Guest Posted: Thu Dec 16, 2004 11:41 am    Post subject: Delphi 2005 connection to MySQL, dbexpress driver error Hi to all, I am trying delphi 2005 arch on a win 2003 server machine and i would like to connect a MySQL db via dbexpress, but i can't (win32 personality). MySQL version is 4.1.7; if i use the ODBC connection (via ODBC 3.51.10 drivers) all works fine. When i try the connection via dbexpress first i set the TSQLConnection parameters and then i activate it (all works fine). After that i connect a TSQLQuery to the TSQLConnection, i set the sql statement and then, when i activate TSQLQuery, i get an access violation error on the dbexpress driver dbexpmysql.dll. If i try to use a Simpedataset or a SQLDataset component i get the dbexpress error "command out of sync". Can someone help me? Thanks in advance, Antonio. -- ------------------------------------------------------------------------ Antonio Taccone | Siamo scienziati, non ingegneri! Quote: A. A.

I will soon post the schema. I'm now working with my new delphi2005 pro version and for this reason i buyed a separate mysql dbexpress driver. Thx again and merry Christmas, Antonio. -- ------------------------------------------------------------------------ Antonio Taccone | Siamo scienziati, non ingegneri! Quote: A. A.
