1. Clear the query window in Query Editor and set the display option back to showing a grid by pressing Ctrl+D. Once complete, enter the following code into the Query Editor pane. This will return the data in the ascending (the default) order of the cleared balance of our customers. SELECT LEFT(CustomerFirstName + ' ' + CustomerLastName,50) AS 'Name', ClearedBalance Balance FROM CustomerDetails.Customers ORDER BY Balance 2. Execute the code; this will produce the results shown in Figure 8-30.

Figure 8-30. Altering the order by balance 3. We can also complete the same query, but have the cleared balance in descending order rather than ascending order. This is simply done by placing DESC after the column name. Change your code as detailed here: SELECT LEFT(CustomerFirstName + ' ' + CustomerLastName,50) AS 'Name', ClearedBalance Balance FROM CustomerDetails.Customers ORDER BY Balance DESC 4. Execute the code; this will produce the results shown in Figure 8-31.

It is possible to use more advanced techniques for finding records where a mathematical operation doesn t quite fit; for example, say someone is trying to track down a customer, but doesn t know the customer s full name or does know the first part of his or her surname but doesn t know how to spell the full name. Suppose you know that the surname ends in Glynn as in the first customer we added, but you don t know if it starts with Mc, Mac, or even M. So how would this be put into a query There is a keyword that you can use as part of the WHERE statement, called LIKE. This will use pattern matching to find the relevant rows within a SQL Server table using the information provided. The LIKE operator can come with one of four operators, which are used alongside string values that you want to find. Each of the four operators is detailed in the following list. They can be used together, and using one does not exclude using any others.
Note
LIKE is NOT case sensitive unless you have the SQL Server instance set to a collation that is case sensitive.
%: This would be placed at the end and/or the beginning of a string. The best way to describe this is through an example; if you were searching the customers who had the letter a within their surname, you would search for %a% , which would look for the letter a, ignoring any letters before and after the letter a , and just checking for that letter within the first name column. _: This looks at a string, but only for a single character before or after the position of the underscore. Therefore, looking in the first name column for _a would return any customer who has two letters in his or her first name where the second letter is an a. In our example, no records would be returned. However, if you combined this with the % sign and searched for _a%, then you would get back Jason Atkins, Ian McMahon, and Ian Prentice. You would not get back Vic McGlynn, because a is not the second letter. []: This lets you specify a number of values or a range of values to look for. For example, if you were looking in the player s first name for the letters c-f, you would use LIKE "%[c-f]%". [^...]: Similar to the preceding option, this one lists those items that do not have values within the range specified. The best way to learn how to use LIKE is to see an example.
