Examples herein share a method of using PL / SQL export and import data from an Oracle database, for your reference, as follows
1. Export data:
One way: Tools -> Export User Objects -> Export .sql file
Note: This table was built way to export statements and stored procedures statement
Second way: Tools -> Export Table
NOTE: This is the structure and data export table
The first way to export .dmp file formats, .dmp are binary files, cross-platform, but also includes rights, good efficiency, with the most widely used.
A second way to export .sql file format, available text editor to view, better versatility, efficiency is not as good as the first, for a small amount of data import and export. In particular, note that the table can not have a big field (blob, clob, long), if any, will prompt can not be exported (tips are as follows: table contains one or more LONG columns can not export in sql format, user Pl / sql developer format instead) .
The third way to export .pde format files, .pde for the PL / SQL Developer's own file format, only with PL SQL Developer tool to import / export, can not be viewed with a text editor.
2. Data Import (Tools → Import Tables ...)
1. Import oracle .dmp file type.
2. Import .sql types of oracle file.
3. Import .pde type of oracle file.
