The Brief
The Client’s mystery shopping programme consists of visits to each of the client’s ten locations, grouped into five different areas. Each location receives a single visit each month, but on occasion a visit may not take place.
On the completion of each visit, a questionnaire is completed by the mystery shopper that is used to rate the service they received during the visit. The completed questionnaire is assigned a score, which is calculated based on the number of points achieved over the number of points available, normally expressed as a percentage.
Points Achieved x 100 Points Available
= % Score

I need help with this. I had a dream… Well, not so much as a dream, maybe a “It’d be cool to…”

I thought it’d be nice to discover new photos on flickr using your favorite photos and the people who also favorited those photos, and the favorite photos of those who also favorited my pictures. Still with me?

It’s actually a quite simple code (about 500 lines, check it on github: discovr), but it’s terribly slow. Some possible reasons:

• Way too much data. I’ve found people with around more than 18000 favorites, and there are photos with

I had a sad time this year when I missed the MySQL conference, since I had much fun last year in Santa Clara. I can’t miss it next year.

As a MySQL partner, and after almost 2 years doing MySQL training, I sure have interesting things to tell in the conference, but I’m not sure about what.

I will be thinking about this in the next weeks, but I’d appreciate some help. What topics are you interested in?

Slave delay can be a nightmare. I battle it every day and know plenty of people who curse the serialization problem of replication. For those who are not familiar with it, replication on MySQL slaves runs commands in series – one by one, while the master may run them in parallel. This fact usually causes bottlenecks. Consider these 2 examples:

• Between 1 and 100 UPDATE queries are constantly running on the master in parallel. If the slave IO is only fast enough to handle 50 of them without lagging, as soon as 51 start running, the slaves starts to lag.
• A more common problem is when one query takes an hour to run (let's say, it's an UPDATE with a big WHERE clause that doesn't use an index). In this case, the query runs on the master for an

I tend to use MySQL from the interactive command line shell quite a bit (SSH to your db server and type the command mysql to start). I noticed today that there is a pretty extensive built in help system in this command.

You can access it by typing help COMMAND, so for instance if you type help ALTER TABLE you get a quick reference for constructing an ALTER TABLE statement.

If you can't remember what command you want to use, then typing help contents is your friend. It will output:

For more information, type 'help item', where item is
one of the following categories:
Administration
Column Types
Data Definition
Data Manipulation
Functions
Geographic features
Transactions

So if your looking for that command that outputs all the columns in a table, but don't know what it's called, you
