Thank you very much, Sayan and Dominic!
'' indicates that a pair of single quotation and they represents that the
starting and ending of the text literal here my double quote is
coincidenctally the text literal.
I can also consider using q'[......]' to do the assignment for the entire
variable of VARCHAR2 v_sql.
Sayan's suggestion about gist.github.com is very great, I'll try it as well
next time.

You say you know that the column alias should be in double quotes, e.g.as “10:30” but none of your examples provides code which actually produces

e.g.
create view v1 as
select 1 as 10:30 from dual; --wrong
vs
create view v1 as
select 1 as '10:30 ' from dual; --wrong
vs
create view v1 as
select 1 as "10:30" from dual; --right

|| '"'||v_samp_time.sample_time|| '" '
(single quote then double quote then single quote)
