Question

Converting integer dates into string values in TSQL

   Declare @Year INT = 2020
   Declare @Quarter TINYINT = 1

How to convert into string to show as 2020 Q1

Answer 1

我会使用CONCAT因为它会为您处理数据类型转换。

SELECT CONCAT(@Year, ' Q', @Quarter) as QtrString

Answer 2

Eric Brandt has a great option.

Adding Another option, if you want to do the data transformations yourself, use:

Declare @Year INT = 2020
Declare @Quarter TINYINT = 1

Select CONVERT(varchar(4), @Year) + ' Q' + CONVERT(varchar(4),@Quarter);

Answer 3

use datefromparts

declare @Year int=2020
declare @Quarter int=1;

select datefromparts(@Year, case when @Quarter=1 then 1 when @Quarter=2 then 4 when @Quarter=3 then 7 when @Quarter=4 then 10 end, 1)

output

2020-01-01
