A Look at Case Sensitivity

Unlike some of the other coding languages that are out there and that you may be tempted to use on your database searches, you may find that the case sensitivity in SQL is not going to be as important as it is in some of those other ones. You are able to use uppercase or lowercase words as you would like, and you can use either typing of the word and still get the part that you need out of the database. It is even possible for us to go through and enter in some clauses and statements in uppercase or lowercase, without having to worry too much about how these commands are going to work for our needs.

However, there are a few exceptions to this, which means there are going to be times when we need to worry about the case sensitivity that is going to show up in this language a bit more than we may want to. One of the main times for this is when we are looking at the data objects. For the most part, the data that you are storing should be done with uppercase letters. This is going to be helpful because it ensures that there is some consistency in the work that you are doing and can make it easier for us to get the results that we want.

For example, you could run into some issues down the road if one of the users is going through the database and typing in JOHN, but then the next person is typing in John, and then the third person is going through and typing in john to get the results. If you make sure that there is some consistency present, you will find that it is easier for all of the users to get the information that they want, and then you can make sure that you are able to provide the relevant information back when it is all done.

In this case, working with letters in uppercase is often one of the easiest ways to work with this because it is going to make it easier and the user is going to see that this is the norm in order options as well. If you choose to not go with uppercase in this, then you should try to find some other method that is going to keep the consistency that you are looking for during the whole thing. This allows the user a chance to figure out what you are doing, and will help them to find what they need with what is inside of their queries.

As you go through this, you may notice that these queries and transactions that you are able to create for the database that you are working on are going to be important to the whole system and ensuring that it is actually going to work in the manner that you would like. In the beginning, this may feel like a lot of busywork to
