Question

I have a boolean (BOOL) type field in the SQLite table.
In the SubSonic generated DAL it is represented as string (instead of bool).
It is weird.
How it can be managed? Please, help.

I maybe wrong on this, I have only used Subsonic 2.2 with SQL2008 but I would recommend looking at the source for Subsonic, namely SQLLiteDataProvider.cs and reviewing the DbType function.

It seems to recognise the type Boolean but not Bool and the default when it does not recognise your type is to resort to String.

Hare is the code in question from that function

 switch(sqliteType.ToLowerInvariant())
            {
                case "text":
                case "char":
                case "nchar":
                case "varchar":
                case "nvarchar":
                    return DbType.String;
                case "boolean":
                case "bit":
                    return DbType.Boolean;
                case "bigint":
                case "int":
                case "integer":
                    return DbType.Int64;
                case "real":
                case "numeric":
                case "double":
                case "single":
                case "float":
                    return DbType.Single;
                case "smallint":
                    return DbType.Int16;
                case "date":
                case "time":
                case "datetime":
                case "smalldatetime":
                case "timestamp":
                    return DbType.DateTime;
                case "binary":
                case "blob":
                case "image":
                    return DbType.Binary;
                case "guid":
                    return DbType.Guid;
                default:
                    return DbType.String;
            }

I would recommend changing it, seeing if it works and then recommeding the change to the subsonic chaps.
