Generate sql file from datapump export

Most of the legacy mode options will work in the data pump with its corresponding options. In legacy mode (imp utility) we have show=y option to spool the content of the dump file into sql scripts without doing the actual import. The same command can be used in data pump impdp also but it will get replaced with sqlfile option.



oracle@Linux01:[/u01/app/oracle/dpump] $ expdp atoorpu directory=DPUMP dumpfile=test1.dmp logfile=test1.log tables=TEST
