Madhivanan's TSQL Blog

Have you ever used getdate(something)?

Aug 8 2011 4:52AM by Madhivanan   

One of my friends asked me to ask him a very different and tricky interview question. I asked him to come up with the code that passes parameter to getdate() function ie use any code where getdate(something) is part of the code. Although it is very interesting he did not come up with an answer. Here is the answer for this trickey query.

It is not possible to pass a parameter to getdate function. The follows fails

select getdate(5)

with the following error

Msg 174, Level 15, State 1, Line 2
The getdate function requires 0 argument(s).

So the correct way is to make getdate as table name and use column alias along with it

Run this and see the output

select * from
select 1 as number
) getdate(a)

Another method is to make use of CTE

with getdate(col) as 
select 4
select col from getdate 

Have you ever thought of this getdate this way?

  • And a real world application of this would be?

  • Cris, As I said in the blog post, there is no real world case in which it is neccessary. It is only for a trickey interview question

  • Madhivanan, Sorry, I missed that.

    But in reality the code above still does not call the getdate() function and pass it a parameter. The string of characters as used in the code above is simply a text string used as a table alias.

  • Cris, that is my point. It is not about passing parameter to getdate function. In the example getdate is treated as table alias and the parameter is treated as a column alias. It is just a trick that we can use getdate that way

  • What exactly is the point of this?

    Does this relate to GETDATE in any way? As a "tricky interview" question, this is completely pointless. It serves no use in the real world and has nothing to do with the GETDATE function.

    SELECT * FROM (SELECT 1 as number) GETDATE(A) returns a single row, with a column "A" with a value of 1. SELECT * FROM (SELECT 1 as number) FOOBAR(A) returns a single row, with a column "A" with a value of 1.

    The only thing that I've learned from this is that you can add column aliases to a table alias. I'd still prefer the "traditional" way to assigning table aliases as it would be supportable.

    SELECT foobar.number AS A FROM (SELECT 1 as number) foobar

  • How about this?

    create function dbo.getdate(@id int) returns varchar(20) begin

    declare @out varchar(20)

    select @out = date from (select 1 as id, convert(char(10), getdate(), 102) as date union all select 2, convert(char(10), getdate(), 104) ) as x where id = @id

    return @out


    And then select dbo.getdate(1) returns 2011.08.17

    and select dbo.getdate(2) returns 17.08.2011

    This is it... passing parameter to getdate function, and it has to do with the getdate(). Nothing special, but maybe better answer for this question.

  • That's good example Slobodan Bogunovic. You can also use a procedure with the name getdate and pass a parameter to it

  • Slobodan, that is an excellent example.
