The Ten Commandments of SQL Server Monitoring

It is easy to get database monitoring wrong. There are several common-sense rules that can make all the difference between a monitoring system that works for you and helps to avoid database problems, and one that just creates a distraction. Adam Machanic spells out the rules, based on his considerable experience with database monitoring. More »

Editorial - Better Coding, More Savings

I'm sure most of us would like to think that we write fairly efficient code. However the reality for many of us might be that we don't actually know. Many of us use the same patterns and practices that we've been using for a long time, rarely changing. When we learn a new technique or find a different way of coding that works better, we tend to then use that method over, and over, and over, and over again.

I would guess that if many of us profiled our code, and examined the CPU and network bandwidth we consume, we might be surprised at what we find. CPU and network usage isn't something we are often concerned about. We assume that we've bought a machine and we should be able to use as much of it as we can at any point in time. That's not the best approach, but since we often have more hardware than we need for many processes, it works. It also explains why so many applications struggle as the load increases. They're not coded efficiently.

If you're going to work in the cloud, you better learn to code more efficiently, mostly because it costs money. If you think about your design, you can reduce the amount of resources you use. In the cloud this translates to less cost. In the on-premises world, this means better performance and higher scale. It also means less complaints and phone calls.

Scaling up an application can be hard, but much of the struggle comes from poorly coding your application in the beginning. Most of us have heard the saying that it takes less time to do it right the first time. That's true in many situations, and it's true for your application development. Learn to write more efficient code and use patterns that conserve resources. You'll find your applications will run better, no matter what type of environment hosts them. If you're not sure what patterns and practices work well, read an article or ask a question and find out what efficient techniques others use.

Yesterday's Question of the Day

What will be the data type assigned for the columns in the temp table when to run this below query? Please select answer.

select * into #temp from 
(
 select NULL col1, NULL col2 
 union all 
 select null, 'Que'
) A

Answer: Int, Varchar(3)

Explanation: This query will create the int data type in Col1 as the default in the implicit conversion if all the values are specified as NULL in a particular column. Otherwise it will create the data type of the values in the column. In this case Varchar(3) as the result of implicit conversion.

Ref: None found. One appreciated.
