This is a cheat sheet that I have put together for keeping track of the results of ordering different types of columns in ASC and DESC order and the rules around each. This order is fairly standard for most ANSI database servers. However I do not believe that there is anything in the ANSI spec that dictates this as a requirement.
Everyone says that real estate is all about location, location, location. And I agree completely! But the real reasoning is a little different than you might think. I live on a little road called Ridge rd. Does not seem like there should be anything wrong with that, until you have to give that address to a deliver person.
I created a small simple bot in python to download the updated GeoNames daily updated files to be processed by the database. These files are generated each day and remove the need to load a full 2GB dataset into the database to keep the database updated.
Rounding is the representation of a number in a shorter, simpler or more explicit way. Its intended purpose is to replace any number with a shorter representation of it. It is important to remember that you are manipulating that number and what that manipulated representation is meant to convey. The root of the issue is simple. When you round a number, you are changing the number.
INSERT IGNORE is used in our organization to insert new records and ignore records that have the same primary key. This ignores the duplicate key exception that is generated and simply throws away the record. This allows for inserting those records to not make without having to employ a LEFT JOIN to avoid the duplication. Continue reading MySQL INSERT IGNORE
We usually use JOIN to find the intersection between two different tables. For example, if you want all the orders from the order table who belong to a certain set of customers from the customer table.
This is the most common usage of a JOIN, specifically an INNER JOIN. The results only include the entries that matchup from each table. There are many other situations that you can incorporate a JOIN to solve. Particularly here we are going to talk about using a JOIN to suppress information from one table by using another.

I have been riding on two wheels for the past twenty years now. I have definitely noticed a rapid increase in the number of motorcycles out on the road with people who do not have a clue as to what they are doing. I don’t claim to be an expert but I have had a lot of things happen and a lot of things go wrong while I was on my bike. So this is my list of essential items that go with me when I’m out on my bike.

The trip finally was able to happen after all the planning from Part 1. On Saturday April 26th, 2014 Dad, Debora and I were able to drive into Boston to take the Downeaster Amtrak train from North Station in Boston to Freeport ME.

The Downeaster Amtrak train has service from North Station in Boston all the way to Brunswick Maine! I was able to talk my wife, Debora, and my father in to a train ride up to Freeport Maine for a day of shopping and eating (it was the eating that talked Debora into it!)

Our wedding seemed like a great first post on the new fresh site. I put a lot of this on Facebook, but I think that it will be great to go through the entire trip for anyone interested in our 4 day Vegas marathon trip. The small hand drawn images throughout the post are the small pictures that I drew into my journal. At the end of this post is a small photo album of the trip and wedding.
