SELECT pk FROM TABLE ORDER BY Rnd(pk) asc

And it\'s working f

    You just need to "salt" your random generator:

    Rs.Source = "SELECT pk FROM TABLE ORDER BY Rnd(-Timer() * [pk]) Asc"

    Finally it seems that i found a solution.

    Following what's written in the above link

    Here is a very simple way of selecting random records from an Access database:

    SELECT TOP 5 * FROM [tableName] ORDER BY rnd(INT(NOW*id)-NOW*id)

    The only prerequisite is that you have an AutoNumber Id column. It should also be noted that although this generates a random set of records, they are not truely random in a mathematical sense, but should be sufficiently random for most uses.

    This method of selecting records also works in sql server, but you have to change rnd to rand.

    If you find a better solution, i'll be pleased to mark it as the good one. In the mean time, i'll leave this here. hoping that this will help somebody else. (You won't believe it but it took me some time to find it)
