Exporting an Oracle database to CSV is a common task for database administrators and developers seeking to analyze, share, or migrate data efficiently. The CSV format is widely used due to its simplicity and compatibility with spreadsheet applications and various data processing tools.
The process involves querying the database and formatting the output as CSV, which then can be saved or transferred as needed. However, complexities can arise when dealing with large datasets, custom data types, or the need for automation.
This guide will provide step-by-step instructions for exporting Oracle database contents to CSV. We will also explore how Sourcetable simplifies this process by allowing you to export your data directly into a spreadsheet-like interface in real-time.
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.
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.
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.
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.
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.
You can use Oracle's SQLcl tool to export a table to a CSV file using the CSV SQL format.
Yes, you can use the parallel hint with SQLcl or DBMS_PARALLEL_EXECUTE with either SQL or UTL_FILE to export data to a CSV file in parallel.
Yes, you can use UTL_FILE in a PL/SQL routine to export a table or a range of data from a table to a CSV file.
Yes, you can use the DBMS_CLOUD package to export data to a CSV file and save it to object storage in the cloud.
When using SQL*Plus or SQLcl, settings such as arraysize, trimspool, trimout, and flush can impact the efficiency of writing the CSV file.
