Hi,
I found the following bug in sunday's snapshot (I am running Linux
2.1.85 and gcc 2.8.0):
I created a table with one column and inserted one row:
jeroenv=> create table test ( a int4 );
CREATE
jeroenv=> insert into test values ( 1 );
INSERT 321708 1
Some checks:
jeroenv=> select a from test where (a=1);
a
-
1
(1 row)
jeroenv=> select a from test where (a=1) and true;
a
-
1
(1 row)
Now, instead of column 'a' I return the constant 1:
jeroenv=> select 1 from test where (a=1);
?column?
--------
1
(1 row)
jeroenv=> select 1 from test where (a=1) and true;
?column?
--------
(0 rows)
No rows is not what I would expect.
However, with 'or' instead of 'and' returning a const value the query
works OK:
jeroenv=> select 1 from test where (a=1) or true;
?column?
--------
1
(1 row)
jeroenv=> select 1 from test where (a=1) or false;
?column?
--------
1
(1 row)
Cheers,
