Convert query from Oracle to SQL server

Question

I want to convert below Oracle query into SQL server environment-

select to_date(substr(to_char(col1, 'YYYYMMDD HH24MISS),1,8), 'YYYYMMDD') from tab;

From the above query i want to convert it into first time in Date format and then second time Time format . It means two times i want this query while above one in Date format .

Answer 1

This is not even how I would do this in Oracle. This is converting the date/time value to a date, with no time component. In SQL Server:

select cast(col1 as date)
from tab;

In Oracle:

select trunc(col1)
from tab;
