2.9. SQL Connections

One of the key functionalities of OnTask is to be able to merge data from multiple sources. Section Data describes the functionality available to perform these operations. Some of them, however, require special configuration from the tool administrator. This is the case when uploading and merging data from a remote database that allows SQL connections. These connections must be first defined by the administrator and are then are available to the instructors.

The screen to manage these connections is accessed clicking in the item SQL Connections at the top menu bar. This link is only available for those users with the administration role.


Each connection can be defined with the following parameters:

Name (required)

Name of the connection for reference purposes within the platform. This name must be unique across the entire platform.


A paragraph or two explaining more detail about this connection.

Type (required)

Type of database connection to be used. Typical types include postgres , mysql , etc.


Driver to be used for the connection. OnTask assumes that these drivers are properly installed and available to the underlying Python interpreter running Django.


User name to connect to the remote database.


Password for the database. If not give, it will be required at execution time.


Host name or IP storing the remote database


Port to use to connect to the remote host

DB Name (required)

Name of the remote database


Name of the table in the remote database containing the data to upload/merge. If not give, it will be requested at execution time.

Once a connection is defined, as described in SQL connection , all the data in the table will be accessed and loaded/merged into the current workflow.

The operations allowed for each connection are:


Change any of the parameters of the connection


View the values of the connection


Create a duplicate of the connection (useful to reuse configuration parameters)


Remove the connection from the platform.
