如何生成一个Oracle模式的完整DDL（可编写脚本）？
任何人都可以告诉我如何可以在Oracle架构内为所有表，视图，索引，包，程序，函数，触发器，types，序列，同义词，授权等生成DDL？ 理想情况下，我想复制行，但这不重要。
我想在某种计划的工作上做这个，而不是每次都手动完成，这样就排除了在SQL Developer中使用向导。
理想情况下，因为我将在几个有相互授权和同义词的模式上运行这个，所以我想有一种方法来在输出中进行查找/replace，以使模式名称与我的新模式名称匹配成为。
谢谢！
您可以通过SQL * Plus和dbms_metadata软件包将模式转换为文件。 然后通过sedreplace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', 'EVALUATION CONTEXT', 'PROCOBJ', 'PACKAGE', 'PACKAGE_SPEC', 'PACKAGE BODY', 'PACKAGE_BODY', 'TYPE', 'TYPE_SPEC', 'TYPE BODY', 'TYPE_BODY', 'MATERIALIZED VIEW', 'MATERIALIZED_VIEW', 'QUEUE', 'AQ_QUEUE', 'JAVA CLASS', 'JAVA_CLASS', 'JAVA TYPE', 'JAVA_TYPE', 'JAVA SOURCE', 'JAVA_SOURCE', 'JAVA RESOURCE', 'JAVA_RESOURCE', 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 把所有东西放在脚本中，并通过cron（scheduler）运行。 使用高级function时，导出对象可能会非常棘手。 如果您需要在上面的代码中添加更多的例外，请不要惊讶。
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');
一个PACKAGE的get_ddl过程将同时返回spec和body，所以最好在all_objects上改变查询，这样包体不会在select上返回。
到目前为止，我改变了这个查询：
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;
虽然可能需要根据所获得的对象types进行其他更改…
如果你想单独为每个对象生成ddl，
查询是：
– 为所有用户对象生成DDL
–1。 适用于所有表格
SELECT DBMS_METADATA.GET_DDL('TABLE', TABLE_NAME) FROM USER_TABLES;
–2。 适用于所有指标
SELECT DBMS_METADATA.GET_DDL('INDEX', INDEX_NAME) FROM USER_INDEXES WHERE INDEX_TYPE ='NORMAL';
–3。 为所有视图
SELECT DBMS_METADATA.GET_DDL('VIEW', VIEW_NAME) FROM USER_VIEWS;
要么
SELECT TEXT FROM USER_VIEWS
–4。 所有的材料化视图
SELECT QUERY FROM USER_MVIEWS
–5。 为所有function
SELECT DBMS_METADATA.GET_DDL('FUNCTION', OBJECT_NAME) FROM USER_PROCEDURES WHERE OBJECT_TYPE = 'FUNCTION'
================================================== =============================================
GET_DDL函数不支持像LOB，MATERIALIZED VIEW，TABLE PARTITION这样的object_type
SO，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;
首先导出架构元数据，然后通过使用sqlfile选项导入（它不会导入数据，只会将ddl架构写入该文件）
例如： – 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build的SQL * Plus中执行以下脚本：
