google sheets – How to combine two QUERY results in a column

I have a following query

= query (XX! A2: A; "select A where A> 50")

and

= query (YY! A2: A; "select A where A> 50")

How can I combine these two data sources so that I do not have two separate columns for data processing?

  • the best would be if 1st row of XX is followed by the 1st row of AA, 2nd row followed by 2nd row … and so on
  • If the above option is not easily possible, it is possible that a query is followed by one second (if I wait correctly until the beginning of the second is moved with new data added in the first)

Thank you for any help
