Oracle- 存儲過程和異常捕捉

時間 2019-11-20

原文原文鏈接

　　這段時間晚上有時候去打打球，回家看看電視劇，日子一每天過……。學了點ORACLE存儲過程基礎，做一下備註，以便往後需查閱。java

建立無參存儲過程sql

create procedure p_myPro1 is
begin
  insert into dept(deptno,dname,loc) values(60,'ccx','321321');
end;

修改無參存儲過程oracle

create or replace procedure p_myPro1 is
begin
  insert into dept(deptno,dname,loc) values(60,'ccx','321321'); 
end;

建立和修改有參存儲過程ide

create or replace procedure p_myPro2(spName varchar2,newSal number) is
begin
    update emp set sal=newSal where ename=spName;
end;


call p_myPro2('SCOTT','1111');

建立和修改有參存儲過程帶反回值工具

create or replace function f_myPro3(spName varchar2)
return number is
yearSal number(7,2);
begin
  select sal*12 into yearSal from emp where ename=spName;
  return yearSal;
end;

調用方法：select f_mypro3('SCOTT') from dual;spa

查看錯誤信息
show error;code

調用存儲過程
調用存儲過程的方式有兩種，call,execserver

exec是sqlplus的命令，只能在sqlplus中使用。和 set serveroutput on 一塊兒用。call是sql命令，任何工具均可以使用。對象

例如：call p_myPro1() blog

Oracle輸出語句過程

dbms_output是oracle所提供的包(相似java的開發包)，該包包含一些過程，put_line就是dbms_output包的一個過程。

Oracle變量的使用例子

declare
v_ename varchar2(5);
v_sal number(7,2);
begin
  select ename,sal into v_ename,v_sal from emp where empno=7369;
  dbms_output.put_line('姓名'||v_ename||'   工資'||v_sal);
end;

Oracle異常捕捉

declare
v_ename varchar2(5);
v_sal number(7,2);
begin
  select ename,sal into v_ename,v_sal from emp where empno=1111;
  dbms_output.put_line('姓名'||v_ename||'   工資'||v_sal);
  
  exception
  when no_data_found then
    dbms_output.put_line('SELECT INTO沒有找到數據');
  when not_logged_on then
    dbms_output.put_line('沒有鏈接到ORACLE');
  
end;

錯誤號	異常錯誤信息名稱	說明
ORA-0001	Dup_val_on_index	違反了惟一性限制
ORA-0051	Timeout-on-resource	在等待資源時發生超時
ORA-0061	Transaction-backed-out	因爲發生死鎖事務被撤消
ORA-1001	Invalid-CURSOR	試圖使用一個無效的遊標
ORA-1012	Not-logged-on	沒有鏈接到ORACLE
ORA-1017	Login-denied	無效的用戶名/口令
ORA-1403	No_data_found	SELECT INTO沒有找到數據
ORA-1422	Too_many_rows	SELECT INTO 返回多行
ORA-1476	Zero-divide	試圖被零除
ORA-1722	Invalid-NUMBER	轉換一個數字失敗
ORA-6500	Storage-error	內存不夠引起的內部錯誤
ORA-6501	Program-error	內部錯誤
ORA-6502	Value-error	轉換或截斷錯誤
ORA-6504	Rowtype-mismatch	宿主遊標變量與 PL/SQL變量有不兼容行類型
ORA-6511	CURSOR-already-OPEN	試圖打開一個已處於打開狀態的遊標
ORA-6530	Access-INTO-null	試圖爲null 對象的屬性賦值
ORA-6531	Collection-is-null	試圖將Exists 之外的集合( collection)方法應用於一個null pl/sql 表上或varray上
ORA-6532	Subscript-outside-limit	對嵌套或varray索引得引用超出聲明範圍之外
ORA-6533	Subscript-beyond-count	對嵌套或varray 索引得引用大於集合中元素的個數.

對這種異常狀況的處理，只需在PL/SQL塊的異常處理部分，直接引用相應的異常狀況名，並對其完成相應的異常錯誤處理便可。
