Multi Value Fields Upload Images   Link   Email

Hi Richard,

Just finished Make Table Query (3).  Not that I have a field like this, but if I was fixing a Table with a Long Text field with the Allow Append set to "Yes" and you need to keep all the revisions how do you create a table with the revisions as separate records?

It's very difficult to answer based on "What if?".  I could think of multiple scenarios where this might happen.

In any case you would just have to treat that Long Text field by itself. Then using the String functions break up the data already in the LT field into it's proper table structure.  One of the reasons the Multi-Value Field is considered Evil is due to the difficulty of making it right in the future once you learn proper structure.

In most cases someone who has used a Multi-Value Field has set up their DB incorrectly because they didn't understand relationships.  You are learning correctly so you won't fall in to that mess. :)

In the newest TechHelp video Normalizing Data Richard covers multiple examples of breaking up that type of data.

Do yourself a favor and consider becoming a TH member.  You won't regret it. There is literally tons of info, especially in the extended cuts, that is not covered or greatly expands on what is covered in the courses.
