The Dashboard Designer provides the capability to connect to multiple types of SQL databases using the Data Source wizard. You can also use the data access API to connect to the database and select the required data in code.
This tutorial describes how to establish a connection to a PostgreSQL database and select the required data.
The appropriate data provider must be installed on the client machine. For information on data providers, refer to the Supported Data Sources article.
Creating a Data Source in the Data Source Wizard
To connect to the PostgreSQL database in the Dashboard Designer, perform the following steps.
Click the New Data Source button in the Data Source ribbon tab.
On the first page of the invoked Data Source Wizard dialog, select Database and click Next.
On the next page, select the PostgreSQL data provider and specify the required connection parameters.
Specifies the name of the PostgreSQL database server to which the connection should be established.
Specifies the port used to connect to the PostgreSQL database server.
Specifies the user name used to authenticate to the PostgreSQL database server.
Specifies the password used to authenticate to the PostgreSQL database server.
Specifies the name of the database that contains the required data.
Click Next and specify how to select data from the database.
You can choose from the following options:
Select the Query option and click Run Query Builder... to invoke the Query Builder. The Query Builder allows you to choose the required tables/columns visually and passes the resulting SQL query to the SQL String editor. Subsequently, the text of the generated query returns to the Data Source wizard.
Click Finish to create the data source.
If you apply filtering or use query parameters, click Next to specify the parameter settings.
Select the Stored Procedure option to select one of the stored procedures from the database.
Then click Next to specify the parameter settings.
