mysql - Local Sql express 2 way sync to remote server -

-

i have native windows application (software) local sqlexpress database. need bring data every local install (5000 in number) central server mysql. 1./ don't think able port forwards etc on router @ every local installation , hence wonder what's best way synchronization done. 2./ @ central server should use ms sql instead. there compelling reason stick ms sql @ central level?

regards ravz

at central server should use ms sql instead

yes, , not free version.

you use sort of replication.

is there compelling reason stick ms sql @ central level?

you must joking. read documentation. sql server has nice features in non free versions - replication example. last time tried setting (laptops, ages ago) went transactional replication between sql servers , worked charm.

alternatively can sit down , start writing. there db agnostic sync fraemwork available, or can totally roll own - both valid approaches. should check first can do.

check http://msdn.microsoft.com/en-us/library/cc645993.aspx#replication

you can use transactional replication , use expres editions subscribers against central master database.

here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
