The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

I believe so. Accessing a view results in the materialization of the
result set. The complete result set must be produced before your view
could access the data.

Subject: UDF's in Views
If you include calls to UDF's within an Sql view and have an sql
statement
against that view that does not request results from the UDF's, are they
still executed anyway.
Example:
viewWithUdf
create view viewWithUdf
(fld_1, fld_2, result_1, result_2)
as
select fld_1, fld_2, udf_1(fld_1,fld_2) as result_1, udf_2(fld_2) as
result_2
from myFile
Sql statement using view
select fld_1, result_1 from viewWithUdf
In the above example, will udf_2 be called even though it is not being
requested, and will udf_1 be able to be called successfully even though
fld_2 wasn't requested.
Thank you
Joe
