INTERVAL data type

    XMLWordPrintable

Details

    Description

      Currently INTERVAL literals can appear in context of the DATE_ADD function and the operator +.
      For example:

      SELECT DATE_ADD(OrderDate,INTERVAL 30 DAY) AS OrderPayDate FROM Orders
      		 
      SELECT OrderDate + INTERVAL 30 DAY AS OrderParDate FROM Orders;
      		 
      SELECT INTERVAL 30 DAY + OrderDate AS OrderParDate FROM Orders;

      We will change INTERVAL from a DATE_ADD and + specific syntax to a full-functional data type, so intervals can appear in all context where a regular data type can, including:

      • INTERVAL table fields
      • INTERVAL stored routine variables, parameters, function return values
      • Hybrid built-in functions and operators, such as COALESCE, IF, CASE, LEAST, GREATEST.
      • MIN and MAX aggregate functions
