如何导出用户下所有的sequence

skywalker — Tue, 06 Jan 2009 11:23:20 +0000

Oracle的EXP工具只有在全用户导出时，才会包含secquence。在单独需要sequence时，可以用spool和dbms_metadata包来实现。在sqlplus中，首先执行这个脚本 set long 90000 set feedback off set pagesize 0 set heading off spool get_seq_ddl.sql select 'select dbms_metadata.get_ddl('''||t.object_type||''',''' ||t.object_name||''') from dual;' from user_objects t where t.object_type='SEQUENCE'; spool off 再运行新生成的sql脚本，将DDL输出到seq_ddl.sql spool seq_ddl.sql @get_seq_ddl.sql spool off Related posts:drop table遭遇ORA-604 / ORA-1422 笔记：重建用户下所有索引 sqlplus下如何看执行计划 Related posts:
