The INTERVAL data type stores a value that represents a span of time. INTERVAL types are divided into two classes: year-month intervals and day-time intervals. A year-month interval can represent a span of years and months, and a day-time interval can represent a span of days, hours, minutes, seconds, and fractions of a second.
Oracle CHAR comparison uses blank-padded comparison semantics, similar to the way Informix Dynamic Server compares CHAR and VARCHAR data. If two values have different lengths, Oracle adds blanks at the end of the shorter value, until the two values are the same length. Oracle then compares the values, character by character, up to the first character that differs. So two values that are.
In Informix INTERVAL MINUTE TO MINUTE data type stores a time interval in minutes. As a data type it just stores an integer value, but when you cast any interval value (INTERVAL DAY TO SECOND i.e.) to ::INTERVAL MINUTE TO MINUTE, you get the total number of minutes in the interval.In Informix INTERVAL SECOND TO SECOND data type stores a time interval in seconds. As a data type it just stores an integer value, but the most interesting thing about this data type is that when you cast any interval value (INTERVAL DAY TO SECOND i.e.) to ::INTERVAL SECOND TO SECOND, you get the total number of seconds in the interval.Informix 12 averaged 54 percent less than for use of Oracle Database 12c with RAC. Figure 3 illustrates these results. Figure 3: Three-Year Costs for Use of Informix 12 versus Oracle Database 12c and Real Application Clusters for Centralized UNIX Server Deployments In x86 server installations in these and other industries, three-year costs for use of Informix 12 averaged 28 percent less.
