I have this query below:
$msgg = mysql_query("SELECT *
FROM mytable
WHERE time>$time
AND id='someid'
ORDER BY id ASC
LIMIT $display_num",$myconn);
see this line: AND id='someid' <-- someid ...
OK, the query above returns 2 results as expected...
Now for the problem....
-- I have a variable myVar and it's content is " someid " (without quotes)...same as the string ' someid '
When I do this:
$msgg = mysql_query("SELECT *
FROM mytable
WHERE time>$time
AND id=myVar
ORDER BY id ASC
LIMIT $display_num",$myconn);
See: myVar <-- this variable contans .. someid
The second query returns no results.
Update: When using ... AND id='$myVar'
it sees $myVar
as empty for some reason.
Put a $ in front of myVar:
$msgg = mysql_query(
"SELECT *
FROM mytable
WHERE time > $time
AND id = '$myVar'
ORDER BY id ASC
LIMIT $display_num", $myconn
);
You forgot the dollar sign and the single quotations:
AND id='$myVar'
Additionally, you may want to consider using heredoc :
$query = <<<MYSQL
SELECT *
FROM mytable
WHERE time>$time
AND id='$myVar'
ORDER BY id ASC
LIMIT $display_num
MYSQL;
$msgg = mysql_query($query, $myconn);
