A little tip

[lucabertoncini]

This morning I needed to modify TODBCConnection in the unit odbcconn.pas. The problem was that it didn't know a field type (BLOB) retrieved from an IBM DB2 database. I simply added that when a field type is unknown it must be considered as BLOB and this trick worked well. To use this feature, I had to rebuild fpc. What about add a boolean property that lets us choose if an unknown field type must be equivalent to a blob field?

I don't think such a property would be satisfying.
The better alternative here would be a OnUnknownFieldType-Handler with a FieldType (as var) and Fieldname, and maybe some other infos.
So the programmer can choose what to do, and when.
