I am trying to generate a table for the Gantt chart. Table should have this format: https://developers.google.com/chart/interactive/docs/gallery/ganttchart#data-format
So,I need task name the same like taks ID, but in Query I can't use Col1 twice (I get error)
=QUERY({Tab1;Tab1};"select Col1,Col1,Col5,Col16,Col17 WHERE Col16>now() ORDER BY Col5 DESC,Col17 ";0)
The second point is that it is also not possible to merge two columns as a result, so it doesn't work:
=QUERY({Tab1;Tab1};"select Col1+Col7,Col1,Col5,Col16,Col17 WHERE Col16>now() ORDER BY Col5 DESC,Col17 ";0)
Here is my data and 2 results what I neet to get by QUERY https://docs.google.com/spreadsheets/d/1CZYgfYo6oIeONZOH6ZR5rOW615HuH4ICaoe7lj0dapw/edit#gid=0
These are such trivial things in a real SQL, is there no way to do it somehow straightforwardly in Google Query? So far I have found a combination of QUERY and ARRAYFORMULA but then there are very complicated queries - mutants. Not easier?
You don't need Query, just Arrays. You will get the first result from this code:
={ARRAYFORMULA(B3:B&" "&C3:C)\A3:A}
The second result from this code:
={A3:A\A3:A\B3:B1}
Based on your example I assume that you are not using US spreadsheet settings. If so formulas have to be change to:
First:
={ARRAYFORMULA(B3:B&" "&C3:C),A3:A}
Second:
={A3:A,A3:A,B3:B}

I see that in your real sheet you would like to compare some data with now(). You can easily do this using array I propose as a source to Query. There will you have something like this (of course now it will not work - its only an example - an array have only 2 columns, not 15):
=QUERY({ARRAYFORMULA(B3:B10&" "&C3:C10)\A3:A10};"select * where Col15>now()";0)
About Query - you can't perform arthmetic operations on column containing strings. Look at the documentation: https://developers.google.com/chart/interactive/docs/querylanguage#arithmetic-operators
