Oracle中如何導(dǎo)出存儲(chǔ)過(guò)程、函數(shù)、包和觸發(fā)器的定義語(yǔ)句？如何導(dǎo)出表的結(jié)構(gòu)？如何導(dǎo)出索引的創(chuàng)建語(yǔ)句？

Oracle中如何導(dǎo)出存儲(chǔ)過(guò)程、函數(shù)、包和觸發(fā)器的定義語(yǔ)句？如何導(dǎo)出表的結(jié)構(gòu)？如何導(dǎo)出索引的創(chuàng)建語(yǔ)句？

QQ群里有人問(wèn)：如何導(dǎo)出一個(gè)用戶下的存儲(chǔ)過(guò)程？

? 麥苗答：方法有多種，可以使用DBMS_METADATA.GET_DDL包。

使用PL/SQL DEVELOPER工具

-- 下面的SQL語(yǔ)句，如果報(bào)錯(cuò)：ORA-22835: 緩沖區(qū)對(duì)于 CLOB 到 CHAR 轉(zhuǎn)換或 BLOB 到 RAW 轉(zhuǎn)換而言太小 (實(shí)際: 4994, 最大: 4000)，那么去掉TO_CAHR

SELECT TO_CHAR(DBMS_METADATA.GET_DDL('PROCEDURE', U.OBJECT_NAME)) ||CHR(10)||'/'

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'PROCEDURE'

?;


然后將結(jié)果拷貝到Excel中，

打開Excel，復(fù)制內(nèi)容到plsql developer里邊，注意粘貼的時(shí)候使用右鍵的“Past from host Language”，否則粘貼后的代碼含有雙引號(hào)：

? 運(yùn)行這些腳本腳本即可：

使用SQL*Plus

使用如下的腳本即可導(dǎo)出某個(gè)用戶下的存儲(chǔ)過(guò)程代碼到/tmp/a.sql文件中：

SET PAGESIZE 0

SET TRIMSPOOL ON

SET LINESIZE 10000

SET LONG 90000

SET FEEDBACK OFF

SET FEED OFF;

SET ECHO OFF

spool /tmp/a.sql

SELECT DBMS_METADATA.GET_DDL('PROCEDURE', U.OBJECT_NAME)||CHR(10)||'/'

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'PROCEDURE';?

spool OFF

打開文件后，簡(jiǎn)單處理一下即可。

總體來(lái)說(shuō)有兩種方式來(lái)獲取，第一，利用系統(tǒng)包DBMS_METADATA包中的GET_DDL函數(shù)來(lái)獲取，第二，利用exp或expdp來(lái)獲取。

下面來(lái)看第一種方式，如何利用系統(tǒng)包DBMS_METADATA包中的GET_DDL函數(shù)來(lái)獲取對(duì)象的定義語(yǔ)句。下面是該函數(shù)的入?yún)⒑统鰠ⅲ?/p>

SQL> DESC DBMS_METADATA.GET_DDL

PARAMETER?? TYPE???? MODE DEFAULT?

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

(RESULT)??? CLOB??????????????????

OBJECT_TYPE VARCHAR2 IN???????????

NAME??????? VARCHAR2 IN???????????

SCHEMA????? VARCHAR2 IN?? Y???????

VERSION???? VARCHAR2 IN?? Y???????

MODEL?????? VARCHAR2 IN?? Y???????

TRANSFORM?? VARCHAR2 IN?? Y???????

其詳細(xì)參數(shù)如下：

l?OBJECT_TYPE?需要返回原數(shù)據(jù)的DDL語(yǔ)句的對(duì)象類型

l?NAME?對(duì)象名稱

l?SCHEMA?對(duì)象所在的SCHEMA，默認(rèn)為當(dāng)前用戶所在所SCHEMA

l?VERSION?對(duì)象原數(shù)據(jù)的版本

l?MODEL?原數(shù)據(jù)的類型默認(rèn)為ORACLE

l?TRANSFORM?默認(rèn)值為DDL

l?RETURNS?對(duì)象的原數(shù)據(jù)默認(rèn)以CLOB類型返回

一般情況下，只需要給出OBJECT_TYPE、NAME和SCHEMA3個(gè)參數(shù)即可。

SELECT DBMS_METADATA.GET_DDL('INDEX','PK_DEPT','SCOTT') FROM DUAL;

SELECT DBMS_METADATA.GET_DDL('INDEX',U.INDEX_NAME) FROM USER_INDEXES U;

n?查看創(chuàng)建主鍵的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('CONSTRAINT','EMP_PK') FROM DUAL;

n?查看創(chuàng)建外鍵的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('REF_CONSTRAINT','EMP_FK_DEPT') FROM DUAL;

