Hi there,
I am trying to combine 2 text variable togther to form the name of a
VIEW. example

SELECT * FROM ( 'april'||'may') ;

The table (or view) part is not a character string but an identifier.

I think you want to use EXECUTE from within a pl/pgsql function to
construct and execute a query dynamically - have a look at this:

HTH,

That's the only way to do it (modulo that you can do this in any of the
PLs not only plpgsql) ... but a more general point is that the OP is
trying to swim against the tide. Almost certainly, rethinking the
design of those views is called for: try to merge them into one view.
