Emil Ibrishimov commented on HIVE-691:
--------------------------------------
So far, I added "DESCRIBE FUNCTION" and "DESCRIBE FUNCTION EXTENDED":
query: DESCRIBE FUNCTION conv
conv - Convert numbers between different bases
query: DESCRIBE FUNCTION EXTENDED conv
conv - Convert numbers between different bases
conv(num, from_base, to_base) - convert num from from_base to to_base; if
to_base is negative, treat num as a signed integer,otherwise, treat it as an
unsigned integer.
There are two types of description - short and extended - for each udf. They
are added as annotations. Is that what we are looking for? I can also add
"DESCRIBE FUNCTIONS <regexp>" that show the short descriptions of all functions
that match <regexp> if you think it is a good idea?
> show documentation for user defined functions

> There are lot of functions and more of them will be added. I think it is
> cumbersome to update wiki or ask users to go to wiki to find out
> documentation. instead each user defined function can have an annotation
> containing documentation and 'show functions' command or similar can show the
> documentation to users on command line. it will also be easier to update the
> documentation along with code.
