Ok, thank you for that hint. But it is still very unconvenient. How can I
define a view based on your suggestion? I want to have something like
CREATE VIEW foo AS SELECT {if has stddev then stddev(...) else null} FROM ...

You can check if what you need is available on a connection and either load it
if needed or just abort:
sqlite> select * from pragma_function_list order by 1, 2;
name builtin
- --
aavg 0
abs1
acos
select name from pragma_function_list where name == 'M_Pi' collate nocase;
returns the name of the function if it exists. See pragma function_list

+1 for that as had already been in consideration for version 4

I agree in that not every math function can be included by default. My problem,
however, is that I cannot know whether a user uses my self-compiled version
with built-in extension-functions.c, or a downloaded version from sqlite.org.
It would be very, very helpful (especially regarding views!) t
Before starting to support SQL2016 features, I would suggest support for
missing features of older SQL standard versions first ;)

If realloc() fails (see // Here.), the memory occupied by zLine will not be
de-allocated.
(http://www.c-faq.com/malloc/realloc.html)
static char *local_getline(char *zPrompt, FILE *in){
char *zLine;
int nLine;
int n;
nLine = 100;
zLine = malloc( nLine );
if( zLine==0 ) return 0;

Hi Richard,
I just realized I didn't include the mailing list in my previous response
to you, so I'm doing that now with the contents of the SQL file I sent you
previously. I've also included a copy of my original email in plaintext as
the HTML formatted SQL queries got mangled when it was process
Since there are people posting who appear know about these things …
Suppose I want SQlite to handle my own type. Or to do its best to simulate
that. IP address, x/y location, something like that. What should I be doing ?
Do I store BLOBs and define my own COLLATEs ? Or didn't I read somewhe

User-defined types are quite important if you’re doing fancy stuff in
user-defined functions, where data that’s stored in tables as blobs has an

geometries I use with Postgis & Spatialite - I don't have a database without
them.
Can anyone come up with a data domain for which location has no relevance?
I used to think I had some (like taxonomies & dictionaries), but I've been
corrected in each case :-)
also IP addresses

That's an interesting aside. It would make an interesting OT thread,

Thanks for the test case. This problem should now be fixed on trunk.
Please try it out and let us know if you encounter any additional

Traditionally "math library" functions provided by the various language

Yes, I expected some pushback. However, my post was to save the next person
having to search for answers. I did not expect to requote the top line of
the page I listed?

How we can anyone document functions that do not exist?, they are
infinite and many of them (most) are not currently known to humanity.
Also, if somewhere it said "SQLite cannot do sqr() it would lie - sure
vanilla sqlite might not, but there are many ways in which it does.

I'm not addressing the documentation question, but extended math functions
have been available since 2010.

Which ones should the documentation mention ? Can you find us a specification
of SQL which includes that these functions
I'm often scrambling to decide whether to do complicated queries in SQL or
my own code?
...Getting oh so close to a working query, only to fail at function not
defined?!!
