mysql run-time error (80040e21) Multiple-step OLE DB operation

[Miguel Jimeno]

I'm working with Visual Basic 6 connected to a MySQL 4.1 using this connection string:
"DRIVER={MySQL ODBC 3.51 Driver};SERVER=server; DATABASE=re;UID=root;PWD=a;"
Then I make a simple select, like this:
SQL = "Select Name, Title, ... from Products where Active='" & con & "' order by Name"
rs.Open SQL, basedatos
where:
Public basedatos As ADODB.Connection
Public rs As ADODB.Recordset
And I get this error:
mysql run-time error (80040e21) Multiple-step OLE DB operation. Check each OLE DB status value, if available. No work was done.
Any idea how to solve it?
Thanx, M
