What is the data of "yourcolumn" (the original column)?

If it's already datetime, and you just want to strip the time off, then do this instead:

DATEADD(DAY, DATEDIFF(DAY, 0, yourcolumn), 0)

I was trying something like this below..

select Convert(Varchar(100),dr_value,103) as Converted_Date from dr_tracking ;

What is the data of "yourcolumn" (the original column)?
- dr_value varchar(100)
  - dr_value - below is the value for that column
    04/26/2022 19:24:19

103 (dd/mm/yyyy) is the wrong format for that input

101 (mm/dd/yyyy) would be the right one

and from your last post you are trying to convert from a varchar to a datetime - so your convert would be

select Convert(datetime,dr_value,101) as Converted_Date from dr_tracking ;

sample example for you to check the differences in format - the first convert (103) fails, while the second works as expected

declare @Datex varchar(100) = '04/26/2022 19:24:19'
select Convert(datetime,@Datex,103) as date_103
select Convert(datetime,@Datex,101) as date_101

Thanks Frederico - I tried the below and getting the error below.

select Convert(datetime,dr_value,101) as Converted_Date from "users"."dr_tracking";

There was an error reading the results of the SQL statement.

The displayed results may be incorrect or incomplete.

Cannot convert '04/26/2022 19:24:19' to timestamp

SQLCODE=-157, ODBC 3 State="07006"

Line 1, column 1

select Convert(datetime,dr_value,101) as Converted_Date from "users"."dr_tracking"

that error looks like you are querying a Sybase database. is that correct?

and what driver are you using? vendor and version.

and... what are you doing with the returned value?
