Query to edit date format

Preview
does anyone know how to edit for date format? For example, when I pull in a text file, one of the field is date and it would be in yyyymmdd, however sometimes if the user doest create the text file correctly then the date would be entered in as mmddyyyy or some other incorrect date format. So what I want to do is, once the file is pulled into a table I want to create a query to catch if the format is NOT in yyyymmdd. Is there a way to do this? maybe a function or something? please assist.
 

number to Date format

Preview
I have a number field which has date information in it. ex - 20110112 YYYYMMDD in that format. Don't ask why they didn't just make it a date format.

Right now a date conversion table is used. So when referencing that field it does a join on the number date and return the date format. Two field table. First column is 'number date format' and the second is 'return date format'. The table is manually kept up each year.

anywho,

Just trying to figure out how to format that into a Date format so that I can perform date function on it using sql so that I don't have to maintain the date conversion table
 

Calculating length of stay in form using Datediff

Preview
I'm designing a form and I want to calculate how long our hotel tenants stay. So I have the form open and I am in the property sheet under the data tab. I am using the expression builder, and I see DateDiff has this format: DateDiff (interval, date1, date2, firstweekday, firstweek)

I put in this: DateDiff("d",([End Date],Date())-[Start Date])

I'm getting a wrong number of arguments error. I was also getting another error last night related to the "d" portion of the equation. Obviously I am pretty new and unsophisticated at this stuff so I thought I would check with the experts here for some

Date Conversion

I am trying to convert a date in the text format to Date format using the CDate() function in a sql query in MS Access, which is working fine. But when I try to export the results to a an excel file, the date is being displayed as text field again.

How do I correctly convert & format the text values and then export the values as Date (Numeric) in to Excel?

And the date is in the UK format 'dd/mm/y'
 

Changing date format for optional field

Preview
I need to do some date calculations on an optional date field that is current in YYYYMMDD text format.

I can get the date to format by using:
DateValue(Format(CLng([Date]),"0000-00-00"))
However, it returns an #Error if the field is blank.

I'm trying to write in the builder to leave the field blank if it is currently blank:
iif(IsNull[Date],"",(DateValue(Format(CLng([Date]),"0000-00-00")))
 

CDate in my append query

Preview
Importing individual records from a massive database. As I import, I would like to change the format on the fly of the dates, which are stored as text in DB1, as to store them in date format in DB2, my new DB.
I have seen lots of info on the CDate function but cant figure out where to place it, and how to use it. My query works great, but I need to be able to use this 'date'

YYYYMMDD is the format in DB1 'TEXT" field

I could care less what format I get out of it
