From: Date: August 2 2004 4:04pm Subject: WinXP MSACCESS migration to -> MySQL -ODBC extremly slow List-Archive: http://lists.mysql.com/win32/15296 Message-Id: <410E49E8.2020202@aon.at> MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit I`ve migrated from MS Access to MySQL using VC++ 6.0 and MyODBC. But a select * from a join of 3 Tables takes about 6 sec. compared to <1sec using MS Access. (All SQL ODBC statements are the same as used for the Access version, database tabeles were copied 1:1 ) Im working on a single PC as local admin. steps done: - using snapshot instead of dynaset (to avoid a total crash) - switches set in ODBC driver: ( MySQL ODBC 3.51 Driver DSN ) X) "Donīt use set locale" - was mentioned in this list, but doesnt help _) all other switches not set ! Version: mySQL 4.0.20a-nt, Port 3306 DLL used: myodbc3.dll (not the debug version) Any idea ? thx , Roland
