A current query is a SELECT statement that extracts and operates on the current rows of a table:

  • For a transaction-time table, current queries operate only on open rows.
  • For a valid-time table, current queries operate only on rows with valid-time periods that overlap the current time.
  • For bitemporal tables, current queries operate only on rows that are both open in the transaction-time dimension an current in the valid-time dimension.

A current query produces a nontemporal table as a result set.
