Hello,

I have a field in Access that has the time and date shown like this: 1/10/2011 10:14.  I would like to remove the time and only show the date.  What query can I create to accomplish this?

If the data type is Date:


UPDATE [SomeTable]
SET [SomeColumn] = Int([SomeColumn])

Open in new window



If the data type is Text, and if the time is always at the end of the string:


UPDATE [SomeTable]
SET [SomeColumn] = Left([SomeColumn], InStrRev([SomeColumn], " ") - 1)

Open in new window

update tablex
set [datefield]=datevalue([datefield])

Rey,

In this case, Int and DateValue will yield the same result.  I recommended Int instead of DateValue because, if I remember gustav correctly, DateValue is slow as molasses :)

To matthewspatrick:
I tried the expression but it said Syntax Error in query expression.
I'm a novice Access user, so can you give me more instruction.  Thanks!
