How do you access sysdate and current time in stored procedure SQL server

I have stored procedure which runs wvery hour. However every hour I need to dynam,ixally change date/time,. I need two cases
a. Run query for previous day to concompass the whole day
select * from Table where dateTime>=(sysdate-1):0000 and dateTime=(sysdate-1):2359

b. I need a query which looks for anything for the past one hour for today

select * from Table where dateTime>=sysdate-1:currentime and dateTime<=sysdate:currentime -1  (past one hour)

back 1 hour:
select * from tablename
where datefield >= dateadd(hour, -1, getdate()) 
and datefield < getdate()

a.
select * from tablename

and datefield < cast(convert(varchar(10), getdate(), 101) as datetime)

b.

in sql server the date+time (aka now) is available from GETDATE()


select * from Table 
  where dateTime>=dateadd(day, -1, getdate())
    and dateTime<=dateadd(hour,-1, getdate())

Improve Your Query Performance Tuning

In this FREE six-day email course, you'll learn from Janis Griffin, Database Performance Evangelist. She'll teach 12 steps that you can use to optimize your queries as much as possible and see measurable results in your work. Get started today!

If you happen to be using SQL Server 2008, you can make use of the new Date datatype to accept the dateadd(day, -1, getdate()) value from angelIII's solution for the "yesterday" portion of the problem and then match based upon your dates being between that value and that value + 1.
If you are not on SS2008, you can make use of the fact that the dates are integers and the times are fractions in a double datatype.  (See SQL_1 below)
If you want the process to check for exactly and precisely datetimes during the hour immediately preceding the execution, angelIII's solution is your answer for the second half of the problem.

SQL_1:
 
DECLARE @Yesterday AS DateTime;
DECLARE @ToDay AS INT;
DECLARE @INTTIME AS INT;
DECLARE @LastHour AS Datetime;
DECLARE @ThisHour AS Datetime;
 
 
 
SET @Yesterday = CAST(CAST(GETDATE() AS INT) AS DATETIME);
SET @ToDay = CAST(Cast(GETDATE() AS INT) AS DATETIME
 
SELECT @ThisHour = 
       CAST(CONVERT(VARCHAR(02), JustTime, 108) AS INT)FROM
(SELECT GETDATE() - CAST(INTDATE AS DATETIME) AS JustTime,
        INTDATE
FROM
(SELECT CAST(GetDate() AS INT) AS INTDATE
) X
) Y;
 
SET @LastHour = @ThisHour - 1;
 
 
SELECT * 
FROM Table 
WHERE CAST(DateTimeColmun as INT) BETWEEN @YESTERDAY AND (@YESTERDAY + 1);
 
SELECT *
FROM Table
WHERE DateTimeColmun >= (@Today + @LastHour) 
  AND DateTimeColumn <  (@Today + @ThisHour)

did you try my first post?

select * from tablename
where datefield >= cast(convert(varchar(10), dateadd(d, -1, getdate(), 101)  as datetime)
and datefield < cast(convert(varchar(10), getdate(), 101) as datetime)

chap, that did not work. It gave me following error:
Server: Msg 174, Level 15, State 1, Line 21
The dateadd function requires 3 arguments.

there is some () misplaced..

select * from tablename
where datefield >= convert(datetime, convert(varchar(10), dateadd(d, -1, getdate()), 120), 120)
and datefield < getdate()

amgelll your qyery seems to be working ok, how can modify this for just looking back for past one hour.

Chap, your query is returning only rows for past one day, not for today
