Also: I disagree with the poster above, this will return 0 rows.

Draw a table on a piece of paper and in the first column randomly write a number in each row but be sure to include the numbers...

Remove your 'or' then union the entire query with same except perform the join on r.fk_user_to=u.user_id:
SELECT * FROM (
SELECT r.fk_user_to,r.fk_user_from,u.user_first_name, u.user_last_name,...

ahh, then consider you have x number of inputs (42 in total), your loop now reads:
for ( i = 0 ; i <= x ; i++){
var tempVar = m[i];
}

The crucial bit is where x gets to the length of the array...

It's also worth noting, given the request regarding efficiency, that you should order your IN clause by the whichever value is most likely to occur in the database most often, i.e. if there are...

document.Italy is so messy.

At the least use document.all.Italy

Better still would be to give the element an id, thus: <form action="/World-Cup-2010-Country-Italy" name="Italy" id="Italy"...

Your three 'HINTS' suggest this is a uni/college coursework, lol

Can you show any of your html, or is it dynamically created?

i <= m.length - a short discussion...

if there are no <input> elements on the page then the code will still run through as i is...

Yip, it has to run the conversion on every line on the table, whether it's selected or not - a huge overhead.

You would only need one table for all loggers, with a unique id to, erm, identify them with. This would then have a one-to-many relationship with the table described above (svidgen's post).

You...

For something like that, you'd use WHERE clauses, eg.

SELECT <rows>
FROM <table>
WHERE id BETWEEN 57 AND 66;

or

SELECT <rows>
FROM <table>

I'm assuming you're wanting this to allow for IE's different JavaScript capabilities?

You used to be able to do this:

browserAgent = navigator.userAgent;
browserIE =...

SELECT SUM(points)
FROM 'table'
WHERE game = 'pingpong';

SELECT CL_WSP_NAME,CL_PROJ_NAME,CL_ORGANIZATION_NAME,CL_MAPID,SUM(MAPPED_CNT) MAPPED, SUM(NOTMAPPED_CNT) UNMAPPED,MAX(CL_MAPRUN_DATE) CL_MAPRUN_DATE,CL_CONFIRMER_ID,CL_VENDOR_FILE,CL_MAP_COMMENTS,...

Questions?

Where?

I just copied the one line and edited it.

Kind of thought that was obvious. Evidently it was not :(

for(var i=0;i<group.snapshotItem.length;i++){

<script type="text/javascript">
function formDisplay(shaftOpVal) {
if(shaftOpVal=='default' || shaftOpVal=='hollow') document.getElementById("hidediv").style.display = "block";

getDate() returns both the time and the date.

The select should take care of the ordering of display data...

SELECT *
FROM locations
ORDER BY location_id/location_name/whatever/etc

Quarter past three

SELECT account, Count(reviewer) revCount FROM

Sorry, I tested using Oracle 10g.

This should work (I think):

These should order the data for you as well.

Let me know if it works.

SELECT account, Count(reviewer) FROM
USER left join
(SELECT reviewer FROM table1
UNION ALL
SELECT reviewer FROM table2
UNION ALL
SELECT reviewer FROM table3)
on account = reviewer
