Thank you... That is very helpful about the wrong db driver. The on-line running script is using mysql mariadb. I am using mysql workbench on the localhost. I doubt very much that it has anything to do with script or the data. Can anyone give me a hint how to change the driver? I have no idea. Thanks again!
