求助批處理登錄Oracle失敗后如何執(zhí)行后續(xù)命令RT，以下是部分代碼：

:create1
set /p ORA_SID=Please enter the ORACLE_SID:
@echo.
set /p pass=Please enter the password: 
@echo.
sqlplus sys/%pass%@%ORA_SID% as sysdba @%p%/get_rebuild.sql>nul
for /f usebackq %%b in (`sed -n /.trc/p C:gettrc.txt`) do (set var=%%b)
if exist %var% (
echo Get the control file rebuild scripts from the %ORA_SID% successfully ! &echo.
)else(
echo Get the control file rebuild scripts from the %ORA_SID% failed ! &echo.
echo Please re-enter the ORACLE_SID or verifythe database status is normal ! &echo. 
goto create1
)
goto create2 
nclick="copycode($('code0'));">復(fù)制代碼

目的是登錄Oracle數(shù)據(jù)庫(kù)后獲取某個(gè)文件。問(wèn)題：當(dāng)實(shí)例或者密碼輸入錯(cuò)誤后，腳本會(huì)卡在登錄那個(gè)階段，errorlevel也沒(méi)有返回值，此時(shí)該怎樣跳過(guò)這條命令繼續(xù)執(zhí)行？
