Search and you should find. Jun 20, 2019 · So both functions return the difference in days, however one result is positive and the other negative. This is because DATEDIFF () subtracts the second date from the first, whereas TIMESTAMPDIFF () subtracts the first date from the second. Example 2 – Changing the Unit Db2 SUBSTRING() function examples. Let’s take some examples of using the SUBSTRING() function to understand it better. 1) Using Db2 SUBSTRING() function to extract a substring example. This example uses the SUBSTRING() function to extract a substring whose length is 3 starting from the first character of the source string: You could use for example as an indication of "age" of ticket - julian_day function like this: db2 select julian_day(current timestamp)-julian_day(change_time) and - if the result is 0 meaning change occured today - use midnight_seconds(). Other approach would be to write UDF to calculate difference in seconds between two timestamps. Jan M.

This function takes in two parameters. The first parameter is a numeric value indicating the unit in which you wish to receive the results in; the values must be one of the following. Db2 TIME Literals. Time literals must conform to the following rules: Time literals cannot have leading blanks but can have trailing blanks. The leading zeros of the hour parts can be skipped, for example, 01:00:00 is the same as 1:00:00. The second part of a time literal can be omitted. For example, 01:00:00 is the same as 01:00. IBM DB2 provides a generalized timestamp difference function (TIMESTAMPDIFF) but it simplifies the calculation by always assuming a 365-day year, 52-week year, and 30-day month.
