Converting Text to Date

[KimTong via AccessMonster.com]

Hi,

Is anybody can tell me, how to convert from text data to Date?. I have a
table imported from Text file, text file only recognize text & number only.
One of the field (we call: TxtDate) they have is '20070515" (yyyymmdd) has to
be in date format. How can I convert it to our regular format (mm/dd/yy), so
I can calculate it?

I tried using Format(mid(TXTDate,5,2)&"/"mid(7,2)&"/"mid(3,2),"mm/dd/yy"). It
works, but I still can't use it as a date, so I can't put a parameter on it.

Thanks in advance

KF

Surround your Formatting work with the CDate() function. One problem with
CDate is that it will error out if given a Null value or something that can
not be evaluated as a date. I also highly recommend that your format has yyyy
as Access might guess wrong if the years far in the past or future like 1929
or 2033.

NewDate:Format(DateSerial(Left([FieldName],4),Mid(FieldName],5,2),Right(FieldName],2)),"mm/dd/yy")

IIF(
IsDate(Format(txtDate,"@@@@\/@@\/@@")),DateValue(Format(txtDate,"@@@@\/@@\/@@")),Null)

Format function always returns a string. So if you have a string that is
valid as a date, you can convert it with CDate or DateValue.

It works find using CDate or DateValue function, I can calculate that field.
But I still can't put a criteria, such as: >#6/1/07# on that field. Is anyone
can figure it out why?. Thanks...

You cannot use FORMAT if you want a field (column) that is a datetime field.
The format function converts the value into a string.

In a query #6/1/2007# is June 1st of 2007. Is that what you expect it to
be?

Perhaps you could post the SQL of the Query that doesn't work.

Yes. 6/1/07 means June 1st 2007, so I can't put any criteria on that field.
But I can calculate it, such as NewDate+10 etc...
