What action does SQL Developer take during the data loading process if there's an issue with data?

During the data loading process in SQL Developer, if an issue arises with the data, the tool primarily logs the issue for future review rather than automatically cancelling the entire loading session or creating an External table to display query results.

Typically, when SQL Developer encounters problematic rows, it generates a log that details the errors encountered during the loading process, which is crucial for troubleshooting and ensuring data integrity. This logging allows users to identify and rectify issues without affecting the entire session—the unproblematic data can still be loaded successfully, making it more efficient for the user.

While the creation of an External table is a valid operation within SQL Developer, it is not the primary or automatic action taken in response to data issues during a loading operation. Instead, handling problematic data through logging is a key feature that helps in maintaining an effective oversight of the data loading processes.
