  • If no temporal qualifiers are used in the FROM clause, the default for valid-time tables is to qualify all rows in the table, regardless of validity.
  • If temporal qualifiers are used in the FROM clause, the valid-time start and end columns are not returned in the results.
  • BETWEEN ... AND, FROM TO, and CONTAINED IN all qualify queries of temporal tables according to a period of time. Any table rows that were valid at any time during the specified period (or immediately after it in the case of BETWEEN ... AND) are qualified for the query. The differences in the three temporal qualifiers are subtle, but allow you to define your query to qualify a precise set of rows.
