You need to convert to char first because converting to int adds those days to 1900-01-01
|
0 1 2 |
select CONVERT (datetime,convert(char(8),rnwl_efctv_dt )) |
Here are some examples
|
0 1 2 |
select CONVERT (datetime,5) |
1900-01-06 00:00:00.000
|
0 1 2 |
select CONVERT (datetime,20100101) |
does not work, because you can’t add 20100101 days to 1900-01-01 You go above the limit
Convert to char first
|
0 1 2 3 4 |
declare @i int select @i = 20100101 select CONVERT (datetime,convert(char(8),@i)) |
or
|
0 1 2 |
SELECT convert(date,CONVERT(varchar(10),columname,101)) |
