How are they not arrays?

They have been defined as such at the top of the code:

set -A database
set -A databaseUser
set -A databasePassword
set -A packageSpecs
set -A packageBodies
set -A procedures
set -A triggers
set -A functions
set -A views
set -A sqlScripts

Its not that its writing the wrong things to the log, its that its not writing anything to the log, I expected to see the output of the sql, which is this case is a simple select statement. It seems to output to the screen as expected when I run it without the '>>'
