Hi Zoltan I have had same problem... Try to insert guid as char, don’t convert to guid. INSERT INTO T(G) VALUES('12345678-1234-1234-1234-123456789ABC');
>INSERT INTO T(G) VALUES(CHAR_TO_UUID('12345678-1234-1234-1234-123456789ABC')); >SELECT UUID_TO_CHAR(G) FROM T; >Result: '12345678-1234-1234-1234-123456789ABC' >Result by FB.NET client SELECT G FROM T: (FB.NET handles CHAR(16) OCTETS as >Guid) >'56781234-1234-1234-3412-34127856BC9A' [PM] as you can se...my problem is the same if I convert to uuid: String from Membership: d1f5d194-5fa8-4ba1-bcf5-a4a788b58c1a String from database: D194D1F5-5FA8-4BA1-F5BC-A7A4B5881A8C As Jiri said: Look like Guid in .NET has little bit different text representation than uuid_to_char from Firebird. Quaternions are swapped. BTW I think, that you should compare not strings but the guid values as bytes/octets directly.
