Convert Lont Integer into Date and Time

[Guest]

Hello:

I am importing file that has date and time fields in the long integer format
as follows:

Date_occurred Time_occurred
20051109 04562
20051109 132640

Can I do the conversion in the import specification? I tried to change data
type to date/time and I get Type conversion failure in ImportErrors Table.

Can I convert in a query by using a conversion function? What function
should I use?

Would appreciate your help.

Hi, Danka.

Can I do the conversion in the import specification?
No.

I tried to change data
type to date/time and I get Type conversion failure in ImportErrors Table.

That's why you can't convert with the import specification. These numbers
don't correspond to any valid date or time format.

Can I convert in a query by using a conversion function?

You'll need several VBA functions to accomplish this if that's what your
data looks like.

What function
should I use?

First, import the data into a table, but import these Long data types as
Text data types. Next, create two more fields in this table: one named
DateOccurred and the other named TimeOccurred, both as Date/Time data types.
Create an update query that assigns dates to the DateOccurred field and times
to the TimeOccurred field, based on the corresponding text fields. Try:

UPDATE tblMyTable
SET DateOccurred = CDate(MID(Date_occurred, 1, 4) & "/" & MID(Date_occurred,
5, 2) & "/" & MID(Date_occurred, 7, 2)),
TimeOccurred = CDate(Format(IIF((LEN(Time_occurred) < 6), Time_occurred &
"0", Time_occurred), "00:00:00"))

.. . . where tblMyTable is the name of the table. And be advised that a
Date/Time data type can hold both the Date_occurred and Time_occurred values
in one field, so you don't need two fields.

HTH.

Hello:

Thank you very much for answering my questions.

Your solution works and returns the answer in the following format for the
date:
20051109 11/9/2005
20051109 11/9/2005

I also tried the following expression:
Left([date_occurred],4) & "/" & Mid([date_occurred],5,2) & "/" & Mid
([date_occurred],7,2)

Thank you very much for your response.
