I could easily go create that index, rerun the query, see if I see some improvement. Immediately, it tells me I’m missing an index, that’s probably why I had that over a 191,000 reads that was reporting. Of course, you have execution plans available to you, you can enable the execution plan and then run your query. So you have to think if your query returns a lot of data, it’s going to have a bigger impact to your user than just the time name that the CPU spent, always keep that in mind. So here you can see it shows elapsed time as well and then I can see that four seconds from SQL management studio.Ī lot of times when you’re looking at reporting of slow queries from SQL server, it’s based on CPU time, not the total time. I can get an idea of how much actual CPU time was spent on the database, not the total elapsed time.

I can come in here and I can see CPU time. When I enable the SET STATISTICS ON of the time. It’s important to understand that that’s not necessarily how much CPU was used. Notice on the bottom right of the screen here says my query took four seconds to execute. The SET STATISTICS TIME ON is also a really good one. Now even if you’re not a DBA, this might be enough information for you to go and see, do I need a better index? Am I not quitting the index right way? Do I need to maybe go to my DBA and have them help me? This just gives you some basic information, is your query good or bad, at least a high level. I probably need to do some kind of database tuning. So in this example, I can see my store procedure is doing 191,000 logical reads, that’s a lot of logical reads. It’ll show you all the tables that your query hit and give you some idea of how many reads it did. All you have to do is run this command and then rerun your stored procedure, or any kind of database query for that matter, then you can jump over to the messages tab here. These are definitely things that you should know about. What I want to show you first is this SET STATISTICS IO ON and SET STATISTICS TIME ON. So right off the bat here, I’m looking at a basic stored procedure.

Today I’m going to tell you some of my favorite tips and tricks about how to write better database queries, just using some simple tools that you already have access to or free tools that you should know about. Now I’m not a DBA but I’ve been a developer for a long time and I’ve pretended to be a DBA many times. Hello everybody this is Matt with Stackify.

If you have this problem, deleting the report entirely and reentering your code with a different report name will usually fix the issue.In the first episode of DevCheats, CEO and Founder of Stackify, Matt Watson, demonstrates some tips, tricks and free tools to help write better SQL queries. Cyrious appears to store these reports in such a way that changes in the code are not updated in the stored code. Note: If you are using Cyrious Sequel reports capability for reports or report testing, you will often find that sequel reports with errors do not respond to your corrections. Then add Select statements, Joins, or Where conditions until you have identified the errant code. Sequel reports usually complete in blink time so if you are not getting the result you expect very quickly, don't hesitate to Force Quit and simplify your code to where you are sure it is error free. Test all Sequel code carefully as bad code can hang or degrade your system performance. However, we have found that even in these cases this method provides a quick bases and good head start for even a complex query, There are occasionally other fields which the user will have to add manually to the Where statement. However, date algorithms must be manually added with the Cast(“Date” as DATE) function of Sequel. This method works to construct the base for almost all Sequel reports or macros one would need.
