Depends on what you are trying to do - are we talking about a WHERE clause? If so, what data are you comparing? Or are we talking about find all records with a date since midnight?

Try this for SQL server,

SQL

SELECT yourField FROM yourTable WHERE yourDateField = GETDATE();

or for MySql

SQL

SELECT yourField FROM yourTable WHERE yourDateField = NOW();

Hope this helps

The only problem with that is that if the field is DateTime rather than just Date, it doesn't work...:laugh:

The OP specified a Date field. Your answer would be more fail safe.

If you are using SQL2008, you can convert to the Date datatype
For example in the AdventureWorks Database

SQL

SELECT  *
FROM    Sales.SalesOrderHeader
WHERE   CAST(OrderDate AS DATE) = CAST(GETDATE() AS DATE)

The safest way is to use DatePart:

WHERE DATEPART(year, demodate)=DATEPART(year, GETDATE()) AND DATEPART(dy, demodate)=DATEPART(dy, GETDATE())

This returns only records where the year and day of year are the same - be aware that if you should read GETDATE once, and store it, as otherwise is may cause intermittent errors around new year!
