Last Updated:Apr 01, 2026

After you enable the DAS audit log, you can use the SQL Explorer and Audit feature. The SQL Explorer and Audit features, data storage modes, and billing methods vary depending on the version of the audit log that you enable. This topic describes the differences in SQL Explorer and Audit features for different DAS audit log versions and addresses common questions about data migration between them.

What are the differences between the SQL Explorer and Audit features in different versions of DAS Enterprise Edition?

On the Version Management page of the DAS console, you can determine the DAS Enterprise Edition version of a database instance from the tab under which it is listed.

The SQL Explorer and Audit feature, data storage mode, and billing rules differ for each version of DAS Enterprise Edition.

Search, SQL Explorer, and security audit

DAS creates a task that you can track if one of the following conditions is met:

  • You query, export, or analyze historical data that is more than seven days old.

  • The query time range exceeds one day.

DAS directly queries, exports, and analyzes stored data without creating an asynchronous task.

Task list

This is a new feature.

You can view the tasks and their details created by features such as search, export, SQL Explorer, and security audit.

This feature is not available.

OpenAPI

You can call the GetDasSQLLogHotData operation to query the details of hot data from SQL Explorer and Audit for a database instance.

You can call the DescribeSQLLogRecords operation to query the log details from SQL Explorer and Audit for a database instance.

Note

After you migrate to Enterprise Edition V3, the DescribeSQLLogRecords operation is no longer supported. You can call only the GetDasSQLLogHotData operation.
