try this:

CREATE DOMAIN BASENAZWANULL AS
VARCHAR(100) CHARACTER SET WIN1250
DEFAULT NULL
COLLATE PXW_PLK;

CREATE TABLE TEST (
ID INTEGER NOT NULL,
TEST BASENAZWANULL DEFAULT null
);

...then put on a form simple TZQuery, set it's SQL to "select * from TEST"and connect a dbGRid to it and try to insert a record but leave field TEST empty and post.

I'm getting this:

"Token unknown (..) DEFAULT (...) Invalid token The SQL: SELECT DEFAULT NULL FROM RDB$DATABASE"

That "SELCT DEFAULT NULL" is obviously wrong syntax - it seems ZEOS get's confused if DEFAULT NULL is used both in DOMAIN and in table's field definition.

Any quick fix or a remark where to do the fix?

Cheers,
Tomasz

Hi Tomasz,

I suppose it shouldn't be to difficult to fix this thing but I'm not using firebird so it will be somebody else's job. I think a quick source search for RDB$DATABASE in all source files with 'Interbase' in the name will give you a hint about where to start.

Mark,

Thanks for the reply, I'll register a bug. I think I've also found another one in the Firebird dbc - and I register it there as well

Cheers
