How can Oracle export table structure and table data?
To export the table structure and table data from an Oracle database, you can use either of the following two methods:
- Utilize Oracle’s built-in tools such as SQL Developer or Data Pump to easily export table structures and data.
- Export table structure: In SQL Developer, select the table you want to export, right click on the table name, choose “Export”, then select the export format, file path, and other information, click the “Export” button to export the table structure.
- Export table data: In SQL Developer, select the table from which you want to export data, right-click on the table name, choose “Export”, then select the export format, file path, and other information, check the “Export data” option, and click the “Export” button to export the table data.
- Export using SQL statements: You can manually export table structure and table data using SQL statements.
- Exporting table structure: Use the following SQL statement to export the table structure:
CREATE TABLE table_name AS SELECT * FROM original_table WHERE 1=0;
Where table_name is the name of the exported table, and original_table is the name of the original table. This statement will create a new table with the same structure as the original table but without any data. - Export table data: Use the following SQL statement to export table data:
INSERT INTO new_table SELECT * FROM original_table;In this statement, new_table is the name of the exported table, and original_table is the name of the original table. This statement will insert the data from the original table into the new table.
Regardless of the method used, the exported table structure and table data will be stored in the specified file, which can be used for backing up, migrating, or restoring data.
