Viewing function definitions in Vertica

Wed, 05 Jun 2013 09:28:00 +0100

I don’t know if you have tried this. But I did try to read function definition from the system tables in Vertica.

I used the table called USER_FUNCTIONS which is a table in the V_CATALOG system schema. More details can be found here: https://my.vertica.com/docs/6.1.x/HTML/index.htm#15021.htm

But unfortunately when I try and do something like this:

vertdeva01:20130604-113434 > select function\_definition from v\_catalog.user\_functions where schema\_name='calc' and function\_name='getCYForDate';  
\----------------------------------------------------------------------------------------------------------------------------------  
RETURN to\_date(concat(((((date\_part('year', (processDate)::timestamp))::int - CASE WHEN ((date\_part('month', (processDate)::time  
(1 row)

If you notice the function definition is only partly visible. The rest of it gets truncated. I don’t know how to set it right. If you know how, feel free to comment on this post.

VSQL extract data into file

Hey there! So you use Vertica and vsql to interact with your tables. Ever had those times when you wanted to take stuff from your table and paste it into Microsoft Excel for sending it off to someone not so technically acquainted with Vertica?
You could write a script to do that for you. But if you just had to do it within a vsql session you also have options to do it.
