Sometimes one of the columns returned in the results of your report will be the result of a complex expression. For example, you might have a report with:

SELECT DPQL_PERCENT(tickets.total_to_first_reply < 3600)
 copy

It’s not very readable to show this as the column header:

You can change how the expression is displayed using AS.

After the expression, use AS 'string', where string is a readable name for the resulting column.

For example,

SELECT DPQL_PERCENT(tickets.total_to_first_reply < 3600) AS 'Percentage within 1 hour'
 copy

This results in more readable output on the table:

The readable name is also used on graphs.
