This example shares the method of exporting and importing data from Oracle database using PL/SQL for your reference. The specific contents are as follows

1. Export data:

Method 1: Tools-> Export User Objects-> Export.sql File

Note: This method exports table creation statements and stored procedure statements.

Method 2: Tools-> Export Table

Note: Here is the structure and data of the export table

The first way to export.dmp format files,.dmp is a binary file, cross-platform, but also can contain permissions, good efficiency, the most widely used.

The second way to export files in.sql format, available text editor view, versatility is better, efficiency is not as good as the first, suitable for small data import and export. Table contains one or more LONG columns cannot be exported in SQL format,user Pl/SQL developer format instead.

The third way is to export files in.pde format..pde is PL/SQL Developer's own file format, which can only be imported and exported with PL/SQL Developer tools, and cannot be viewed with text editors.

2. Data Import (Tools→Import Tables…)

1. Import an oracle file of type.dmp.

2. Import an oracle file of type.sql.

3. Import an oracle file of type.pde.

The above is all the content of this article, I hope to help everyone's study, but also hope that everyone a lot of support.
