[PHP-DB] LEFT JOIN in UPDATE
hi...trying to circumvent the limitation of the DELETE statement only being able to use its own table...idea is to mark the records to be deleted via an UPDATE statement which allegedly accepts LEFT JOIN and then performing the DELETE statement. Question is how to properly form a LEFT JOIN using UPDATE... I tried: UPDATE product_price LEFT JOIN temp SET product_price.product_price_vdate = 1 (del flag) ON product_price.product_id = temp.product_id WHERE temp.product_id IS NOT NULL as well as some other combos...to no avail! Anyone used this know the right syntax much appreciated!!! Luis = Make it idiot-proof and someone will make a better idiot. __ Do You Yahoo!? Great stuff seeking new owners in Yahoo!

[PHP-DB] DELETE in mysql?
Thanks to those who replied...but I was hoping perhaps of a creative idea in solving the problem of deleting from multiple tables...I can't believe I will have to delete 265 records (x 3 tables) by hand... is there any other way out? I cannot install version 4 since it is on a hosted site. Thanks --- Adv. Systems Design [EMAIL PROTECTED] wrote: Maybe my example attempt is misguided but the idea is to look up the prod_id from temp to know which records to delete in the prod, prod_price, prod_cat tables, all having the prod_id field as a link...just like you can do in a SELECT statement: select p.product_id, p.product_price from product_price as p, temp as t where t.product_id = p.product_id Let me know if what I am asking is unclear. --- Rick Emery [EMAIL PROTECTED] wrote: You cannot refer to other tables.

hello all: I need to be able to update a field in MySQL, the catch is that I have to add on to text that is already there and I have to be able to do it within MySQL (phpMyAdmin).

Re: [PHP-DB] Table display Driving me Crazy!
I figured out what was wrong...and yes, the db call
was from phplib...I am making modifications to
existing code and so haven't figured out all the inns
and outs...what I did was just create an array from
the object that was being called by the query and then
addressed those array elements individually
here is a sample:
? for ($l = 1; $l = $numcols; ++$l) {
if ($int_j = $int_i){ ?
td width=139 class=ModNo
bordercolor=#00?php echo $array_sku[$int_j];
?/td
? } //endif
$int_j++;
} //endfor
...sorry if the code looks like crap but yahoo tends
to truncate the width...
thanks anyways!

method is setting an
internal member to the current record and
returning TRUE/FALSE for
success, or if it's actually supposed to be
returning a row.
It should be the former. But whatever it does, it
doesn't change the fact
that the code for displaying the 1st, 2nd and 3rd
rows are in fact
displaying a constant for each of the 5 columns.
I'm guessing the class is simply being mis-used.
The code is reasonably
logical assuming next_record() is setting an
internal member variable to
the current row... doesn't look like it is though.
If I'm not mistaken it looks to be using the phplib
library. I believe it
*is* being used correctly but he doesn't seem to be
choosing the correct
fields to display.
I know with ASP/VBScript that there's a decent
performance hit when you
jump from HTML to VbScript and back again... I
would imagine though not as
severe the same also happens in PHP. Rather than
stop the parser, print
out something small like a /td and start the
parser back up it's
probably better performance wise to just use the
'echo' function (well,
keyword, I guess echo isn't a real function, print
is though). Plus, it
makes your code more readable without all the
?php ? marks everywhere.
In this case, yes, it's preferable to use echo. But
if there are more than a
few lines of html then using echo gets tedious
pretty quickly (not mention
having to escape all the s) :)

[PHP-DB] Table display Driving me Crazy!
Hello *
trying to output mysql content into a table, but the
table is designed to use 3 Trows to display info for
ONE product (table also has to have 5 columns):
row1 sku1|sku2|sku3|sku4|sku5
row2 img1|img2|img3|img4|img5
row3 nam1|nam2|nam3|nam4|nam5
-
row4 sku6|sku7|sku8|sku9|sku10
row5 img6|img7|img8|img9|img10
row6 nam6|nam7|nam8|nam9|nam10
-
etc...
I have code that is displaying the right #of columns
but it is simply repeating the product across the
table...
table width=100% border=1 cellspacing=0
cellpadding=0 bgcolor=#00
?php
$db-query($list);
while ($db-next_record()) { ?
tr bgcolor=#66
?php $numcols = 5;
for ($l = 1; $l = $numcols; ++$l) {?
td width=139 class=ModNo
bordercolor=#00?php echo
$db-f(product_sku); ?/td
?php } ?
/tr
tr bgcolor=#ECEF7A
?php for ($l = 1; $l = $numcols; ++$l) { ?
td height=80 bordercolor=#00
div align=centerA HREF=?php
$sess-purl(URL . ?page=$flypageproduct_id= .
$db-f(product_id) . category_id= .
$db-f(category_id)); ?
?php
$ps_product-show_image($db-f(product_thumb_image),);
?/A
/div
/td
?php } ?
/tr
tr bgcolor=#C9C62D bordercolor=#C9C62D
?php for ($l = 1; $l = $numcols; ++$l) { ?
td class=prodName?php
$db-p(product_name); ?/td
?php } ?
/tr
?php } ?
/table
Anybody have any ideas how I can get this thing to
work?!
Thanks
Luis

[PHP-DB] SQL query (OT)
hi: I have 2 tables, lesson and lesson_gle, where lesson holds lesson data and lesson_gle holds repeating data that are how the lesson correlates to various state standards (one lesson can have many correlations)...one particular lesson may have a math correlation as well as a language arts correlation. From a couple of popups, I am passing numerical values for $level and $subject which pertain to a certain level (grade level) and subject (the correlations). I am decoding them using an array which I use to construct the query you see below. The query is working fine, HOWEVER, it only looks at the first correlation of a lesson...so if I ask for math, all of the lessons that have math as a second correlation are not returned, and I would like to be able to show ALL lessons that have a MA correlation. SELECT * FROM lesson, lesson_gle WHERE lesson.l_id = lesson_gle.l_id $cluster[$level] GROUP BY lesson.l_id HAVING lesson_gle.glenum LIKE '$subjaray[$subject]%' ORDER BY lesson.l_id $cluster = array ( , AND (lesson.grdlevel = '1' OR lesson.grdlevel = '2'), AND (lesson.grdlevel = '3' OR lesson.grdlevel = '4' OR lesson.grdlevel = '5'), AND (lesson.grdlevel = '6' OR lesson.grdlevel = '7' OR lesson.grdlevel = '8'), AND (lesson.grdlevel = '9' OR lesson.grdlevel = '10' OR lesson.grdlevel = '11' or lesson.grdlevel = '12')); $subjaray = array (, LA, MA, SS, SC, AT, VA, PE, TH, MU, HE, DA, FL); Thanks Luis __ Do You Yahoo!?

Re: [PHP-DB] Where do I get started?
One of the best kept secrets (apparently) is to take a program that someone else has created (preferably a mature project that has undergone some growth and cleaning) and learn what it does...syntax is just that...you will see that there are about a million ways of doing any one thing, but only certain ways (coding style) will guarantee that your projects dont collapse on their own obfuscated methods.
