DBX Error: Error Code: 65535.

Post by sstewart » Mon 17 Aug 2009 10:37

Hello,

Our application is a multi-threaded server application, which is quite mature at this stage. It is installed on many customer sites and we support several database types, including Oracle, MySql, DB2 and MSSQL.

Recently we have started seeing this error message appear: "DBX Error: Error Code: 65535." while connected to SQL Server using dbexpsda40.dll (4.25.0.8 ). It appears to happen randomly or at least we have not noticed any obvious pattern.

Does anyone know what this error means?

Thanks,

Steve

I can not reproduce the problem and we have not encountered such problems before with other users.

I see the same error message in my log this morning. I use dbexpmda40.dll and libmysql.dll from 5.0 MySQL server.

Our application is a multi-threaded server application too­.

In order to solve the problem try to use the Direct mode to connect to MySQL database. DbxMda provides direct access to database, doesn't require MySQL client installed and that increases performance. For this you should set the TSQLConnection.DriverName property to 'DevartMySQLDirect' and the TSQLConnection.GetDriverFunc property to 'getSQLDriverMySQLDirect' value.
