RE: [PHP-DB] Select where date is in period
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.

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.

The database has a table of equipments with date fields for
date_online and date_offline.
The requirement is to find which equipments were available on a date
specified by the user, this being a variable created by the user.
My attempts at scripting for the condition where the date_online =
'specified variable' and the date_offline = 'specified variable'
totally fail for syntax says mySQL (and possibly for method)
___Richard___
Have you checked at the BETWEEN (x and y) clause?
e.g.
SELECT * FROM table WHERE searchdate BETWEEN (date_online AND
date_offline)
Not tested this on MySQL, but the above is perfectly legal SQL92.

Thanks for that. I searched the Manual, yet again and could not find
this or like syntax. I tried it though and got
Warning: Supplied argument is not a valid MySQL result resource.
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.

Sorry. Careless as usual. The variable $checkdate was enclosed in
single quotes as
$result = mysql_query("select * from plant.eqpt where date_online =
'$checkdate' '$checkdate' = date_offline order by type, size");
