Data Pump sqlfile parameter tips

Oracle Database Tips by Donald BurlesonJuly 21, 2015

Question:  In the old import utility we were able to use "show=y" to see the DDL contents of an export dump file.  What is the equivalent in Data Pump?

Answer:  In Data Pump import (impdp) made several great improvements:

  • The dump file is now in XML, and you can browser a dump file to see the contents.
  • The show=y has been replaced by the sqlfile argument.

Here is an example of using the sqlfile parameter with impdp to display the DDL within an Data Pump Export (expdp) file named myexp.dmp:

$ impdp directory=expdir dumpfile=myexp.dmp sqlfile=ddl.sql

In this example, the impdp does not actually perform an import of the contents of the dump file.  Rather, the sqlfile parameter create a script named ddl.sql that contains all DDL from within the export dump file.

Also see how using the sqlfile parameter is useful when gathering arguments for the dbms_datapump metadata_remap procedure.
