Oracle PL/SQL 调用数据泵data pump SCHEMA导出

Data Pump API

 

Along with the data pump utilities Oracle provide an PL/sql API. The following is an example of how this API can be used to perform a schema export.

SET SERVEROUTPUT ON SIZE 1000000
DECLARE
  l_dp_handle       NUMBER;
  l_last_job_state  VARCHAR2(30) := 'UNDEFINED';
  l_job_state       VARCHAR2(30) := 'UNDEFINED';
  l_sts             KU$_STATUS;
BEGIN
  l_dp_handle := DBMS_DATAPUMP.open(
    operation   => 'EXPORT',job_mode    => 'SCHEMA',remote_link => NULL,job_name    => 'EMP_EXPORT',version     => 'LATEST');

  DBMS_DATAPUMP.add_file(
    handle    => l_dp_handle,filename  => 'SCott.dmp',directory => 'DATA_PUMP_DIR');
  DBMS_DATAPUMP.add_file(
    handle    => l_dp_handle,filename  => 'SCott.log',directory => 'DATA_PUMP_DIR',    filetype  => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE);

  DBMS_DATAPUMP.Metadata_filter(
    handle => l_dp_handle,name   => 'SCHEMA_EXPR',value  => '= ''SCott''');

  DBMS_DATAPUMP.start_job(l_dp_handle);

  DBMS_DATAPUMP.detach(l_dp_handle);
END;
/

Once the job has started the status can be checked using.
