Thank you for using Programmers.
To provide a better testing environment, we will be integrating the existing SQL and Database problem types.
After the integration is completed, existing SQL-type problems will be gradually deprecated following a sufficient transition and testing period. Please review the details below.
The SQL problem type will be integrated into the Database problem type.
After the migration and stabilization process is complete, existing SQL-type problems will be deprecated.
Following the integration, the problem type label will be standardized as [SQL].
April 19, 2026, 22:00: SQL → Database type integration
If you have tests configured with the existing SQL problem type, you may need to reconfigure the affected questions after the migration.
During the integration process, access to problems of the affected types may be temporarily unavailable.
Thank you for your understanding.
