Oracle 查看 表, 存储过程, 触发器, 函数, 等对象定义语句
有时候,我们想查看表,存储,触发器等对象的定语语句,有以下两种方法:
1. 查 all_source 表
2. 用 DBMS_METADATA 包。
一. 通过 all_source 表
先来确认下,通过all_source 表可以查看哪些类型的对象:
SQL> SELECT distinct type FROM ALL_SOURCE;
TYPE
------------
PROCEDURE
PACKAGE
PACKAGE BODY
LIBRARY
TYPE BODY
TRIGGER
FUNCTION
JAVA SOURCE
TYPE
从以上的结果我们可以看到,我们可以通过该表查询的对象.
查看存储过程定义语句:
SQL> SELECT text FROM ALL_SOURCE where TYPE='PROCEDURE' AND NAME ='ADDCUSTBUSS';
TEXT
--------------------------------------------------------------------------------
PROCEDURE addcustbuss (
acustid IN custbuss.custid%TYPE,
bussname IN custbuss.businessname%TYPE,
aopid IN custbuss.opid%TYPE,
acreatetime IN custbuss.createtime%TYPE,
aCustTel IN custbuss.CustTel%TYPE,--客户电话
aContact IN custbuss.Contact%TYPE,--联系人
aFeedback IN custbuss.Feedback%TYPE,--客户反馈
asid OUT custbuss.ID%TYPE,
RESULT OUT INTEGER
)
IS
BEGIN
RESULT := -1;
SELECT getarea || TO_CHAR (idseq.NEXTVAL, 'FM0999999999')
INTO asid
FROM DUAL;
INSERT INTO custbuss
(ID, custid, businessname, opid, createtime,CustTel,Contact,Feedback
)
VALUES (asid, acustid, bussname, aopid, acreatetime,aCustTel,aContact,aFeedback
);
RESULT := 0;
EXCEPTION
WHEN OTHERS
THEN
RESULT := -1;
END addcustbuss;
查看触发器 定义语句
SQL> SELECT text FROM ALL_SOURCE where TYPE='TRIGGER' AND NAME ='TRDB_TEAM';
二. 通过 DBMS_METADATA 包
Oracle 的在线文档,对这个包有详细说明:
通过该dbms_metadata 包的get_ddl() 方法,我们可以查看表,索引,视图,存储过程等的定义语句。
SQL> select dbms_metadata.get_ddl('object_type','name','user_name') from dual;
1. 查看表的定义语句
SQL> set long 9999999
SQL> select dbms_metadata.get_ddl('TABLE','BBS','NEWCCS') from dual;
DBMS_METADATA.GET_DDL('TABLE','BBS','NEWCCS')
--------------------------------------------------------------------------------
CREATE TABLE "NEWCCS"."BBS"
( "BBSID" NUMBER(16,0),
"SENDER" VARCHAR2(20) NOT NULL ENABLE,
"INCEPT" VARCHAR2(20) NOT NULL ENABLE,
"MSGTITLE" VARCHAR2(40) NOT NULL ENABLE,
"MSG" VARCHAR2(500),
"SENDTIME" DATE DEFAULT sysdate NOT NULL ENABLE,
"MSGTOP" VARCHAR2(1) DEFAULT 0,
"MSGFILENAME" VARCHAR2(100),
