如何生成Oracle模式的整个DDL（可编写脚本）？-Java 学习之路

谁能告诉我如何为Oracle模式中的所有表，视图，索引，包，过程，函数，触发器，类型，序列，同义词，授权等生成DDL？理想情况下，我也想复制行，但这不太重要 .

我希望在某种类型的预定作业上执行此操作，而不是每次都手动执行此操作，以便在SQL Developer中使用向导进行排除 .

理想情况下，因为我将在几个具有相互授予和同义词的模式上运行它，我想有一种方法在输出中进行查找/替换，因此模式名称匹配我的新模式的名称成为 .

谢谢！

PACKAGE的get_ddl过程将返回spec AND body，因此最好更改all_objects上的查询，以便select不返回包体 .

到目前为止，我将查询更改为：
```
SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type, ' ', '_'), object_name, owner)
FROM all_OBJECTS
WHERE (OWNER = 'OWNER1')
and object_type not like '%PARTITION'
and object_type not like '%BODY'
order by object_type, object_name;
```
虽然可能需要进行其他更改，具体取决于您获得的对象类型...

您可以通过SQL * Plus和dbms_metadata包将模式假脱机到文件 . 然后通过sed将模式名称替换为另一个模式名称 . 这适用于Oracle 10及更高版本 .

sqlplus<<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',

            'CHAIN',              'PROCOBJ',
            'PROGRAM',            'PROCOBJ',
            'PACKAGE',            'PACKAGE_SPEC',
            'PACKAGE BODY',       'PACKAGE_BODY',
            'TYPE',               'TYPE_SPEC',
            'TYPE BODY',          'TYPE_BODY',
            'MATERIALIZED VIEW',  'MATERIALIZED_VIEW',
            'QUEUE',              'AQ_QUEUE',

            'JAVA SOURCE',        'JAVA_SOURCE',

            'XML SCHEMA',         'XMLSCHEMA',
            object_type
        ) object_type
    from dba_objects 
    where owner in ('OWNER1')
        --These objects are included with other object types.
        and object_type not in ('INDEX PARTITION','INDEX SUBPARTITION',
           'LOB','LOB PARTITION','TABLE PARTITION','TABLE SUBPARTITION')
        --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)
        --Exclude 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

将所有内容放在脚本中并通过cron（scheduler）运行 . 使用高级功能时，导出对象可能会非常棘手 . 如果您需要为上述代码添加更多例外，请不要感到惊讶 .

如果要为每个对象单独生成ddl，

查询是：

--GENERATE DDL FOR ALL USER OBJECTS

--1. FOR ALL TABLES

SELECT DBMS_METADATA.GET_DDL('TABLE', TABLE_NAME) FROM USER_TABLES;

--2. FOR ALL INDEXES

SELECT DBMS_METADATA.GET_DDL('INDEX', INDEX_NAME) FROM USER_INDEXES WHERE INDEX_TYPE ='NORMAL';

--3. FOR ALL VIEWS

SELECT DBMS_METADATA.GET_DDL('VIEW', VIEW_NAME) FROM USER_VIEWS;

要么

SELECT TEXT FROM USER_VIEWS

--4. FOR ALL MATERILIZED VIEWS

SELECT QUERY FROM USER_MVIEWS

--5. FOR ALL FUNCTION

SELECT DBMS_METADATA.GET_DDL('FUNCTION', OBJECT_NAME) FROM USER_PROCEDURES WHERE OBJECT_TYPE = 'FUNCTION'

================================================== =============================================

GET_DDL 函数不支持某些object_type，如LOB，MATERIALIZED VIEW，TABLE PARTITION

因此，生成DDL的合并查询将是：

SELECT OBJECT_TYPE, OBJECT_NAME,DBMS_METADATA.GET_DDL(OBJECT_TYPE, OBJECT_NAME, OWNER)
  FROM ALL_OBJECTS 
  WHERE (OWNER = 'XYZ') AND OBJECT_TYPE NOT IN('LOB','MATERIALIZED VIEW', 'TABLE PARTITION') ORDER BY OBJECT_TYPE, OBJECT_NAME;

PACKAGE_BODY等对象存在问题：

SELECT DBMS_METADATA.get_ddl(object_Type, object_name, owner) FROM ALL_OBJECTS WHERE OWNER = 'WEBSERVICE';


ORA-31600 invalid input value PACKAGE BODY parameter OBJECT_TYPE in function GET_DDL
ORA-06512: на  "SYS.DBMS_METADATA", line 4018
ORA-06512: на  "SYS.DBMS_METADATA", line 5843
ORA-06512: на  line 1
31600. 00000 -  "invalid input value %s for parameter %s in function %s"
*Cause:    A NULL or invalid value was supplied for the parameter.
*Action:   Correct the input value and try the call again.



SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type,' ','_'), object_name, owner)
  FROM all_OBJECTS 
  WHERE (OWNER = 'OWNER1');

首先导出模式元数据，然后使用sqlfile选项导入（它不会导入数据，只是它会将模式的ddl写入该文件）

示例： - expdp dumpfile=filename logfile=logname directory=dir name schemas=schema name

username:/ as sysdba

impdp dumpfile=filename logfile=logname directory=dir sqlfile=sql.log

username:/ as sysdba

要为整个 SCHEMA （即 USER ）生成DDL脚本，可以使用 dbms_metadata.get_ddl .

在Tim Hall创建的 SQL*Plus 中执行以下脚本：

出现提示时提供 username .

set long 20000 longchunksize 20000 pagesize 0 linesize 1000 feedback off verify off trimspool on
column ddl format a1000

begin
   dbms_metadata.set_transform_param (dbms_metadata.session_transform, 'SQLTERMINATOR', true);
   dbms_metadata.set_transform_param (dbms_metadata.session_transform, 'PRETTY', true);
end;
/

variable v_username VARCHAR2(30);

exec:v_username := upper('&1');

select dbms_metadata.get_ddl('USER', u.username) AS ddl
from   dba_users u
where  u.username = :v_username
union all
select dbms_metadata.get_granted_ddl('TABLESPACE_QUOTA', tq.username) AS ddl
from   dba_ts_quotas tq
where  tq.username = :v_username
and    rownum = 1
union all
select dbms_metadata.get_granted_ddl('ROLE_GRANT', rp.grantee) AS ddl
from   dba_role_privs rp
where  rp.grantee = :v_username
and    rownum = 1
union all
select dbms_metadata.get_granted_ddl('SYSTEM_GRANT', sp.grantee) AS ddl
from   dba_sys_privs sp
where  sp.grantee = :v_username
and    rownum = 1
union all
select dbms_metadata.get_granted_ddl('OBJECT_GRANT', tp.grantee) AS ddl
from   dba_tab_privs tp
where  tp.grantee = :v_username
and    rownum = 1
union all
select dbms_metadata.get_granted_ddl('DEFAULT_ROLE', rp.grantee) AS ddl
from   dba_role_privs rp
where  rp.grantee = :v_username
and    rp.default_role = 'YES'
and    rownum = 1
union all
select to_clob('/* Start profile creation script in case they are missing') AS ddl
from   dba_users u
where  u.username = :v_username
and    u.profile <> 'DEFAULT'
and    rownum = 1
union all
select dbms_metadata.get_ddl('PROFILE', u.profile) AS ddl
from   dba_users u
where  u.username = :v_username
and    u.profile <> 'DEFAULT'
union all
select to_clob('End profile creation script */') AS ddl
