Let us take a closer look at how to create a crosstab query in an SQL server. AtBobcares our MSSQL support services can give you a detailed overview of the whole process.

Introduction to SQL Server Crosstab Query

Crosstab is a circumstance in which we demand that the results of the table or query be rotated. It is done in such a way that the data in the columns to display horizontally and the data in the rows of the table is displayed vertically. A pivot table or a crosstab is a data representation that rotates.

There are several methods for creating a crosstab query in an SQL server.

Crosstab Format in SQL Server

To demonstrate the format, take the following scenario: we have existing tables named sales details in the database named abcd. It contains the monthly sale amount of each month beginning in 2010 and has columns preserved in the table that include the year, month, and sale of that month.

The table contents are present in the output of the query statement below.

SELECT * FROM sales_details;

The execution of the above query expression results in an output, where we have data up to the seventh month of 2012, and the table has a total of 31 entries. To continue with the create crosstab query in we must calculate the total sale amount for every year.

Now, calculate the total sale amount for each year and display the monthly values and sale amount values horizontally.

This will allow the year and their respective month details to show further after the year column. And the final column should include the total column, which will show the yearly total sales, as shown in the below format.

Now we’ll look at how we may display the data in the crosstab manner seen above using both the case statement and the pivot statement.

Let us first compute each year’s total and display all of the year’s data in the tables to create Crosstab Query in SQL server.

We will use a simple query to group the results depending on the year. Arrange the results on a year-column value basis. After that use the sum aggregate function to get the total sale for each year.

SELECT YEAR,
SUM(saleAmount) AS Total
FROM sales_details
GROUP BY YEAR
ORDER BY YEAR;

This command line will generate the Output successfully completing the process.
