Update With If Statement
I'm trying a statement which I cannot figure out what I'm doing wrong on. I've tried every combination that I can think of and stared myself blue with no success.

update cdr set Cost=if(mod(BillSec,6)=0,int(BillSec/6),int(BillSec/6)+1)

The idea is to update Cost with a value depending on the result of a formula. It's an empty field which gets a computed value from other fields. cdr is the table.

UPDATE / JOIN STATEMENT
i have problems after updating mysql from 4.x to 5.0.19. This statement should update about 3000 rows but it only does 15 but there are definitely another 2000 rows with an older date and matching nr!

UPDATE tab1,tab2
SET tab2.newdate = NOW()
WHERE tab1.nr=tab2.nr;

I tried the variation with inner joining tab1 as well. same result.

Conditional Update Statement
I have a table with a field of ID numbers. I want to update this field and replace the ID numbers. For example I want every record that currently has the ID number 2,5,6,or 9 to be replaced with a 1. Every record with 1 or 4 to be replaced with 2 ...

I can't seem to form the update statement to do this. I can do them one at a time but this won't work because if I change 2,5,6, and 9 to 1 then when I run then update for 1 and 4 it will change them all. Does this make any sense?

I want some way to be able to use a condition...if id=2 or 4 or 6 set it to 1 and if id= 1 or 4 set it to 2.

My failed attempt:

mysql> update client_software set software_id=1
WHERE (software_id=2 or software_id=5 or software_id=6 or software_id=9)
AND software_id=2 WHERE (software_id=3 or software_id=7 or software_id=8)

CASE Statement In Update Command
I'm trying to update one table (tbl_usage) based on information from another table (tbl_subscriptions) joined by the userID. The usage table tracks the number of times a user hits a page, and decrements the count each time. When the user has a zero count, they are redirected to a warning page.

Each week the count is reset depending on what type of license they have (licenseType) and how many of those licenses they've bought (numLicenses). A group license (G) gives them 100 hits, and an individual license (I) gives them 5 hits.

I'm trying to use a case statement to perform this count reset operation, but I can't seem to get it to work. The following case statement works just fine: Code:

Update Statement :: Data From One Table To Other
I have two tables, and I want to take data from one table, and overwrite it onto the second. Unfortunately, my SQL is pretty weak.

The first table has a mediumtext column and a id (primary key) column. The second has an id (the same as the first), a number, and a mediumtext column.

I want to take the contents of the mediumtext field with the highest number and replace the contents of the field in the first column with it with the same id.

My instinct is to do it this way:

update forum1post p
set p.pagetext = (select query1.message
from (select pe.message, max(pe.editnum)
from forum1post_edits pe
group by p.postid) query1)
where p.pagetext = 'Why did you all flame my topic. Screw your ****ing forums.'
and p.postid = pe.postid

However, that does not work, as pe is not recognized.

Help With Simple SQL Statement To Update Zipcodes
I have a varchar(5) field in a database called 'zip_code'. I imported some zipcodes from an Excel spreadsheet, but the spreadsheet had truncated any zipcode that started with a "0" and removed the zero, so the correct zipcode of "08993" was incorrectly placed into the record as "8993".

Would someone help me write a SQL statement to run on the field zip_code that would look at the data, if it was four characters long, add a "0" to the start and keep the remaining four characters in place?

When Is A Query Too Long?
I'm just curious to other opinions on the whether you should start to break the sql query in question up, into 2 queries maybe?

I have the problem at the moment where I am pulling data from 5 different tables, subqueries and all! I am just not entirely happy with the size of the query and wanted to hear other opinions, Do you try to simplify the query by breaking it up?

All tables are normailised (to the best of my ability) and index accrodingly so all that is ok, I am just curious to hear anybody else's thoughts on this.

Long Queries Priority
I have a 120M record table that needs to have indexes added as a
background process. While running the CREATE INDEX command, which is
taking several days, all other SELECT queries on the same machine (on a
different database) are slowed dramatically.
Is there a way to reduce the CREATE INDEX priority so that other SELECT
queries can still function at normal speed?
The OS is linux, and I have tried to 'nice' the caller script, which
works for shorter queries, but presumably the longer queries are
running entirely in the MySQL process that isn't 'nice'.

MySQL Taking Too Long
I'm trying to run a php script written by someone else, not me, and it's
getting stuck in a particular step. Actually it isn't getting stuck per se,
but the browser is, because it's taking forever to return the results back
to the browser.
Here's the line that's responsible for this:

$users = $db->query_return_array("SELECT * FROM user");

It's getting stuck because in my database I have over 60,000 records. Now,
I'm just wanting to get over this step (it's an upgrade script), not looking
for fancy proper methods of php coding.
What alternative ways are there for me to prevent the browser from timing
out? I'm guessing some way of looping through the records, and updating the
client with simple update characters to prevent it from timing out.
