A record of random access Recordset

Assuming that this data table has a unique ID field, and at least one record. Random access method in which a record is very simple, can be divided into four steps:
1, to obtain records of the total number of n.
2, all the ID number stored in an array
3, generates a random number less than n, m
4, removed from the array of the first m-ID, query data table, record data obtained.
Here is some code:

set conn = Server.CreateObject ('ADODB.Connection')
conn.open ''

For SQL Server, there are more efficient ways. Such as the design of two stored procedures. I am here just to clarify some ideas, and hope that this idea can also be used in Access and SQL Server.
