how are the times stored in the db ?
if they are dates or timestamps the comparison will need to be single quoted
instead of:
>My attempt, one of many,
>$result = mysql_query("select * from plant.eqpt where date_online <=
>$checkdate AND where date_offline => $checkdate order by type,
>size");
>generated the same warning.
>Still searching for a solution
try
$result = mysql_query("select * from plant.eqpt where date_online
<='".$checkdate."' AND date_offline => '".$checkdate."' order by
type,size");
you also had 2 WHERE clauses. there can be only one. like the highlander.
so if $checkdate was 2001-03-22 then the query would look like this to the
db:
select * from plant.eqpt where date_online <='2001-03-22' AND date_offline
=>'2001-03-22' order by type,size
i haven't used between on dates but it is valid SQL. good for ranges of
numbers.
