By using bat batch processing, visual operations on oracle backup files in dmp format of oracle are generally borrowed from PL/SQL. Now we need to export the oracle dmp backup file at the same time, and just use his command to create a bat batch processing file, the content is as follows: sqlplus sys/sys user password @ database as sysdba @ e: \ import \ d. SQL imp \ "userid = db username/db password as sysdba \" full = y file = e: \ import \ ww_1.dmp imp \ "userid = db username/db password as sysdba \" full = y file = e: \ import \ ww_2.dmp imp \ "userid = db username/db password as sysdba \" full = y file = e: \ import \ ww_3.dmp d. the SQL statement is as follows: drop table sys. vio_1; drop table sys. vio2; drop table sys. vio3; quit; batch processing files and d. put the SQL and cmdel backup files in the e: \ import folder and run the bat batch file to import the files.
