Yes you do have the column, but your first part doesn't tell the query
which table to use.
UNION is used to join the result of queries together. Each of those
queries must be correctly formed. The first part of your SQL (before
the first UNION) does not contain a FROM clause, so MySQL tells you
there is no column called 'solarLandingDateTime' because you have no
table. This same problem applies to each part of your unions.
