How to Build a .NET RDL Report Using PostgreSQL

PostgreSQL is one of the most used open-source data sources. It has an interface that makes it easier to use than MySQL.

Recently one of our customers asked how to bind ActiveReports to a PostgreSQL database, so I decided to write this blog article to help other customers who work with PostgreSQL.

Create a Table in PostgreSQL

First, we create a table named simple_table in the PostgreSQL pgAdmin panel.

Set Up a Data Source for the Report

I want to create an RDL report and bind it to the simple_table in MyTestDataBase using PostgreSQL.

I'm using the ODBC driver (PostgreSQL Unicode 32/64 bit) provided by PostgreSQL Global Development Group to connect my RDL report to PostgreSQL. If you haven't installed the PostgreSQL driver, you can follow the steps in the first part of this article.

ODBC PostgreSQL Unicode Driver

Now we can link the data source to our RDL report using a connection string like this:

Driver={PostgreSQL UNICODE};Server=localhost; Port=5432;

Database=MyTestDataBase; Uid=postgres; Pwd=123456;


RDL Report Data Source

Now we add a data set to the data source using a SQL query like this:

SELECT * FROM simple_table

Design the Report

Now we are all set to design the report with the data set. Let's drop a Table onto the report and bind it to the dataset fields.

Binding Table Cells to PostgreSQL Dataset Fields

So we have created an RDL report bound to a PostgreSQL database without writing a single line of code. Amazing, right?

Let's preview the report and see how it looks.

Pretty cool stuff!
