Export Oracle Database: A Comprehensive Guide to Import and Export Operations

How to Export and Import Oracle Database

Exporting Database Objects with Oracle SQL Developer

Begin exporting database objects by ensuring you have Oracle SQL Developer and an Oracle Database version 9.2.0.1 or later. Use SQL Developer's export tool to export object definitions. Choose from formats such as CSV, XML, LOADER, TEXT, INSERT, HTML, and XLS for data exportation. Utilize the SQL Worksheet to compose a query or use the Data tab within the table definition, selecting 'Export Data' for exporting from a table.

Importing Database Objects Using Oracle SQL Developer

Oracle SQL Developer 3.0 provides a user-friendly Import and Export wizard to facilitate importing and exporting database objects. Customize your import and export process using this tool to fit your specific needs. Import and export operations can be performed directly from the Data Grid or SQL Worksheet, enhancing the flexibility of managing database objects.

Best Practices for Importing into Oracle Database

Prior to importing, it's crucial to clean your data. Validate functional imports before processing large datasets. Allocate adequate time for planning and refining the import procedure. Oracle advises against importing more than 100,000 records in a single batch and running more than five imports concurrently. For high volume imports, consult with Oracle to ensure proper pod sizing.
