Use limit in your select statement.

[PHP-DB] Re: SQL WHERE datetime NOW
John Dillon [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] ...WHERE TO_DAYS(NOW())+1TO_DAYS(MyTable.MyField) ORDER BY MyTable.MyField DESC LIMIT 30; however, the LIMIT seems to apply before the ORDER BY clause. How can I get the LIMIT to apply after the ORDER BY? On further reading, it appears LIMIT stops the query running once x number of records are retrieved without sorting the whole table first. Is there a function to get the top x number of results, as there is in MS Access? Eg search on an auto-increment and get the last 10 records added? (They don't always appear at the end of the table, I think if I am editing the table they can appear after the currently active record.)

Where did you read this? If you profile your query you'll notice that in say a 10,000 record table, if you LIMIT 0,50 but order by something generic (say an ID or date stamp) it'll still order all 10,000 records before returning the 50 you asked for.

Where did you read this? http://www.mysql.com/doc/en/LIMIT_optimisation.html If you use LIMIT row_count with ORDER BY, MySQL will end the sorting as soon as it has found the first row_count lines instead of sorting the whole table.

Eg search on an auto-increment and get the last 10 records added? LIMIT 50,-1 Retrieve from row 50 to last. I meant to largest 10 values in a column. For example, I have a record with ID number 1800 in an auto increment field, table has 1805 records. When I view the table 'raw' record 1800 appears after record 12. I wanted records 1755-1805. Instead now I've retrieved the whole table with ORDER BY without LIMIT and put my start and end values in the for () loop. Now, my eyes may have deceived me...

menu into mysql database but encountered some problem here. Values in the drop
down menu are retrieved from DB as follows:

$sql = mysql_query(SELECT DISTINCT tutor_name FROM tutor);
while ($row = mysql_fetch_array($sql))
{
print OPTION VALUE=\$tutor_name\ .$row[tutor_name]. /option;
}
$result = $db-query($sql);
?
/SELECT
/SNIP
---
echo $_POST[tutor_name];
INSERT statement:
$sql = INSERT INTO class (class_code, tutor_name, edu_level, timetable_day,
timetable_time)
VALUES
('$class_code','$tutor_name','$edu_level','$timetable_day','$timetable_time');
---
I am trying to POST the values and then INSERT into DB but was not able to do
so(all other values eg. class_code, edu_level etc...was able to be
INSERTED into DB but not tutor_name. So, how do i insert values into DB from
a dynamic drop down and where have i gone wrong???Hope to get some help real
soon.=)
