How to single sort multiple queries by the same condition in sheets?

I am trying to pull multiple sheets into one using the query function like so

={QUERY(Sheet2!A2:B, "SELECT A, B WHERE A <> ''");
  QUERY(Sheet3!A2:B, "SELECT A, B WHERE A <> ''")},...

doing this is fine but I would like the queries to be mixed in as to show a compiled list by the date in an ascending order any ideas on how to do this?

Also, I have tried to include sort by statements but it does not mix all the queries into one.

Solution

all you need to do is to wrap it into another QUERY:

=QUERY(
 {QUERY(Sheet2!A2:B, "SELECT A, B WHERE A <> ''");
  QUERY(Sheet3!A2:B, "SELECT A, B WHERE A <> ''")},
 "order by Col1")
