Question : DateDiff Minute GetDate Between C# vs SQL

I've been using the following C#/SQL combo to get a solution. It works as-is but I would like to have a pure-SQL solution if possible.

[C#/SQL Combo]
string strCurrentTimeOnly = DateTime.Now.ToShortTimeString(); // 10:17 AM
string strDayofWeek = DateTime.Now.DayOfWeek.ToString(); // Thursday
                   
string sql = " Select * from tbl_Users where col3 = 'True' " +
" and DateDiff(n, col_TimeOnly, '" + strCurrentTimeOnly + "') between 1 and 1 " +
" Or col_DayOfWeek = '" + strDayOfWeek + "')";

[SQL using GetDate()]
" Select * from tbl_Users where col3 = 'True' " +
" and DateDiff(minute, col_TimeOnly, GetDate()) between 1 and 1 " +
" Or col_DayOfWeek = '" + strDayOfWeek + "')";

The SQL above returns nothing... I think the problem is GetDate() represents datetime and not just time only ....

Help...

Answer : DateDiff Minute GetDate Between C# vs SQL

So, now it is a datetime in SQL, can now do a similar thing:

Select *
from tbl_Users
where col3 = '1'
and dateDiff(mm, col_TimeOnly, getdate()) = 1


not sure what the "between" is trying to achieve, so the = 1 above might need to be different...
