Delete From Database
I have code that does not delete from a database. The same code (cut an
paste in the same file, but different function and having a different query)
works. So, of course, I tested the query interactively. I echoed the query
and did a cut and paste when interactively connect to the database. That
one worked so it isn't the query since interactively it is seeing exactly
the same thing as the code produces.

Here is the code:

function deleteCatalog($catalog) {
$query = "DELETE FROM CatalogNames WHERE sCatalogID='" . $catalog . "'";
mssql_select_db($database_Login, $_SESSION['Login']);
$result = mssql_query($query, $Login);
...
}

The $query echos:
DELETE FROM CatalogNames WHERE sCatalogID='CMP'

As an example of code that works (in the same file)
function addToCatalog($cat_id, $cat_name) {
$query = "INSERT INTO CatalogNames (sCatalogID, sCatalogName) " .
"VALUES ('" . $cat_id . "', '" . $cat_name . "')";
mssql_select_db($database_Login, $_SESSION['Login']);
$result = mssql_query($query, $_SESSION['Login']);
...
}

The second and third lines are identical (cut and pasted) as in other places
in the same code. In fact, it is only in this file that I do all the
database work. Every other function works. This is the only delete,
however.

Delete MySQL Data
I am building a lunch ordering system for a company. The employees can login, order lunch, and the administrator can see what everyone ordered for lunch in the admin panel. The problem is that when the employees enter data, it stays in the database until they update it. If an employee is sick, their lunch order from the previous day is still in the database. Is there a way to clear those values they enter at a certain time in MySQL.

How To Delete MySQL Database.
I've got three hostings with the GoDaddy hosting service. The hostings are supposed to provide only one MySQL database each. I've just recently noticed in the phpMyAdmin program that separate databases, each with the name "test," has appeared in two of the three hostings.

I don't know how they got there. I didn't put them there. I contacted GoDaddy's technical support. They said that the "test" databases automatically comes with the phpMyAdmin program. Of course, that's not right. Anyway they said that I could delete the extra database without damaging anything.

Comparing Database Data And New Data
I am trying to create a PHP script that reads in a file, parses it for the data I want and compares it to the data I have in a database.

The data is points and ranking information for a Folding@Home Team.  Every week someone creates a news item with points gained by each team member for that week and other info.  This is done manually and takes a lot of time.  I hope for my script to automate as much of it as possible.

The script was to run as follows:

Download and parse latest statistics into 2D array
Compare usernames in array to usernames held in Database
Any new usernames and their respective points/rank to be added to database

Compare points in 2D array of each user to those held in database.
Output username and points gained

I thought I had a working script until I actually tested it on real data, and realised I missed something rather obvious - the order of usernames from the parsed file is not going to be the same order as in my database - due to people moving up and down the ranks.  So i can't just get a recordset from the db and run a simple loop to compare it to the parsed data.

I am not sure how to go about comparing the database information with the parsed data that works around the fact the data could be in any order.  The only thing i can think of is:

foreach item in $parsed_data_array
    query database for $parsed_data_array=>username
        if(number of results == 0)
          build new insert query for current username
        else
          continue

I don't know if this works [haven't tested yet] but I can't help feel it is a little DB intensive.  There could be up to 200 queries being sent to the database.  This can be minimized by adding extra criteria, like ignoring inactive users of course.  Is this a viable solution or is there a much better way of doing this?

Product 2  <----I want this one as well
Product 3  <----i want this one too
Product 4
