Fixed issues

• Database objects

  • In OceanBase Database in MySQL compatible mode, the window gets stuck if you do not have the permission to access table schemas.

  • The SQL statement generated when you rename a constraint is empty.

• Execution of PL\SQL statements

  • After the execution of PL\SQL statements times out, no error message is returned and reconnection is not automatically prompted.

  • In some cases, the execution of PL\SQL statements leads to the report of a null pointer exception.

  • Parameters whose values are set to NULL or default cannot be recognized during the PL debugging.

• Import and export

  • The database connection cannot be released in some import and export tasks.

  • An error occurs in the result set when you export the DATETIME type.

  • The exported result set cannot be desensitized.

• Database changes

  • Data of the YEAR and DATETIME types is incorrectly displayed in a database change task.

  • The rollback step of a scheduled database change task may not be executed.

  • The following error may be returned when you query the execution result of a scheduled database change task: query result file not found.

  • The downloaded query results of a database change task before and after the rollback are inconsistent.

• Connection management

  • The connection cannot be created due to the failure of the connectivity test in some cases.

  • You can connect OceanBase Database in MySQL compatible mode to native MySQL Database, but an error message is returned.

• Partitioning plans

  • When you create a partitioning plan, deleted partitioned tables may be displayed in the scan results.

• Collaborative control

  • In multi-node deployment mode, OceanBase Developer Center (ODC) sometimes cannot synchronize with the status of external approval integration.

  • The error message indicating that a connection does not have the corresponding approval process is not available in multiple languages.

  • An error is returned for the verification of read and write permissions on a public connection.

• Other modules

  • When ODC forwards a request in multi-node deployment mode, it may lead to a recursive call.

  • If an object has special characters in its name, it cannot be restored from the recycle bin.

Known issues

• The floating-point precision is lost when exporting Float data.

• The Client ODC cannot be installed in a directory whose name contains Chinese characters.

• The exported data file and content are incorrectly displayed when the table contains virtual columns.

• The SQL statement generated is incorrect because not all primary partition keys are included in the global unique index.

• In web ODC, the maximum size of schema or data imported in a batch cannot exceed 2 GB, and files that exceed the limit cannot be uploaded.

• In web ODC, the maximum size of schema or data exported in a batch cannot exceed 2 GB. Exceeding the limit will cause the final export data to be incomplete.

• OceanBase Database Enterprise Version V4.0.0 and OceanBase Database Community Edition V4.0.0 do not support data import or export.

• In the details of an export task, the total number of data records of the exported object depends on the views of OceanBase Database and is not an accurate value.

• The ob_enable_trace_log parameter must be set to on. Otherwise, only the execution plan of the first executed SQL statement will be displayed.
