[Mysqlcppapi-main] why simple1.cc doesn't catch exception correctly

[Liu, Y. <Yig...@an...>]

Hi there,

I still have the problem with example simple1.cc.=20

In original simple1.cc code, it connect to a local server. Locally, I
didn't run mysql database daemon/server because of other reason. So when
I run simple1, it should fail to connect and throw some exception, which
should be caught by one of the "catch" statements ( and I added
catch(...) which suppose to catch all uncaught exceptions ) and exit
gracely. However, it always crashes. Does mysqlcppapi throw exceptions
when it cannot connect to mysql server?

Thanks

Yigong

Hello again,

I'll take a look at your problems when I get home in a couple of hours.
Sorry for the delay,
