HXTT DBF
Null constraint in DBF driver

Hello,

It seems the null constraint is ignored in the DBFDriver.
I downloaded the DBF_JDBC40.jar and ran the following sql:

create table test (x varchar(10), y varchar(10) not null)
insert into test (x) values ('hello')
select * from test

Without any error.

Additionally, the driver does not report non-nullable columns, for example using squirrel-sql on the created files, the database metadata reports IS_NULLABLE=YES for each column.


Is this expected behaviour?

Regards,

Rob Gansevles

Yeah. Xbase format doesn't support not null constraint.
