在SQL Server 2008和2012中并置

Question

I have this concatenating function that works fine in SQL Server 2012:

declare @reportN nvarchar(255)
set @reportName = concat(year(getdate()), '-',33);

select @reportN

Which gives result 2013-33

I also have SQL Server 2008 which doesn't support concat function so when I try to do it following way.

declare @r nvarchar(255)
set @r = (year(getdate()) + '-' + 33);
select @r

I get result of 2046 basically it adds it. Can you let me know how to fix it so I get it result of 2013-33. Thanks

Answer 1

You can just cast the year as a string:

  declare @r nvarchar(255)
  set @r= CAST(YEAR(GETDATE()) AS CHAR(4)) +'-33';
  select @r

The CONCAT() function in 2012 converts all inputs to strings, you need to explicitly do this prior to 2012 if you want to concatenate strings.

Answer 2

You need to make your year(getDate()) a CHAR (or some other text). You are concatenating it to an integer 33. Since year() returns an INT and you are concatenating to an INT (33) it returns and INT.

declare @r nvarchar(255)
set @r=(CONVERT(CHAR(4), year(getdate()))+'-'+'33');
select @r

Answer 3

Convert 33 to varchar:

declare @r nvarchar(255)
      set @r=(convert(varchar(4),year(getdate()))+'-'+'33');
      select @r
