Hi,
I think your problem is that OR and AND do not
have the same precedence, AND binds tighter.
So what you need is probably:
(products_model=5217-01 OR products_model=5217-01) AND
products_um=CS and the same for PK and EA.
The way you have you'll get an update as soon as
products_model=5217-01

I believe that should work.
As a precaution, I recommend always using LIMIT x whenever possible on

You should try it. It works just fine, and isn't the problem. The
problem is that you cannot treat the result of an UPDATE as if it were a

Thanks Peter,
I didn't know that MySQL has no UPDATE ... SELECT command.
I followed your advice and made the following query
UPDATE Data AS db INNER JOIN
(SELECT myKey,Year,
SUM(IF(Month= 1,Cell,Null)) AS `Jan`,
...
SUM(IF(Month=12,Cell,Null)) AS `Dec`
FROM Updates GROUP BY myKey, Year
Updates
to 1 Data record where MyKey and Year are equal.
I tried the following query:
UPDATE Data AS db INNER JOIN Updates AS U
ON db.myKey = U.myKey
SET db.Jan = IF(U.Month = 1, U.Value, db.Jan),
db.Feb = IF(U.Month = 2, U.Value, db.Feb),
...
db.Dec = IF(U.Month=12, U.Value,db.Dec
,
but no UPDATE ... SELECT command, so this will be a two-step. If I
understand your
description correctly, you want to aggregate by month and report by
mykey and year, so
your crosstab would look something like this (not tested)...
CREATE TEMPORARY TABLE crosstab
SELECT
d.myKey,
d.year,
SUM

Hi,
In your query you try to update on the condition column 1 = number2 and

I think what you want is column 1 = number2 or column1 = number3 .
If you use and it will try and found a record in column which has a value =

To those thinking of answering this question, There is additional

For some reason, I found out that the version of PHPMyAdmin at my web
hosting provider was missing the Insert data from a text file into the
table feature found at the bottom of the page after clicking on the

Mike,
The documentation at
http://dev.mysql.com/doc/refman/5.0/en/update.html explains that MySQL
is aware of the fact that it only needs to update different values --
for instance, it returns only the # of rows changed, not the # of rows
looked at. Given that, I will extrapolate that MySQL
