You mention database but have Excel as a Topic Area.  Can I assume Access not Excel?

There is an article here on the site that talks about querying random rows from Access:

You would use the RND() function in VBA to generate a number:

https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/rnd-function

 If the video's are named numerically, then you could just choose a video based on that.  If not, then you'd need to load them in some type of a list (i.e. an array or collection), then the nth video from that list.

Thanks, Ill give that a go and get back to you if I have any issues if thats ok?  R
John TsioumprisSoftware & Systems EngineerCommented:
The Rnd() funtion will generate a random number between [0...1] e.g
0,301948
0,2895625
0,5795186
0,533424
0,7055475
Suppose that your video links are stored in a table you could multiply this random number and get an integer pointer
E.g. your table has 100 entries
multiply it it with the 1st result
will give you
100* 0,301948 = 30,1948...convert it to integer you get it the 30th record
So simply by multiplying the Recordcount and the rnd() will give you a random selection of the video link

If you are using Access you might be able to do this with a query, something like this.

SELECT TOP 1 [VideoLinkField] FROM [MyTable] ORDER BY INT(Rnd(Now())*10000)

Thankyou, Ill give that a go :-)

I guess the question for you is how you have these videos are indexed/cataloged; are they in a table or are they just out on disk?

On a disk at the moment but they will be in a table.  I have a few in a table to play with at the mo

If you wish to pick one random ID from the table, you can use DLookup this way:

Criteria = "[ID] = (Select top 1 ID From [YourTable] WHERE (RandomRowNumber(CStr([ID])) <> RandomRowNumber('',True))  Order By RandomRowNumber(CStr([ID])))"
RandomID = DLookup("[ID]", "[YourTable]", Criteria)

Open in new window

The RandomRowNumber function is from my article and demo:
