It inserts data for a few product sale counts in different years. Let’s create a sample table to explore the crosstab function in SQL Server. The third column represents values assigned to each cell. The Second column identifies the category of the pivot table The first column identifies each row of the result table. The Select statement output must have three columns. The crosstab gets the select statement as a parameter, and this select should be compliant with the following conditions: The Crosstab function generates the Pivot tables in the PostgreSQL database. PostgreSQL CrossTab function Crosstab function I would recommend you be familiar with existing articles on PostgreSQL. I used the Postgres database for this article, as shown below. Ĭreate a new (sample) database for executing the queries. To use the latest PgAdmin4 tool, download it from the URL.

If you do not have Postgres installed on your system, refer to the URL for downloading software and installation guide. In this article, I am using PostgreSQL 14.5 on Ubuntu. You need the following requirements to work with this article. This article will explore the crosstab function and its different use cases. How do we create the pivot tables in PostgreSQL? Let’s find it out. SQL Server provides the PIVOT and UNPIVOT functions for working with pivot tables. You can calculate data using various functions such as count, sum, and average. Relational database tables store data in multiple rows and columns. Pivot tables are a great way to summarise data, and a handy tool for analyzing sales revenue, products sold, sales performance, etc. Pivot tables collect and organize data from different rows, columns, and tables.

PostgreSQL is an open-source,multi-operating system supported (Windows, Linux, and Unix), object-oriented relational database with reliability, performance, and feature robustness. This article will explore the use of the CROSSTAB function in PostgreSQL.
