Answer 1

Most versions of SQL have some way of getting the current date. For instance:

where date >= cast(CURRENT_TIMESTAMP as date)
where date >= cast(getdate() as date)
where date >= date(now())
where date >= trunc(date)

The specific syntax you need depends on the database you are using.

EDIT:

The first or second versions should work with SQL Server Express.

SQL will consider your date "11/08/2014" in mm/dd/yyyy format by default. You would need to rearrange the month before the date like "08/11/2014" before making the comparison. Below code will get you the required results:

SELECT CONVERT(VARCHAR(20),CAST(Time AS DATE),120)
FROM Table
WHERE CONVERT(VARCHAR(20),CAST(Time AS DATE),120)>=CONVERT(VARCHAR(20),GETDATE(),120)
