ADONet appender parameter types

[hbmlists]

Hi. 

I am using log4net 1.2.9 with .Net 1.1. 

For adonet appender what should be dbtype and size for sql data type "text"? 

Also in general what are the possible values that dbtype can take and how do 
they map to Sql Server datatypes? 

Thanks,
Hemant
