You are looking to make SQL improvements to your search queries. There are many ways you can go about doing that. In the tips that follow, you’re going to find a plan of action that will help ensure better performance optimization via SQL query tuning. Here are the suggestions that will help you make SQL improvements for the search engines.
The owner/schema name is important for each object, and it should be prefixed. If you weren’t aware of that, then you know now. The search engines are going to try and look for those schema names so they are certainly important. Have you missed the ball on this one, or is it something you already have squared away? Perhaps you have that covered, but maybe you didn’t know about this next tip.
What do you do for those nullable columns? People have different ideas about them. Maybe the phrase you use is ‘not in.’ Well, you don’t want to do that. Instead, what you want to put is ‘not exist.’ Why does the subtle difference matter so much? Well, it is just one of the changes that need to take place, but you will see why. You see, using the former causes each result to be checked by search engines, which isn’t going to help you with SQL performance.
SP stands for stored procedures, but that doesn’t mean that the initials should be included in the names. People sometimes use SP to begin the names for stored procedures. It might seem like it helps with the labelling, but you are talking about the master database being checked each time. You want to make it easier on the search engines not harder.
Now, let’s see if you use any of the following three commands. If you do, you are doing yourself a disservice. Understand that the commands are not necessary, and they can be a hindrance to your SQL performance. What are those commands? Well, one of them is ‘Group By.’
If you must absolutely use this label or term, that’s fine. There are occasions when it might be necessary, but you should avoid doing so if at all possible. What are the other two terms that you should avoid using? They are ordered by and distinct.
As you can see, you really have to watch what you dish to the search engines. You know that, but you might not have known exactly what to do and what not to do. At this point, you have been provided with some more specific information, and you can certainly learn more about what to do.
There is quite a lot more information where this came from. Are you ready to learn about a command that you actually should use? It has to do with DML operations. Have you seen the command ‘set nocount on?’ That is one command as mentioned that you will want to be sure that you use.
There are the commands to avoid and the commands that you want to use. Knowing those commands and what else is important in terms of SQL improvements is key. You want to be sure that you are doing everything correctly because you want to improve the query times not slow everything down.
You can see how the use of some commands can slow everything down. Perhaps you are using some of those commands when you shouldn’t. If that’s the case, then you are going to want to look more closely at what you are doing so that you can determine what you are missing out on. Getting everything set up correctly is instrumental in making sure your server times and SQL performance are spot on.
Which one of these tips do you need to out to the test first? Maybe you have to look over everything because it has been awhile. It happens for sure, and you want to know that you have it all taken care of so that you are able to count on improved SQL performance. Without it, you are causing yourself problems without meaning to do so. There is no need for that when specific instructions are available to help you cut down those times with the search engines.
