Error when using MySql functions to calculate columns in DBQuery

I can't use a sentence using MySQL functions to calculate some column in a DBQuery.

Environment:
PHsPeed V1.3.0 B7 - x64, PHP 7.4.5

Steps to reproduce:
Just add a DBQuery and set the SQL property to

select concat('This is','a sample') as mycolumn

Then generate code and try to run the form.  The field name ignores the alias, and is set to "concat('This is".  I tried a variety of functions, like "if" or "curdate", with same results.

Workaround:
Of course I could create a VIEW with the aliased column, but is not always feasible
