[AccessD] Every 100th record

    If there are gaps in the sequential values pertaining to the primary key field, the following could be considered (T_Data is the name of table and ID is the name of primary key).

SELECT T_Data.*
FROM T_Data
WHERE (Select Count(*) From T_Data T1 Where T1.ID <=  T_Data.ID) Mod 100 = 0;

  If this table has a sequentially numbered Identity field (if that's the
  correct name for the SQL version of an AutoNumber) then just run a select
  query with the condition (Mod 100 = 0) on the Identity field.
