Having is used to further filter results that have been passed through a Group By statement. Select specifies what you want returned from the query and the order of the columns. From indicates what tables will be used in the gathering of your desired data. This section includes any joins that you wish to use. The where clause allows you to filter the data that is returned against a condition you set. Order by allows you to sort the results, by column, in ascending or descending order.

Editor's Notes
- I’m Brooks Roberts and this is Michael Klocek. Just a couple of notes about myself… And Mike…
- Today we’re going to cover a lot of ground… We’re going to start off by talking about what SQL is and why you should care. Table Structure in general Basic Query structure How to connect third party applications to the database How to use the wizards to help you learn And finally, how to put all that knowledge together and build queries in what I like to call, “The Easy Way”.
- So… Why should you care at all?
- Well, let’s ask the room….
- In general, here’s a short list of important things that the appliance uses SQL for… What others can you think of? I know some of you may be asking. Don’t I have Wizards for all of that stuff?!
- Indeed you do…
- Then why would I bother to learn a new language….? Three main things drive the need/desire in my mind…
- So, for those of you who may not be familiar with SQL in the room, lets start with some basics. First off… What is SQL?
- SQL stands for Structured Query Language. This is the language that we use to interact with the database… SQL is a standard and hence, most SQL applications have interchangeable terminology and functions. At its most basic level, what makes up a database?
- Tables… So let’s talk about the structure of tables.
- As we said, tables are the building blocks of a database. Without tables, you have a pointless container with a name. Once you start adding tables to the database, that shell suddenly becomes useful as it houses data.
- As databases are made of tables, tables are made of columns and those columns are made of fields. A Table will always have a primary key… May or may not have a foreign key…
- Now.. The main point of a database, in my mind, is to house relational data. But how do we know what fields in BITS, relates to what data in BOBS? Without relational information we cannot make that assumption. This is where foreign keys come into play in most situations. One of the things you will notice with the K-Appliances are the lack of foreign keys in most of the major databases. Instead of foreign keys we use what we call Join Tables.
- Throughout the database, you will see tables that end in _JT. Within that same name are two other table names. For example here we have BITS_BOBS_JT which just in its name tells us that it is the Join Table for BITS and BOBS. BITS.ID relates to BITS_BOBS_JT.BITS_ID and BOBS.ID relates to BITS_BOBS_JT.BOBS_ID With all three tables we then know how BITS relates to BOBS.
- Now that we know how tables relate to each other within the appliance, lets look at how to build queries.
- Select Queries are built of the following items. Select From Where Group By Having Order By
- Let’s put them all in the correct written order.
- Looking at a basic query, you can see the order and that all commands are not necessarily mandatory… some can be inferred and some are only necessary in certain situations. For example, it is possible to only use Select, although its data set is highly limited without declaring FROM what it is pulling data. And, If you just want all results, Where is optional… It takes practice, but you quickly learn what all is necessary and in what circumstances.
- Arguably, the most important part of using SQL with a K-Appliance is understanding Joins. Joins make it possible to get that relational data that you are most assuredly after.
- We need to understand and utilize joins because… We use joins to group tables together into large virtual tables for the purposes of the query. There are many different kinds of joins: Inner, Outer, Cross, Self, etc… The most basic and often the most efficient are Left and Right Joins.
- When we left join a table to another table, it maintains the integrity of the data in the table to the left… For these two tables, the left join would be… And the following would be the resultant data set. As you can see, it maintained the data integrity of the table to the left…
- If I took that data set and then RIGHT joined another table to it, you will see how a right join will maintain the integrity of the data in the table to the RIGHT. As you can see… anywhere the data does not match up, the mismatched data falls away and we’re left with null values in those fields.
- Okay, we’ve learned the basics and we want to start playing with the database… We need tools!
- You can connect to the appliance with all kinds of tools. You can use Query browsers, Microsoft Access and Crystal Reports as a few examples… If you’re more comfortable using one over the other, there’s no problem. Most Query browsers now days, have native connections that allow you to connect and start querying. Microsoft applications need a special ODBC connector for MySQL. Crystal reports uses a JDBC connector. We’re going to be working with two applications that use a native connection, MySQL Workbench and Toad for MySQL.
- You can get MySQL Workbench from MySQL.COM. Scroll down and you’ll see a Downloads (GA) section on the page. From here, click MySQL Workbench
- Then select the Installer file you want.
- Toad can be found at http://www.quest.com/toad-for-mysql/ Click download the free trial, enter some personal information and….
- Acquire the freeware via the download link.
- Before we start exploring the database. Let’s setup and configure both applications. <setup, configure, explore>
