  • 1.  Displaying Date-Time Field.

    Posted Thu May 26, 2022 03:07 PM
    All three of these SELECT's return the same value - 1/1/2010 12:00:00 AM.  


    SELECT DATETIME('2010-01-01') as start_date;
    SELECT (DATETIME '2010-01-01') as start_date;
    SELECT CAST('2010-01-01' AS TIMESTAMP) as start_date;

    Is there any preference for one over the other two?

    Hello David,

    Internally above query are using timestamp function. For end user it does not matter what way one uses / calls the function, but using CAST('2010-01-01' AS TIMESTAMP) makes obvious sense.

    Thank you for your thoughts Sachin. 

    Yep, I'll go ahead and use the CAST in my code.
