SHOW ENGINE INNOD Problem: The purpose of explain_filename() is to provide useful additional information regarding the partitions given the filename. This function was returning an error when it was not able to parse the given filename. For example, within InnoDB, temporary files are created with #sql- prefix. But this function was not able to parse it correctly. Solution: It is not an error, if explain_filename() could not parse the given filename. If there is no partition information to explain, then silently return from the function. rb#1940 approved by mattiasj
