IMPORT FROM JDBC: Allow sources without JDBC Connection.rollback() method

Detail name	Value
Changelog Number	13751
Type	Improvement
Status	Resolved
Fix Versions	Exasol 8.0.0, Exasol 7.1.7
Resolution Date	2022-03-16

Background

At the end of each IMPORT FROM JDBC statement, Exasol calls the JDBC Connection.rollback() method before closing the connection to the data source to ensure that no persistent changes are made in the data source.

If JDBC Connection.rollback() method is not implemented for the specified driver, it will raise an exception causing the IMPORT to fail.

Improvement

IMPORT FROM JDBC supports sources where JDBC Connection.rollback() is not implemented.
