Just one, actually: the object counts are 'wrong' as you pointed out once... I still didn't find a workable solution for that.

If you need a generic way to connect to several types of databases, just use simple code like this: var AConn : TSQLConnection; begin case DBType of typeFirebird : Aconn := TSQLIBConnection.Create; typeMysql40 : AConn := TMysql40Conn.Create; etc..

[Lazarus] SQLConnector
Dear all, where I can find information about how to use the SQLConnector component? Is it a general object that can be used to connect to different database types (SQLlite, Firebird, MySQL...)? I saw the property ConnectorType (string), how can I set it? Is TSQLConnector already usable? Thanks, Andrea ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
