Access Expert Level 27
Description: Access Expert Level 27
Versions: This class was recorded with Microsoft Access 2013. The material is valid for Access 2007 up to 2021. Access has not changed that much over the years.
Pre-Requisites: Access Expert Level 26 recommended, as you should watch all of my classes in order. However, if you're skipping around, you should have at least completed the Beginner series and the first 3 or 4 levels of the Expert series where I start to cover functions.
Running Time: 1 Hour, 39 Minutes
Cost: $29.99

We have covered some of these functions in previous classes, however in this Comprehensive Guide to Access Functions we will cover those in a lot more detail, plus learn many new functions. Today's class is part 1 of 2 classes covering Date/Time functions. We will begin by learning some keyboard shortcut tricks to add automatic dates and times to our database during data entry. We'll spend some time learning more about the Date(), Time(), and Now() functions. We'll see how to use these functions to create default values in our tables and forms.

We'll learn more about the Format() function's parameters. We'll discuss the "2030" two-digit year problem and how to fix it. We'll learn how to create queries to show us:

- Records from today
- Records in the past or future
- Records on or not on a specific date
- Records between two dates
- Records outside of a date range
- Records in a specific list of dates, using the IN() function


We will learn a lot more about Date/Time Mathematics and the specifics of how to add, subtract, and deal with date and time values. We'll learn why the date 12/30/1899 is significant to Access and Excel users. We will learn how to use date math and the IIF() Function to create an Aged Accounts Receivable where we can see all of our past due, unpaid orders, and which ones are current, 30 days late, 60 days late, or more.

We will take extra special care to address date values that have times with them. These can often be a problem with many date calculations. You will learn how to show:

- Records from today with times in them
- Records between two dates with times
- Records from any specific date or range of dates with times
- Records for tomorrow or yesterday
- Birthdays from now until next week
- Orders less than one week old
- The number of days late an order is


Next we will learn how to work more with the mathematics of time values. You'll learn more about calculating hours and minutes as a fraction of a day. You'll learn how to calculate one hour in the future, or five minutes in the past. You'll use the CDate() function to convert other types of values into dates. You'll learn how to calculate someone's approximate age using date math. We'll work with a timesheet that has time values spanning midnight, allowing you to calculate the proper number of hours worked if someone started their shift at 11pm and ended at 6am the following day. You'll see how display 8.5 hours as 8:30, or 8h 30m. You'll see how to display 24:00 instead of 00:00, and format with one or two digits for hours and minutes.

This is the 27th class in the Access Expert series. This is the third class in my Comprehensive Function Guide series, and part 1 of 2 classes on Date/Time Functions. If you're serious about building quality databases with Access, don't miss out on this course. Of course, if you have any questions about whether or not this class is for you, please contact me.
