Edit the data load script

You write the script in the text editor of the Data load editor. Here you can make manual changes to the LOAD or SELECT statements you have generated when selecting data, and type new script.

The script, which must be written using the Qlik Sense script syntax, is color coded to make it easy to distinguish the different elements. Comments are highlighted in green, whereas Qlik Sense syntax keywords are highlighted in blue. Each script line is numbered.

There are a number of functions available in the editor to assist you in developing the load script, and they are described in this section.

Accessing syntax help for commands and functions

There are several ways to access syntax help for a Qlik Sense syntax keyword.

Accessing the help portal

You can access detailed help in the help portal in two different ways.

• Click in the toolbar to enter syntax help mode. In syntax help mode you can click on a syntax keyword (marked in blue and underlined) to access syntax help.

• Place the cursor inside or at the end of the keyword and press Ctrl+H.

Information noteYou cannot edit the script in syntax help mode.

Using the auto-complete function

If you start to type a Qlik Sense script keyword, you get an auto-complete list of matching keywords to select from. The list is narrowed down as you continue to type, and you can select from templates with suggested syntax and parameters. A tooltip displays the syntax of the function, including parameters and additional statements, as well as a link to the help portal description of the statement or function.
