Hi , Excellent demonstration of UDFs. Just wondering if you can tell us few use cases of JAVA UDF which can't be done via VBScript or SQL UDFs. Basically i am looking for bit more information on the usage and use cases (real life practical examples) of each of the UDF types. I would appreciate if you can throw some examples please?
Hi team, i seen one bug while writeing UDF using sql code when i put an extra closed bracket ")" then only code compileing, otherwise showing compilation error. any idea about this create or replace function cal_profit(rq number,pp number,sq number) returns number as $$ select ((rq-pp)*sq)); $$; create or replace function cal_profit(rq number,pp number,sq number) returns number as $$ null); $$;
Waiting was over Again same mind blowing explanation… Love it. Kindly share the videos early so that we can practice well…When can I accept this course would complete….? Still how many days & courses.
Where can we find the diagram with all snowflake topics that you show at starting of each video? It would be handy to have a quick overview of all topics.
Can you show an example where a UDF consists of multiple SQL (not Javascript) statements? For example: DEFINE... UDF(int x); int y = x^2; int z = x+y; ... (other statements) ... return z The logic is fairly complex to be incorporated into a single statement. Thank you.
Updated code without compilation error: create or replace function calculate_profit(retail_price number, purchase_price number, sold_quantity number) returns number(10,2) comment = 'this is simple profit calculator' as $$ select (((retail_price - purchase_price) * sold_quantity)) $$; -- Just added an extra open bracket in the select statement
I had never thought there will be so many concepts in UDF. Great explanation !!!
good to know that this tutorial helped you.
thanks for your video. How do you update or replace a function?

Very cool videos!!! Thanks a lot for your work!!!

Hi team,
i seen one bug while writeing UDF using sql code when i put an extra closed bracket ")" then only code compileing, otherwise showing compilation error.
any idea about this
create or replace function cal_profit(rq number,pp number,sq number)
returns number
as
$$
select ((rq-pp)*sq));
$$;
create or replace function cal_profit(rq number,pp number,sq number)
returns number
as
$$
null);
$$;
thanks for sharing this issue...
Waiting was over
Again same mind blowing explanation…
Love it.
Kindly share the videos early so that we can practice well…When can I accept this course would complete….? Still how many days & courses.
thanks a lot Sangapu..
those who are getting the select compilation error, just remove ; after the select statement and write parentheses in correct way it will work 100%.
Hi, how can we get the scripts you were running for practising
here you go toppertips.com/user-defined-functions-in-snowflake
can we use STRICT instead of RETURNS NULL ON NULL INPUT
Would suggest to try it yourself and observer the behavior and do let us know..
bhai ek baat batana jar file stage se agar purge ho jaaye toh phir JAVA UDF kaam nai karega , is there any work around for this?
Never tried that..but will check.
@@DataEngineering ok your good name
Where can we find the diagram with all snowflake topics that you show at starting of each video? It would be handy to have a quick overview of all topics.
Will see how can I make them available via my website.
Can we do the same using Python? Can you please make a video on this, thanks.
Yes, you can do it. Will do a video soon.
@@DataEngineering That's amazing, looking forward to that video!
Can you show an example where a UDF consists of multiple SQL (not Javascript) statements? For example:
DEFINE... UDF(int x);
int y = x^2;
int z = x+y;
... (other statements) ...
return z
The logic is fairly complex to be incorporated into a single statement. Thank you.
create function ddl must have one single SQL statement.. need to check once again but multiple statement is not supported.
@@DataEngineering Thank you so much for your reply. I thought so. I will write the UDF in Javascript that supports multiple statements.
Bro is this content is enough to get a job?.
Snowflake is a tool and if you know the Data Warehouse + Snowflake.. this course will help you
Please dont skip the steps its very disgusting when ur doing explanation videos
Thanks for you note, but did not understand your concern. Could you be more specific and time stamp in the video where it had happened.
You're ungrateful
13:58 there is some glitch..

Updated code without compilation error:
create or replace function
calculate_profit(retail_price number, purchase_price number, sold_quantity number)
returns number(10,2)
comment = 'this is simple profit calculator'
as
$$
select (((retail_price - purchase_price) * sold_quantity))
$$;
-- Just added an extra open bracket in the select statement
Thanks, will correct it in my blog page.
unable to send you message on instagram
It should not be the case.. I get lot of messages... and nobody has ever raised this issue..
