Data connections in the Data load editor let you save shortcuts to the data sources you commonly use: databases, local files, or remote files.
Data connections lists the connections you have saved in alphabetical order. You can use the search box to narrow the list down to connections with a certain name or type.
For more information, see Connecting to data sources.

- Create new connection linking to the data source (if the data connection does not already exist).
-

Referring to a data connection in the script
You can use the data connection to refer to data sources in statements and functions in the script, typically where you want to refer to a file name with a path.
The syntax for referring to a file is 'lib://(connection_name)/(file_name_including_path)'
Example: Loading a file from a DataFiles connection
This example loads the file orders.csv from the location defined in the Folder data connection. This may be, for example, a folder that your administrator creates on the Qlik Sense server.
Example: Loading a file from a sub-folder
This example loads the file Customers/cust.txt from the DataSource data connection folder. Customers is a sub-folder in the location defined in data connection.
Example: Loading from a web file
This example loads a table from the PublicData web file data connection, which contains the link to the actual URL.
Example: Loading from a database
This example loads the table Sales_data from the DataSource database connection.
Where is the data connection stored?
Connections are stored using the Qlik Sense Repository Service.You can manage data connections with the Qlik Management Console in a Qlik Sense server deployment. The Qlik Management Console allows you to delete data connections, set access rights and perform other system administration tasks.
