Backup of SQL Server databases from within Microsoft Access

via Tony's Microsoft Access Blog by Tony on 12/16/12

WARNING:  Some of the following instructions may not be best practice.    This is a personal database so I can afford to take some shortcuts and not do thorough research.  If you do use these tips and sample code in production check back in a week and a month to see if there are any changes or comments.

Objective

I wanted to create a method of backing up a personal SQL Server database from within Access.   In a production environment you'd have tasks which ran on a regular basis, i.e. at midnight or whatever, that would do this.  But here I might update some records every few days and wanted to do this on my schedule.
Note that, as the names of the stored procedures indicate, I will be modifying these as I add more functionality such as database checks, log truncation, etc.

Answer: If you've tried setting your tables as hidden objects and the users are still able to find them, you can always set your tables up as system tables. Inside of your Access database, there are several system tables that even you can't see. These tables are used internally by the Access database.

Bind combo box to primary key but display a description field in Access

Question: In Access 2003/XP/2000/97, I've set up a table that contains an autonumber field as the primary key and a description field. I want to be able to create a combo box that displays the description, but stores the primary key. How do I set up the combo box?
Answer: Quite often the primary key value can mean nothing to the user. Instead, there is a description field in the table that relays the meaning of the record. In Access you can link a combo box to the primary key, but display the description in the combo box itself.
To do this, first create a combo box object. Right-click on the combo box and select Properties from the popup menu.

DateDiff Function

In Access, the DateDiff function returns the difference between two date values, based on the interval specified.

interval is the interval of time to use to calculate the difference between date1 and date2. Below is a list of valid interval values.

View only records with uppercase letters for a certain field in Access

Question: In Access 2003/XP/2000/97, if I wanted to view only the records with Uppercase letters for a certain field, how would I do it?

Answer: Access was built to be case-INSENSITIVE, but we can always use the ASC function to determine upper vs lower case.

Calculate and format an elapsed time value in Access

Question: In Access 2003/XP/2000/97, how do I format a time on a report so it appears as elapsed hours and minutes?
For example, 27 hours and 31 minutes appears as 27:31. I can do this for values up to 24 hours. But for anything over 24 hours, the full day(s) are dropped off.
Answer: A "elapsed time" is usually calculated by taking the difference between two dates. So, you will need to store the "from" and "to" dates separately and then calculate the elapsed time.

upperbound is the highest value that the random number can be.
lowerbound is the lowest value that the random number can be.
