Now after I have integrated the hotfix from Thomas, I get the error
'Unsupported column type: 0' in IB_Components in
procedure TIB_Row.DefaultColumnCreation
when I try to prepare a Stored Procedure.

This only happens, if TIB_Connection.FieldEntryTypes=[fetSQLType].

I have spent nearly in Day in debugging IBO, but now I have downgraded
to IBO 4.7.16 and all works fine again.

Guido
