Empty record sets

[Anker Berg-Sonne]

We are migrating from SQL Server to MySQL and have run into a strange problem when using ADO to access the MySQL database. If a query is "too long" or returned rows are "too long" we receive an empty recordset. I have not yet determined how many bytes "too long" is, but it is definitely associated with the length of the data.

Has anyone seen this?

Our connection string is: DRIVER={MySQL ODBC 3.51 Driver};SERVER=server;PORT=3306;DATABASE=Repository;USER=user;PASSWORD=password;

Thanks in advance/Anker