SELECT DBMS_METADATA.GET_DDL('VIEW', 'MY_TABLES','SCOTT') FROM DUAL;

SELECT DBMS_METADATA.GET_DDL('VIEW', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'VIEW';

SELECT TEXT FROM USER_VIEWS WHERE VIEW_NAME=UPPER('&VIEW_NAME');

SELECT DBMS_METADATA.GET_DDL('PROCEDURE', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'PROCEDURE';

n?查看創(chuàng)建觸發(fā)器（TRIGGER）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('TRIGGER', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'TRIGGER';

n?查看創(chuàng)建函數(shù)（FUNCTION）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('FUNCTION', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'FUNCTION';

n?查看創(chuàng)建包（PACKAGE）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('PACKAGE', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'PACKAGE';

n?查看創(chuàng)建序列（SEQUENCE）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('SEQUENCE', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'SEQUENCE';

n?查看創(chuàng)建同義詞（SYNONYM）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('SYNONYM', U.OBJECT_NAME)

? FROM USER_OBJECTS U

?WHERE OBJECT_TYPE = 'SYNONYM';

n?查看創(chuàng)建表空間（TABLESPACE）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('TABLESPACE', U.TABLESPACE_NAME)

? FROM USER_TABLESPACES U;

n?查看創(chuàng)建角色（ROLE）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('ROLE', U.ROLE) FROM DBA_ROLES U;

n?查看創(chuàng)建用戶（USER）的SQL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('USER','SYS') FROM DUAL;

n?得到某個(gè)SCHEDULER JOB的創(chuàng)建語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL('PROCOBJ', D.JOB_NAME, D.OWNER)

? FROM DBA_SCHEDULER_JOBS D

?WHERE D.JOB_TYPE = 'STORED_PROCEDURE'

?? AND D.STATE = 'SCHEDULED'

?? AND D.SCHEDULE_NAME IS NULL;

n?得到一個(gè)用戶下的所有表、索引、存儲(chǔ)過(guò)程、函數(shù)的DDL語(yǔ)句：

SELECT DBMS_METADATA.GET_DDL(U.OBJECT_TYPE, U.OBJECT_NAME)

FROM?? USER_OBJECTS U

WHERE? U.OBJECT_TYPE IN ('TABLE', 'INDEX', 'PROCEDURE', 'FUNCTION');

如果想去掉表的存儲(chǔ)參數(shù)（例如，INITIAL、NEXT、FREELISTS等參數(shù)），那么可以使用DBMS_METADATA包中的函數(shù)SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'STORAGE',FALSE)來(lái)完成，代碼如下所示：

SYS@lhrdb> SELECT DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT') FROM DUAL;

DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT')

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

? CREATE TABLE "SCOTT"."DEPT"

使用DBMS_METADATA.GET_DDL需要注意以下問(wèn)題：

（1）DBMS_METADATA.GET_DDL()包內(nèi)的參數(shù)都要大寫，否則會(huì)報(bào)ORA-31600: invalid input value table for parameter OBJECT_TYPE in function GET_DDL的錯(cuò)誤。

（2）是否查的當(dāng)前用戶的DDL語(yǔ)句，若不是則需要加上對(duì)象的屬主信息即SCHEMA參數(shù)。

（3）若在SQL*Plus中顯示不全，則需要set long 9999。

（4）對(duì)于DBMS_METADATA.GET_DDL包，可以在PLSQL Developer工具中運(yùn)行，也可以在SQL*Plus中運(yùn)行。

如果要導(dǎo)出SCOTT用戶下的所有定義，那么在SQL*Plus中代碼如下所示：

SET PAGESIZE 0

SET TRIMSPOOL ON

SET LINESIZE 10000

SET LONG 90000

SET FEEDBACK OFF

SET FEED OFF;

SET ECHO OFF

SPOOL /tmp/schema_scott.sql

SELECT CASE

???????? WHEN U.OBJECT_TYPE IN

('PROCEDURE', 'FUNCTION'?，?'PACKAGE', 'TRIGGER') THEN

????????? DBMS_METADATA.GET_DDL(U.OBJECT_TYPE, U.OBJECT_NAME, U.OWNER) ||

????????? CHR(10) || '/'

???????? ELSE

????????? DBMS_METADATA.GET_DDL(U.OBJECT_TYPE, U.OBJECT_NAME, U.OWNER)||

????????? CHR(10) || ';'

?????? END AS SCOTT_DDL

? FROM DBA_OBJECTS U

?WHERE U.OBJECT_TYPE IN

('TABLE', 'INDEX', 'PROCEDURE', 'FUNCTION'?，?'PACKAGE', 'TRIGGER')

