檢視錶，儲存過程，觸發器定義的方法

一．通過 all_source 表

先來確認下，通過all_source 表可以檢視哪些型別的物件：

SQL> SELECT distinct type FROM ALL_SOURCE;

TYPE

------------

PROCEDURE

PACKAGE

PACKAGE BODY

LIBRARY

TYPE BODY

TRIGGER

FUNCTION

JAVA SOURCE

TYPE

從以上的結果我們可以看到，我們可以通過該表查詢的物件.

檢視儲存過程定義語句：

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,--客戶電話

aContact IN custbuss.Contact%TYPE,--聯絡人

aFeedback IN custbuss.Feedback%TYPE,--客戶反饋

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;

已選擇32行。

SQL>

檢視觸發器定義語句

SQL> SELECT text FROM ALL_SOURCE where TYPE='TRIGGER' AND NAME ='TRDB_TEAM';

TEXT

-----------------------------------------------------------------------------

TRIGGER "NEWCCS".trdb_team

BEFORE DELETE

ON team

REFERENCING NEW AS NEW OLD AS OLD

FOR EACH ROW

BEGIN

DELETE FROM team_teamgroup_map

WHERE teamid = :OLD.teamid;

END trdb_team;

已選擇10行。

方法也比較簡單，修改TYPE 和 NAME 就可以。注意要大寫。

二．通過 DBMS_METADATA 包

通過dbms_metadata 包的get_ddl（）方法，我們可以檢視錶，索引，檢視，儲存過程等的定義語句。
用法：

SQL> select dbms_metadata.get_ddl('物件型別','名稱','使用者名稱') from dual;

1. 檢視錶的定義語句
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),

"MSGFILE" LONG RAW,

"EDITTIME" DATE DEFAULT sysdate,

CONSTRAINT "PK_BBS" PRIMARY KEY ("BBSID")

USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS

STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645

PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE

DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE "NEWCCS" ENABLE

) SEGMENT CREATION IMMEDIATE

PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING

STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645

PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE

DEFAULT CELL_FLASH_CACHE DEFAULT)

TABLESPACE "NEWCCS"

SQL>

從上面的查詢可以看到，返回的結果裡面含有一些storage 屬性，看起來很不舒服。我們可以通過設定會話級別來不顯示這些storage 屬性。

Example: Fetch the DDL for all Complete Tables in the Current Schema, Filter Out Nested Tables and Overflow Segments

This example fetches the DDL for all "complete" tables in the current schema, filtering out nested tables and overflow segments. The example uses SET_TRANSFORM_PARAM (with the handle value = DBMS_METADATA.SESSION_TRANSFORM meaning "for the current session") to specify that storage clauses are not to be returned in the SQL DDL. Afterwards, the example resets the session-level parameters to their defaults.

To generate complete, uninterrupted output, set the PAGESIZE to 0 and set LONG to some large number, as shown, before executing your query.

SQL> SET LONG 2000000

SQL> SET PAGESIZE 0

SQL> EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'

STORAGE',false);

PL/SQL 過程已成功完成。

SQL> select dbms_metadata.get_ddl('TABLE','BBS','NEWCCS') from dual;

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),

"MSGFILE" LONG RAW,

"EDITTIME" DATE DEFAULT sysdate,

CONSTRAINT "PK_BBS" PRIMARY KEY ("BBSID")

USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS

TABLESPACE "NEWCCS" ENABLE

) SEGMENT CREATION IMMEDIATE

PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING

TABLESPACE "NEWCCS"

SQL> EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'

DEFAULT');

PL/SQL 過程已成功完成。

2. 檢視儲存過程的定義語句

SQL> SET LONG 9999

SQL> select dbms_metadata.get_ddl('PROCEDURE','ANALYZEDB','NEWCCS') from dual;

CREATE OR REPLACE PROCEDURE "NEWCCS"."ANALYZEDB"

IS

CURSOR get_ownertable

IS

SELECT table_name

FROM user_tables;

ownertable get_ownertable%ROWTYPE;

BEGIN

OPEN get_ownertable;

LOOP

FETCH get_ownertable

INTO ownertable;

EXIT WHEN get_ownertable%NOTFOUND;

EXECUTE IMMEDIATE 'analyze table '

|| ownertable.table_name

|| ' compute statistics for table for all indexes for all indexed columns ';

END LOOP;

EXCEPTION

WHEN OTHERS

THEN

RAISE;

END;
