Oracle中如何匯出儲存過程、函式、包和觸發器的定義語句？如何匯出表的結構？如何匯出索引的建立語句？

QQ群裡有人問：如何匯出一個使用者下的儲存過程？
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語句，如果報錯：ORA-22835: 緩衝區對於 CLOB 到 CHAR 轉換或 BLOB 到 RAW 轉換而言太小 (實際: 4994, 最大: 4000)，那麼去掉TO_CAHR

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

 WHERE OBJECT_TYPE = 'PROCEDURE'

 ;

然後將結果複製到Excel中，

開啟Excel，複製內容到plsql developer裡邊，注意貼上的時候使用右鍵的“Past from host Language”，否則貼上後的程式碼含有雙引號：

執行這些指令碼指令碼即可：

使用SQL*Plus

使用如下的指令碼即可匯出某個使用者下的儲存過程程式碼到/tmp/a.sql檔案中：

							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

開啟檔案後，簡單處理一下即可。

總體來說有兩種方式來獲取，第一，利用系統包DBMS_METADATA包中的GET_DDL函式來獲取，第二，利用exp或expdp來獲取。

下面來看第一種方式，如何利用系統包DBMS_METADATA包中的GET_DDL函式來獲取物件的定義語句。下面是該函式的入參和出參：

							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

其詳細引數如下：

l OBJECT_TYPE 需要返回原資料的DDL語句的物件型別

l NAME 物件名稱

l SCHEMA 物件所在的SCHEMA，預設為當前使用者所在所SCHEMA

l VERSION 物件原資料的版本

l MODEL 原資料的型別預設為ORACLE

l TRANSFORM 預設值為DDL

l RETURNS 物件的原資料預設以CLOB型別返回

一般情況下，只需要給出OBJECT_TYPE、NAME和SCHEMA3個引數即可。

n 檢視建立表SQL語句：

								SELECT
DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT') FROM DUAL; 
							
								SELECT DBMS_METADATA.GET_DDL('TABLE',U.TABLE_NAME)
FROM USER_TABLES U;

n 檢視建立索引的SQL語句：

								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 檢視建立主鍵的SQL語句：

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

n 檢視建立外來鍵的SQL語句：

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

n 檢視建立檢視（VIEW）的SQL語句：

								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');

n 檢視建立儲存過程（PROCEDURE）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('PROCEDURE',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'PROCEDURE';

n 檢視建立觸發器（TRIGGER）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('TRIGGER',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'TRIGGER';

n 檢視建立函式（FUNCTION）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('FUNCTION',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'FUNCTION';

n 檢視建立包（PACKAGE）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('PACKAGE',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'PACKAGE';

n 檢視建立序列（SEQUENCE）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('SEQUENCE',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'SEQUENCE';

n 檢視建立同義詞（SYNONYM）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('SYNONYM',
U.OBJECT_NAME) 
							
								  FROM
USER_OBJECTS U 
							
								 WHERE
OBJECT_TYPE = 'SYNONYM';

n 檢視建立表空間（TABLESPACE）的SQL語句：

								SELECT DBMS_METADATA.GET_DDL('TABLESPACE',
U.TABLESPACE_NAME) 
							
								  FROM
USER_TABLESPACES U;

n 檢視建立角色（ROLE）的SQL語句：

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

n 檢視建立使用者（USER）的SQL語句：

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

n 得到某個SCHEDULER JOB的建立語句：

								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 得到一個使用者下的所有表、索引、儲存過程、函式的DDL語句：

								SELECT DBMS_METADATA.GET_DDL(U.OBJECT_TYPE,
U.OBJECT_NAME) 
							
								FROM  
USER_OBJECTS U 
							
								WHERE 
U.OBJECT_TYPE IN ('TABLE', 'INDEX', 'PROCEDURE', 'FUNCTION');

如果想去掉表的儲存引數（例如，INITIAL、NEXT、FREELISTS等引數），那麼可以使用DBMS_METADATA包中的函式SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'STORAGE',FALSE)來完成，程式碼如下所示：

								SYS@lhrdb> SELECT
DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT') FROM DUAL; 
							
								DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT') 
							
								-------------------------------------------------------------------------------- 
							
								  CREATE
TABLE "SCOTT"."DEPT" 
							
								   (    "DEPTNO" NUMBER(2,0), 
							
"DNAME" VARCHAR2(14), 
							
"LOC" VARCHAR2(13), 
							
CONSTRAINT "PK_DEPT" PRIMARY KEY ("DEPTNO") 
							
								  USING INDEX

								DBMS_METADATA.GET_DDL('TABLE','DEPT','SCOTT') 
							
								-------------------------------------------------------------------------------- 
							
								  CREATE
TABLE "SCOTT"."DEPT" 
							
								   (    "DEPTNO" NUMBER(2,0), 
							
"DNAME" VARCHAR2(14), 
							
"LOC" VARCHAR2(13), 
							
CONSTRAINT "PK_DEPT" PRIMARY KEY ("DEPTNO") 
							
								  USING INDEX

使用DBMS_METADATA.GET_DDL需要注意以下問題：

（1）DBMS_METADATA.GET_DDL()包內的引數都要大寫，否則會報ORA-31600: invalid input value table for parameter OBJECT_TYPE in function GET_DDL的錯誤。

