MS SQL Query to search between dates

I want to write a query where I can serarch from a table based on date column, however I do not want pass any date.  THe requirement is to always search today's data or yesteday's date betweenn 0000 and 2359 hrs.
For example:

select * from Table1 where entryDate>=todays date 0000 and <todays's date 2359.

for todays's date can I use sysdate or something  like that instead of passing a value from the program ?

Yes you can use

select * from Table1 where entryDate>=getdate() and entryDate<getdate()

To search the entire day range you could do something like this.


WHERE entryDate >= DATEADD(d,0,DATEDIFF(d,0,getdate())) AND entryDate < DATEADD(d,0,DATEDIFF(d,-1,getdate()))

I think you mean:

where entryDate >= dateadd(dd,0, datediff(dd,0, getDate()))
 and entryDate < dateadd(dd,1, datediff(dd,0, getDate()))
