The PIVOT operator in SQL is so called because it acts as a PIVOT (i.e. INSERT INTO TestPivot VALUES(2016, 'December', 6655.00) PIVOT literally means the central point around which something revolves. INSERT INTO TestPivot VALUES(2016, 'November', 6128.00) And PIVOT runs aggregations where they're required on any remaining column values that are wanted in the final output. INSERT INTO TestPivot VALUES(2016, 'October', 5548.00) PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output. INSERT INTO TestPivot VALUES(2016, 'September', 5916.00) Using PIVOT operator, we can perform aggregate operation where we need them. PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output. INSERT INTO TestPivot VALUES(2016, 'March', 3217.00) PIVOT relational operator converts data from row level to column level. INSERT INTO TestPivot VALUES(2016, 'February', 2280.00) INSERT INTO TestPivot VALUES(2016, 'January', 4190.00)

INSERT INTO TestPivot VALUES(2015, 'December', 6655.00) INSERT INTO TestPivot VALUES(2015, 'November', 6128.00) INSERT INTO TestPivot VALUES(2015, 'October', 5775.00) INSERT INTO TestPivot VALUES(2015, 'September', 5838.00) INSERT INTO TestPivot VALUES(2015, 'February', 2158.00) Most questions were about the column list in the PIVOT statement. However, I’ve seen quite a few questions about this operator. PIVOTs are frequently used in reports, and they are reasonably simple to work with. INSERT INTO TestPivot VALUES(2015, 'January', 4343.00) Pivots in SQL Server 2005 can rotate a table, i.e.

Ideally you would not want to use reserved keywords as column names but since this post is geared towards someone who is new to using PIVOT I wanted to make the translation as simple as possible. For the purposes of this example I have oversimplified this table. The script below will handle this by creating a table named TestPivot on the TSQL2012 database. Pivot tables are easily created by office users using Microsoft Excel or MS Access. The first step will be to create the table I will be using to store the data. T-SQL Pivot Tables in SQL Server - Pivot Table Tutorial with Examples What is a Pivot Table A pivot table is a frequently used method of summarizing and displaying especially report data by means of grouping and aggregating values. To better illustrate this I have outlined all the necessary steps from creating the table, populating it with data, and then querying it using two different pivot queries to demonstrate various techniques that can be implemented to summarize the data.įor the purposes of this example I will be using the TSQL2012 database. Though this concept can be a bit daunting for beginners, it’s actually pretty easy to implement assuming you understand the data you are working with. The PIVOT operator, simply put, allows you to transform data from rows to columns as well as perform aggregations as the data is being transformed. SQL Server also offers a more powerful feature for pivoting data. Let’s apply these steps in the following example.įirst, select category name and product id from the production.products and production.As anyone who has ever worked with financial data within Excel knows, the ability to pivot data is an essential tool for gaining a deeper understanding of the data you are reviewing.
