How to Export Oracle Database to CSV

Using SQLcl for Fast Export

Utilize SQLcl's CSV sql format with the parallel hint for the quickest method to export Oracle tables to a CSV file. This approach significantly reduces export time and is ideal for large datasets.

PL/SQL Routine with UTL_FILE

Create a PL/SQL routine leveraging UTL_FILE to export specific data ranges from an Oracle table to CSV. Enhance the performance by using dbms_parallel_execute to parallelize the routine, catering to extensive data operations.

Data Export Wizard in Oracle SQL Developer

To export an Oracle table to CSV, right-click the table in Database Explorer and opt for 'Export Data'. The Data Export wizard facilitates configuring CSV format options, selecting columns, setting data types, output options, and specifying rows for export.

Exporting Query Results to CSV

For exporting query results, incorporate the /*csv*/ comment within your SQL query. Execute the query as a script with the spool command for automatic CSV file saving. Alternatively, use the GUI's 'unload' (or 'export' in newer versions) feature for a GUI-based export.

Adjustable Delimiters and Data Selection

To change the default delimiter in a CSV export, use the /*insert*/ comment. If you need to export a selected range of rows or all rows, the SQL Developer offers options to specify within the export wizard.
