MySQL ODBC 32 vs 64 bits

Question

J'ai une application 32 bits qui doit fonctionner sur un serveur Windows x64 en utilisant une version 64 bits de MySQL.
Dois-je utiliser un pilote ODBC 32 bits ou un pilote ODBC 64 bits?
Ou devrais-je également installer une version 32 bits de MySQL?

Answer 1

j'ai pu

1. installer ODBC 32 bits sur Windows 64 bits

2. ma demande d'inscription (32 bits) en cours d'exécution bien avec ODBC 32 bits " contre » 64 bits MySQL sur Windows 64 bits OS (R2 2008)

Pour réaliser 1) j'ai dû modifier install.bat fourni avec le paquet zip de MySQL ODBC pour prendre en compte le fait que le pilote 32 bits doit être installé en c:\windows\syswow64.

Answer 2

Vous devez installer un pilote SQL et ODBC 32 bits vu que votre application est en 32 bits. Pour des raisons de compatibilité.

Je suis toujours en train de chercher, je vais modifier.

** EDIT

Pour contourner ce problème, utilisez la version appropriée de l'outil Administrateur ODBC. Si vous générez puis exécutez une application en tant qu'application 32 bits sur un système d'exploitation 64 bits, vous devez créer la source de données ODBC à l'aide de l'outil Administrateur ODBC dans% windir% \ SysWOW64 \ odbcad32.exe. Pour indiquer le type de DSN, vous pouvez ajouter "_32" aux DSN utilisateur 32 bits et "_64" aux DSN utilisateur 64 bits.

De Microsoft support.

** EDIT

Si vous voulez avoir une solution de contournement, vous devez vous créer source de données ODBC à l'aide de l'outil Admin trouvé dans. Ceci est expliqué également dans le même lien.

%windir%\SysWOW64\odbcad32.exe
