Hi,

    A query on sql - date function. I needed to convert the epoch seconds 
time to date only format[ yyyy-mm-dd]. I was trying to use the date() 
function mentioned here[1]. But this doesn't seem to be working. It returns 
date-time completely even when the date only format is specified as 
date(epochDate, 'yyyy-mm-dd') . 
Ex:  date(epochDate, 'yyyy-mm-dd') as newDate . Input: epochDate = 41943228, 
returned =  1970-01-17 10:53:48. 
Expected output was : 1970-01-17 [ yyyy-mm-dd / yyyy-dd-mm format] without 
time stamp

   If this is the bug, can you please help me with the sample example on 
how to create the user- defined sql function with parameter. I can use this 
as the solution. 
In the link [2], there are samples for creating sql user defined function 
but it is for cases without parameter.  I tried using sql syntax [ creating 
user defined function [3] with parameter] but it seems like I was not 
correct. A sample with parameter would be of great help.
