Hi,
I experience a strange error with 7.0.2. I cannot get any results with
certain queries. For example, a foo table is defined with a few columns,
it has a
id_string varchar(100)
column, too. I filling this table, it contains e.g. a row with
'something' in the column id_string. I give the next query:
> select * from foo where id_string = 'something';
I get no result.
> select * from foo where id_string like '%something';
I get the row. Strange. Then, if I try to check the result:
> select substr(id_string,1,1) from foo where id_string like '%something';
now I will get 's' as expected... Dumping the database out and bringing it
back the problem doesn't appear anymore... for a while... I cannot give
an exact report, but usually this bug occurs when I stop the database
and I start it again.
Did anybody experience such a behaviour?
TIA, Zoltan
Kov\'acs, Zolt\'an