（2）是否查的當前使用者的DDL語句，若不是則需要加上物件的屬主資訊即SCHEMA引數。

（3）若在SQL*Plus中顯示不全，則需要set long 9999。

（4）對於DBMS_METADATA.GET_DDL包，可以在PLSQL Developer工具中執行，也可以在SQL*Plus中執行。

如果要匯出SCOTT使用者下的所有定義，那麼在SQL*Plus中程式碼如下所示：

								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;

則可以匯出SCOTT使用者下所有的DDL語句到/tmp/schema_scott.sql檔案中。

如果在PLSQL Developer工具中執行，那麼可以單獨執行如下的SQL語句：

								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';

然後選擇整列，右鍵選擇“Copy to Excel”，就可以將資料匯出到Excel檔案中，接著，將Excel中的資料複製到PLSQL Developer工具的“SQL Window”中皆可。需要注意的是，最後複製到“SQL Window”中的時候，需要選擇右鍵的“Past from host Language”，否則貼上的程式碼含有雙引號，需要做特殊處理，比較麻煩。

可以使用如下的SQL指令碼生成某個使用者下的所有物件的DDL語句：

									sqlplus<<eof <="" eof 
								
									set long 100000 
								
									set head off 
								
									set echo off 
								
									set pagesize 0 
								
									set verify off 
								
									set feedback off 
								
									spool schema.out 
								
									select dbms_metadata.get_ddl(object_type,
object_name, owner) 
								
									from 
								
									( 
								
									    --Convert
DBA_OBJECTS.OBJECT_TYPE to DBMS_METADATA object type: 
								
									    select 
								
owner, 
								
--Java object names may need to be converted with DBMS_JAVA.LONGNAME. 
								
--That code is not included since many database don't have Java
installed. 
								
object_name, 
								
decode(object_type, 
								
'DATABASE LINK',      'DB_LINK', 
								
'JOB',                'PROCOBJ', 
								
'RULE SET',           'PROCOBJ', 
								
'RULE',               'PROCOBJ', 
								
'EVALUATION CONTEXT', 'PROCOBJ', 
								
'PACKAGE',           
'PACKAGE_SPEC',

'JAVA_CLASS', 
								
'JAVA TYPE',          'JAVA_TYPE', 
								
'JAVA SOURCE',        'JAVA_SOURCE', 
								
'JAVA RESOURCE',     
'JAVA_RESOURCE', 
								
object_type 
								
									        )
object_type 
								
									    from
dba_objects  
								
									    where
owner in ('LHR') 
								
--These objects are included with other object types. 
								
									        and
object_type not in ('INDEX PARTITION','INDEX SUBPARTITION', 
								
'LOB','LOB PARTITION','LOB SUBPARTITION','TABLE PARTITION','TABLE
SUBPARTITION','PROGRAM') 
								
--Ignore system-generated types that support collection processing. 
								
									        and
not (object_type = 'TYPE' and object_name like 'SYS_PLSQL_%') 
								
--Exclude nested tables, their DDL is part of their parent table. 
								
									        and
(owner, object_name) not in (select owner, table_name from dba_nested_tables) 
								
--Exlclude overflow segments, their DDL is part of their parent table. 
								
									        and
(owner, object_name) not in (select owner, table_name from dba_tables where
iot_type = 'IOT_OVERFLOW') 
								
									) 
								
									order by owner, object_type, object_name; 
								
									spool off 
								
									quit 
								
									EOF 
								
									cat schema.out|sed 's/OWNER1/MYOWNER/g'>schema.out.change.sql

下面介紹第二種匯出後設資料的方法，就是採用exp或expdp命令。資料泵工具（impdp）提供了SQLFILE的命令列選項，只獲取DDL語句，並未真正地執行資料匯入。另外，若單純為了匯出DDL語句則可以在使用expdp匯出的時候使用CONTENT=METADATA_ONLY和EXCLUDE=STATISTICS選項，這樣匯出的DMP檔案比較小。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 
							

檢視expddl_lhr.sql檔案即可獲取DDL語句。整個示例如下所示：

imp工具使用SHOW=Y LOG=GET_DDL.sql的方式，可以看到清晰的DDL指令碼，同時也不會真正的執行資料匯入。另外，若單純為了匯出DDL語句則可以在使用exp匯出的時候使用ROWS=N選項，這樣匯出的DMP檔案比較小。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 
							

檢視get_ddl.sql檔案即可獲取DDL語句。不過對於exp生成的DDL語句不能直接使用，需要使用SHELL指令碼做相應的處理後才能使用。整個示例如下所示：

								[ZFZHLHRDB1:oracle]:/oracle>exp  \'/ AS SYSDBA\'  tables=scott.emp  file=/tmp/exp_ddl_lhr_01.dmp  log=/tmp/exp_table.log  buffer=41943040 rows=n compress=n

這樣執行起來就方便多了。

另外，使用imp工具的indexfile選項也可以把dmp檔案中的表和索引的建立語句匯出而不匯入任何物件，命令如下：

								imp userid/userid@service_name
file=/tmp/exp_ddl_lhr_01.dmp FULL=Y indexfile=/tmp/get_ti_ddl.sql rows=n 
							

示例如下所示：

								[oracle@rhel6lhr tmp]$ exp  \'/ AS SYSDBA\'  TABLES=SCOTT.EMP  FILE=/tmp/exp_ddl_lhr_01.dmp  LOG=/tmp/exp_table.log  BUFFER=41943040 ROWS=N COMPRESS=N

可以看到其中的建立表的SQL語句被註釋掉了，這個可以用vi命令或者文字工具來處理，處理之後就可以直接使用了。
