That's right.

It's my understanding that mysqlclient.lib is the static C API library, 
and that it uses the static CRT library, and that libmysql.lib is the 
DLL import library for the MySQL C API, and that it requires the DLL CRT 
library.  It sounds to me like you want the DLL CRT library, but the 
non-DLL MySQL library.  To pull that off, you will have to rebuild all 
of the libraries involved to get the link behavior you want.  Blame

I said "nope" above, because this error has nothing to do with mixing 
CRT libraries.  You're plainly not linking to mysql++.lib.  You have to 
link to that _in addition_ to the MySQL C API library.  See the link 
settings in the example programs' projects.

Bingo.  And it won't ever be.
