Script to calculate the Median value for SQL Server data

  • Article

The standard SQL language has a number of aggregate functions like: SUM, MIN, MAX, AVG, but a common statistics function that SQL Server does not have is a built-in aggregate function for median. The median is the value that falls in the middle of a sorted resultset with equal parts that are smaller and equal parts that are greater. Since there is no built-in implementation for the median, the following is a simple solution I put together to find the median.

Pivoting, Unpivoting and Aggregating

  • Article

We asked Phil Factor to write a nice simple quick-start guide about aggregation, pivoting and un-pivoting techniques. To do so, he takes us all the way from getting the data from a published source, transferring it to SQL Server, un-pivoting it, storing it in a relational table, aggregating it and finally pivoting the data in a variety of ways.

Question of the Day

Specifying the Collation

I am dealing with issues on my SQL Server 2022 instance related to collation. I have an instance collation of Latin1_General_CS_AS_KS_WS, but a database collation of Latin1_General_CI_AS. I want to force a few queries to run with a specified collation by using code like this:

DECLARE @c VARCHAR(20) = 'Latin1_General_CI_AS'

SELECT  p.PersonType,
        p.Title,
        p.LastName,
        c.CustomerID,
        c.AccountNumber
 FROM Person.Person AS p
 INNER JOIN Sales.Customer AS c
 ON c.PersonID = p.BusinessEntityID
 COLLATE @c
Will this solve my problem?
