Writing SQL statement in sqlcmd to hide the milliseconds for column type of time
If you just need to remove the nano-seconds for display purposes you could convert the time value to a string using the below which will give you the format you desire:

SELECT ID, CONVERT(NVARCHAR, EXPIRE_TIME, 108) AS EXPIRE_TIME FROM TESTTABLE;


However, if you do decide to do this and then decide you need to perform calculations on the information, you would need to cast it back to a time value; which would give you the nano-seconds again but they would be set to zeros.

Alternatively, you could handle the formatting of the data in the object that is consuming it; for instance a SSRS report (which has the Format() function) or in an ASP.NET Web Form (which has a multitude of ways to handle this). It really depends on what your ultimate goal is that you want to achieve.

I hope this helps you.
