RE: [PHP-DB] Query problem
you can't use COL_NAME = NULL or COL_NAME = 'NULL' and get the desired
results , you have to check for IS NULL/ IS NOT NULLSo, change the
query to
SELECT * FROM TABLE WHERE MY_FIELD IS NULL or,
SELECT * FROM TABLE WHERE MY_FIELD IS NOT NULL
>From my understanding when you check for COL_NAME = 'Null' you're actually
checking to see if your field contains a _string_ 'Null'

Assuming you run MySQL, why don't you just remove the " ' "?
SELECT * FROM MyTable WHERE MyField=NULL

Subject: [PHP-DB] Query problem
I have done this in the past, but for some reason it isn't working now
(maybe a moron). I am trying to select all of the empty or NULL fields
in a column.
This is what I have
select * from ticket where Type = 'Line' and Closeddate = ' empty space'
and have tried the following select * from ticket where Type = 'Line'
and Closeddate = 'Null' select * from ticket where Type = 'Line' and
Closeddate = 'NULL'
any clues

RE: [PHP-DB] Query problem cont'd..
ok. try this.
ahven't tested it though ...
?".$months[$x-1]."\n";
}
echo ' ';
?>
then something like (pref before the dump of months)
will be
populated when the form refreshes and then isset() will say it has a value
and drop inside to create the query. that way you avoid an expensive if or
or or or ...

Nothing jumps out at me except for the fact that you are using LIKE
without any sort of wildcard in the actual '01' string. If you don't have
a wildcard of any sort, just use = instead of LIKE
