使用dbms_pumpdata执行expdp操作
set serverout on
declare
h1 number; -- Datapump handle
dir_name varchar2(30); -- Directory Name
job_status VARCHAR2(30);
begin
dir_name := 'DATA_PUMP_DIR';
h1 := dbms_datapump.open(
operation =>'EXPORT', --是export还是impport
--导出表配置
job_mode =>'TABLE', --job_mode可以为SCHEMA/TABLE等
--导出用户配置
job_mode =>'SCHEMA',
remote_link => NULL, --是否使用dblink导出(就是NETWORK_LINK）
job_name =>'TABLE_XFF' --job_name expdpjob的名称
);
dbms_datapump.add_file(handle =>h1,
filename => 'XIFENFEI.DMP',
directory => dir_name,
filetype => DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE,
reusefile => 1); -- value of 1 instructs to overwrite existing file
dbms_datapump.add_file(handle =>h1,
filename => 'XIFENFEI.LOG',
directory => dir_name,
filetype => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE,
reusefile => 1);
--导出表配置
dbms_datapump.metadata_filter(handle =>h1,
name => 'TABLE_FILTER',
value => 'CHF.T_XIFENFEI');
--导出用户配置
dbms_datapump.metadata_filter (handle => dp_handle,
name => 'SCHEMA_EXPR',
value => 'IN (''CHF'')');
-- Start the job.
dbms_datapump.start_job(h1);
dbms_datapump.wait_for_job (handle => dp_handle,
job_state => job_status);
dbms_output.put_line ('DataPump Export - '||to_char(sysdate,'DD/MM/YYYY HH24:MI:SS')||' Status '||job_status);
begin
dbms_datapump.detach(handle => h1);
end;
end;
