LAST_DAYfunction. DB2 and HSQLDB also have a similar function with some differences in data type of result.SYSDATEnow rounds fractional seconds down for better compatibility with Oracle (see Oracle DATE type: milliseconds (second fractions) rounded in H2 but truncated in Oracle #3705).TIMEvalues for every hour (TIME '00:00:00',TIME '01:00:00', …) andTINYINTvalues are introduced. Their classes are initialized by regular JVMs only when these data types are actually used by application, it means this small amount of memory will not be wasted when these data types aren't used.
