Did you mean "concatenate" and not "merge"? if you wanted these dates
why aren't they parameters to a procedure?

Since headers are a display concept, they have no place in a database
at all! Why not keep throw in the paper size colors to used for the
reports along with the headers??

And the final error is violating ISO-8601 date formats.

That certainly is your problem. You have screwed up your design and
your whole approach to RDBMS. Get help from someone who has some idea
of what they are doing.
