Oracle CURRENT_DATE Function
 
01:54
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago). For more information about the Oracle CURRENT_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

Oracle TO_TIMESTAMP_TZ Function
 
01:43
https://www.databasestar.com/oracle-timezone-functions/ The Oracle TO_TIMESTAMP_TZ function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP WITH TIME ZONE value. A TIMESTAMP WITH TIME ZONE value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, and seconds - A time zone, which is the number of hours and minutes difference from GMT This is a useful data type because it allows you to store dates in different time zones, and allow users in other time zones to see the data in a way that makes sense to them. The time zone part is the difference from GMT. This means that a “+7:00” is 7 hours ahead of GMT (e.g. Bangkok) and “-5:00” is 5 hours behind GMT (e.g. US Eastern Standard Time). The syntax of the TO_TIMESTAMP_TZ function is: TO_TIMESTAMP_TZ ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names.

How to Use MySQL Date and Time Functions
 
02:21
Follow this step by step easy tutorial to learn how to use MySQL date and time functions and see how to modify the time formats. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.facebook.com/howtechtv - join us on facebook https://plus.google.com/103440382717658277879 - our group in Google+ There are various functions which can be used for calculating the date and time in MySQL but for the purpose of this tutorial we will use 3 primary functions for date and time each. For this tutorial, we will be using SQL YOG as an instance of MySQL.  Step 1- Current Date Let's start with MySQL date functions. For that write the following query: select curdate(); and press F5 to execute. It will show the current date of the system. Curdate is a short form of current date. Step 2-Changing date format Now if we want to view the date in a specific format, we can use a function called the date_format(). Write "date_format" function in a similar pattern as before, but this time inside the parentheses, we will write the date within single quotation marks and then specify the required format in single quotations after a comma. Here we are using W for week, M for Month and Y for years which are implicit format specified in the MySQL environment, and used with a percentage sign. The actual query would be: select date_format('2013-04-18','%W %M %Y'); Step 3- Viewing Name of the Day In MySQL date functions library, there is a method which can return the day name, when given the date as its perimeter. It is called "dayname" function. To use that, write dayname(), following the "select" keyword, and specify the date within single quotes inside the parenthesis. The query would be: select dayname('1998-04-25'); Step 4- Time Functions Now let's move on to mysql time functions First of all let's find out the current time. For that, we will write curtime(),which stands for the current time, and write the query in the same way as we did for the current date. Hence the query would be: select curtime(); Step 5- Changing time format Now let's see how we can change the format of the output. For that, use the time_format() function, as we did for the date format. Write the following query in the editor: select time_format('14:28:18','%h : %i : %s'); Over here, h, i and s are used for hours, minutes and seconds respectively. Step 6- Changing Time to Seconds In MyQL time functions library, there are various functions related to time. One of them which is widely used by programmers is the time_to_sec() function. This method changes the given time to seconds. To use this, write time_to_sec() and specify the time inside the parentheses within single quotes. In the Query Editor, write: select time_to_sec('14:28:18'); When we execute the query, we can see that the time being displayed is in seconds. Step 7- Date along with Time Lastly, to display the current date and time altogether, we can use now() function along with the select keyword. Write: select now(); in the query editor and execute it. And this was all about MySQL date & time functions.
Hibernate Tip: How to map a java.util.Date
 
03:36
Get more recipes like this one in my new book Hibernate Tips: More than 70 solutions to common Hibernate problems: https://goo.gl/XfywNk JPA and Hibernate offer a standard mapping for java.util.Date that stores it as a timestamp with nanoseconds. That’s OK as a default, but as always, it doesn’t fit all use cases. In this video, I want to show you how you can easily customize this mapping.
