In other words, the LGPL lets you link proprietary code with the library, while the MySQL exception only lets you link other FOSS code with the library. The MySQL library remains under the GPL and you cannot link that with proprietary code.
That's my reading of the exception, I'm open to correction if I've got it grossly wrong.
Its bit more complicated then that. This exception opens up the possibility to use BSD license. Which enables software to be shipped without having to distribute code.
Way to go about doing this is to have a wrapper around client library which is BSD. This wrapper can be distributed without having to open up rest of package.
