第二步：判斷表是否可以在線從新定義
begin
dbms_redefinition.can_redef_table('ERPSU','SAP_E_DSOQQZT',DBMS_REDEFINITION.CONS_USE_PK);
end;
第三步：開始執(zhí)行數(shù)據(jù)的遷移（30分鐘）
begin
DBMS_REDEFINITION.START_REDEF_TABLE('ERPSU','SAP_E_DSOQQZT', 'SAP_E_DSOQQZT_TMP');
end;
第四步：進(jìn)行權(quán)限對(duì)象的遷移
DECLARE
num_errors PLS_INTEGER;
BEGIN
DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS('ERPSU','SAP_E_DSOQQZT', 'SAP_E_DSOQQZT_TMP',
DBMS_REDEFINITION.CONS_ORIG_PARAMS, TRUE, TRUE, TRUE, TRUE, num_errors);
END;
第五步：結(jié)束整個(gè)重定義
BEGIN
DBMS_REDEFINITION.FINISH_REDEF_TABLE('ERPSU','SAP_E_DSOQQZT', 'SAP_E_DSOQQZT_TMP');
END;
第六步，刪除臨時(shí)表 SAP_E_DSOQQZT_TMP
萬一哪一步出錯(cuò)，執(zhí)行：
BEGIN
DBMS_REDEFINITION.ABORT_REDEF_TABLE(uname => 'ERPSU',
orig_table => 'SAP_E_DSOQQZT',
int_table => 'SAP_E_DSOQQZT_TMP'
);
END;
