QlikView Database Connections

In QlikView, a database connection is a link to a database that allows you to retrieve data from the database and use it in your QlikView applications. QlikView supports a variety of database types, including relational databases such as Microsoft SQL Server, Oracle, and MySQL, as well as file-based databases such as Excel and text files.

The majority of well-known databases, including MySQL, SQL Server, Oracle, Postgress, etc., are accessible with QlikView. It has the ability to download data and table structures into the QlikView environment and store the outcomes in memory for later examination. Making an ODBC connection using a DSN and then utilising this DSN to collect the data are the steps required to connect to any of these databases.

Once you have established a database connection, you can use QlikView’s data modeling and visualization capabilities to analyze and present the data in various ways. For example, you can create tables, charts, and graphs to visualize trends and patterns in the data, or you can use QlikView’s data analysis and calculation functions to perform more advanced analysis.

Overall, the ability to connect to databases is a key feature of QlikView, as it allows you to access and analyze data from a wide range of sources, both within and outside your organization.

To create a database connection in QlikView, you will need to configure the connection details, including the database type, server name, database name, and any necessary authentication information. You can then use the connection to load data into QlikView using the data load editor or by using script statements in the script editor.

Connecting to the Database:

By pressing Control+E, we launch the script editor and create a new QlikView document. We find the Database area under the tab Data. Click Connect after selecting ODBC from the drop-down list. The next window appears. Select the mysqluserdns DSN, then click Test Connection. Connection Test should show as successful.
