Tiered Storage

Storage costs are constantly rising, especially for databases as we gather more and more data. However not all of our data is necessarily the same priority or requires the same hardware. Steve Jones talks about the benefits you might get if you can tier your storage.

Find SQL Server databases where log file is too large

I support thousands of databases and I'm running across situations where I have a database that has a data file of a couple hundred megabytes and the associated log file is gigabytes in size! I understand this is because I may not have my transaction log backups scheduled properly. What I'm interested in is an easy way to identify these situations where the SQL log file is too large, so I can go in and further analyze these problem databases without needing to look at each database.

How to remove parent as a child from a SSAS parent child dimension

In a parent child dimension, when an attribute's usage type is set as Parent and browsed from a client tool, many designers as well as users may get confused based on the displayed results. For example, when you browse a parent attribute in a parent child dimension like Employee and say the parent attribute is Employees, you can browse data members from the parent node until the deepest available level of the child node. By default you will find each parent member having a child member with the same name even though this member might not exist in the data. From a user experience point of view this is not a desirable way of browsing a parent child hierarchy because it may get confusing. In this tip we will look at an example of this issue and how to solve this problem.

The Titanic Cloud

The outage at Amazon's Web Services recently affected a lot of different companies. However not everyone was affected. The reach of the cloud and the competition for attention means that while we have to learn to expect failures, they are not necessarily evenly distributed.

Question of the Day

Getting the Average

I have this data in the dbo.Commission table in a SQL Server 2022 database. 

salesperson commission
Brian       12
Brian       16
Andy        7
Andy        14
Andy        21
Steve       20
Steve       NULL
All the data is a varchar, and I decide to run this query to get the totals for each salesperson. 
SELECT SalesPerson
     , AVG(TRY_PARSE(Commission AS int)) AS TotalCommission
 FROM commission
 GROUP BY SalesPerson
GO
What average commission is calculated for Steve?