AND U.OWNER='SCOTT';

SPOOL OFF;

則可以導(dǎo)出SCOTT用戶下所有的DDL語(yǔ)句到/tmp/schema_scott.sql文件中。

如果在PLSQL Developer工具中運(yùn)行，那么可以單獨(dú)運(yùn)行如下的SQL語(yǔ)句：

SELECT CASE

???????? WHEN U.OBJECT_TYPE IN

('PROCEDURE', 'FUNCTION'?，?'PACKAGE', 'TRIGGER') THEN

????????? DBMS_METADATA.GET_DDL(U.OBJECT_TYPE, U.OBJECT_NAME, U.OWNER) ||

????????? CHR(10) || '/'

???????? ELSE

????????? DBMS_METADATA.GET_DDL(U.OBJECT_TYPE, U.OBJECT_NAME, U.OWNER)||

????????? CHR(10) || ';'

?????? END AS SCOTT_DDL

? FROM DBA_OBJECTS U

?WHERE U.OBJECT_TYPE IN

('TABLE', 'INDEX', 'PROCEDURE', 'FUNCTION'?，?'PACKAGE', 'TRIGGER')

AND U.OWNER='SCOTT';

然后選擇整列，右鍵選擇“Copy to Excel”，就可以將數(shù)據(jù)導(dǎo)出到Excel文件中，接著，將Excel中的數(shù)據(jù)復(fù)制到PLSQL Developer工具的“SQL Window”中皆可。需要注意的是，最后復(fù)制到“SQL Window”中的時(shí)候，需要選擇右鍵的“Past from host Language”，否則粘貼的代碼含有雙引號(hào)，需要做特殊處理，比較麻煩。

?可以使用如下的SQL腳本生成某個(gè)用戶下的所有對(duì)象的DDL語(yǔ)句：

下面介紹第二種導(dǎo)出元數(shù)據(jù)的方法，就是采用exp或expdp命令。數(shù)據(jù)泵工具（impdp）提供了SQLFILE的命令行選項(xiàng)，只獲取DDL語(yǔ)句，并未真正地執(zhí)行數(shù)據(jù)導(dǎo)入。另外，若單純?yōu)榱藢?dǎo)出DDL語(yǔ)句則可以在使用expdp導(dǎo)出的時(shí)候使用CONTENT=METADATA_ONLY和EXCLUDE=STATISTICS選項(xiàng)，這樣導(dǎo)出的DMP文件比較小。如下所示：

expdp \'/ AS SYSDBA\' DIRECTORY=DATA_PUMP_DIR DUMPFILE=lhrsql20161215.dmp LOGFILE=lhrsql20161215.log CONTENT=METADATA_ONLY SCHEMAS=SCOTT? EXCLUDE=STATISTICS

impdp? \'/ AS SYSDBA\'? DIRECTORY=DATA_PUMP_DIR DUMPFILE=lhrsql20161215.dmp? LOGFILE=imp_exptest.log SQLFILE=expddl_lhr.sql

查看expddl_lhr.sql文件即可獲取DDL語(yǔ)句。整個(gè)示例如下所示：

《《《《。。。。。。。。篇幅原因，有省略,剩下的都是統(tǒng)計(jì)信息，生成sqlfile的時(shí)候也可以不用生成。。。。。。。。》》》》

imp工具使用SHOW=Y LOG=GET_DDL.sql的方式，可以看到清晰的DDL腳本，同時(shí)也不會(huì)真正的執(zhí)行數(shù)據(jù)導(dǎo)入。另外，若單純?yōu)榱藢?dǎo)出DDL語(yǔ)句則可以在使用exp導(dǎo)出的時(shí)候使用ROWS=N選項(xiàng)，這樣導(dǎo)出的DMP文件比較小。如下所示：

exp? \'/ AS SYSDBA\'? TABLES=SCOTT.EMP? FILE=/tmp/exp_ddl_lhr_01.dmp? LOG=/tmp/exp_table.log? BUFFER=41943040 ROWS=N COMPRESS=N

imp \'/ AS SYSDBA\' FILE=/tmp/exp_ddl_lhr_01.dmp SHOW=Y LOG=/tmp/get_ddl.sql BUFFER=20480000? FULL=Y

查看get_ddl.sql文件即可獲取DDL語(yǔ)句。不過(guò)對(duì)于exp生成的DDL語(yǔ)句不能直接使用，需要使用SHELL腳本做相應(yīng)的處理后才能使用。整個(gè)示例如下所示：
