First of all thank you for this information!!!

I'm using MySQL/C#/Crystal Reports. After setting up the ODBC/DSN something as simple as this worked for me.

using CrystalDecisions.CrystalReports.Engine;

using MySql.Data.MySqlClient;

.

ConnectionInfo connInfo = new ConnectionInfo();

connInfo.ServerName = "Driver={MySQL ODBC 3.51 Driver};DSN=MyODBCDatasourceName";

TableLogOnInfo tableLogOnInfo = new TableLogOnInfo();

tableLogOnInfo.ConnectionInfo = connInfo;

// rpt is my Crystal Reports ReportDocument

// Apply the schema name to the table's location

foreach (Table table in rpt.Database.Tables)

{

    table.ApplyLogOnInfo(tableLogOnInfo);

    table.Location = table.Location;

}
