If you only export the table structure (Table creation statement) and do not export the table data, you can use tools -- Export user objects.

Select the table to be exported, set the export path and parameters, and click "Export ".

PS: This method can only export tables belonging to this user. Tables of other users cannot be exported. We recommend using command line Export (exp, IMP)

You can use tools -- export tables to export all the table structures, table data, triggers, and functions.

You can select multiple tables to export. There are three export methods:

Oracle export, SQL insert, PL/SQL developer
The first is the file format exported as. dmp. The. dmp file is binary and can be cross-platform and contain permissions, which is very efficient and widely used.

The second type is exported as a. SQL file, which can be viewed in a text editor and has good versatility, but is not as efficient as the first type. It is suitable for importing and exporting small data volumes. Note that there cannot be large fields (blob, clob) in the table. If so, you will be prompted not to export them. You can export them in the first and third ways.

Third, export. ,. you can only use PL/SQL developer to import and export files in the format of PL/SQL developer. You cannot use the editor to view the files.

PS: The table structure and index structure remain unchanged after the "Oracle export" method is used for export and re-import. The other two methods both change the index type.

The import is the same as the export.
