If you find TIMESTAMP() too restrictive for your needs, see TIMESTAMPADD() Examples. This manual describes the sample database schemas available with Oracle Database and used in some Oracle documentation and curriculum examples. This function also accepts units such as days, months, years etc. You can use the TIMESTAMPADD() function to add a specified unit to a date or datetime value. However, the TIMESTAMP() function may still be your preferred function in certain cases, for example if you want to add a time value to the current date. If you want a timestamp that uses the current date, you might be more interested in functions such as NOW(), CURDATE(), and possibly even SYSDATE() (for the difference, see SYSDATE() vs NOW()).
You can subtract the second argument from the first, simply by prefixing the second value with a minus sign. In this case, we use it to add a large number of hours to a date value. Wide-column store: These databases store information in columns, enabling users to access only the specific columns they need without allocating additional memory on irrelevant data. It could also be used to represent elapsed time. An example of a document-oriented database is MongoDB, the database component of the MEAN stack. This is because it’s not just limited to representing the time of day.
The time data type can have a range from -838:59:59 to 838:59:59. As mentioned, the second one gets added to the first. When you do this, the result will also include that part. You can also include a fractional seconds part up to microseconds (6 digits). Example 2 – Provide a ‘datetime’ ArgumentĪnd here’s an example using a datetime expression. So the result is a datetime value regardless of whether our argument was a date or datetime expression. In this example I provide a date expression. If you provide two arguments, expr2 is added to expr1 and the result is a datetime value. The second argument ( expr2) is a time expression. The first argument ( expr and expr1) is a date or datetime expression.

Helping to manage the sales process by organizing sales activities, right down to the last detail, and even monitoring future, current and past sales activities with embedded forecasts and pipeline reporting GoldMine is yet another example of a database solution used to better the corporate philosophy. You can use either of these two forms: TIMESTAMP(expr) If you provide two, it adds the second one to the first and returns the result. By voting up you can indicate which examples are most useful and appropriate. In MySQL, the TIMESTAMP() function returns a datetime value based on the argument/s passed in. Here are the examples of the csharp api class (, ) taken from open source projects.
