如何在 SQL 服务器中将 varchar 转换为日期

Question

I would like to have a datetime variable composed of the current date and a time that I would have defined.

I tried this:

DECLARE @limit datetime2;
SET @limit = CONVERT (date, GETDATE()) + ' 05:00:00'

But this way doesn't work well because I can't add a varchar to a date .

Answer 1

You can try:

DECLARE @limit datetime2;
SET @limit = DATEADD(day, DATEDIFF(day, 0, GETDATE()), '05:00:00')
select  @limit

Answer 2

You can also achieve by using CONCAT in SQL

DECLARE @limit datetime2;
SET @limit = CONCAT(CONVERT (date, GETDATE()) , ' 05:00:00')
SELECT @limit
