HXTT ACCESS
Duplicate rows returned from select

Hi again,

I've found what I believe is another bug in the Access 3.0 driver, dated 9/17/2006. When I issue the following select:

select * from tbl_be_tax_rtn

I get one row, which is what the database contains. When I issue a more specific select:

select * from tbl_be_tax_rtn where part_ssno = '080288704'

I get not one row, but *four* rows, each with duplicate data. I've uploaded this database to your public FTP server to aid you in fixing the problem. It's called "Empty Copy of Duty Disability.mdb".

After run "reindex all on tbl_be_tax_rtn;" once,
select * from tbl_be_tax_rtn where part_ssno = '080288704'
become normal.

So that it's resulted by an invalid index.

I tested with:
insert into tbl_be_tax_rtn (part_ssno ) values ('080288705');
select * from tbl_be_tax_rtn where part_ssno = '080288705';

It's normal. I don't know what's the invalid index source of your mdb sample, which contains 4 duplicated index information for the same row.
