addr%type;
v_count integer;
cursor stu_cur is select * from stu_info;
begin
if stu_cur%isopen then
dbms_output.put_line('stu_cur已經被人開啟了。。。');
close stu_cur;
end if;
open stu_cur;
--先fetch下
fetch stu_cur into v_stu_id,v_stu_name,v_stu_addr;
while stu_cur%found loop
if v_stu_addr='sss' then
dbms_output.put_line('------------');
update stu_info set stu_addr = 'zhang';
end if;
--迴圈中往下fetch
fetch stu_cur into v_stu_id,v_stu_name,v_stu_addr;
end loop;
commit;
close stu_cur;
end;
/******%rowcount屬性可以知道行數**********/
/**********cursor fo 迴圈*****for in *****不能顯示開啟和提取和關閉資料*********************/
/*******不帶引數的不能加括號********/
create or replace procedure stu_list
--定義異常
nonumber exception
ascursor stu_cursor is select * from stu_info;
begin
for stu_record in stu_cursor loop
dbms_output.put_line(stu_record.stu_name||'住在'||stu_record.stu_addr);
if(stu_record.stu_addr='')
end loop;
exception
when nonumber then
dbms_output.put_line('沒有數目');
--no_data_found是oracl自己內部定義的異常
when no_data_found then
dbms_output.put_line('no found record');
end;
