How to convert DateTime to UTC time using Apex Class?
Actually, there is not one, not two but four data types for datetime values in the Oracle database:. Actaully, the second example will lead to two conversions! Then the result is printed to the console - thus it must become a text again. The following example shows, how DATE literals look like. However, a time component cannot be passed; and the time of the constructed DATE instance will always be midnight.
We have seen that DATE instances contain a time component as well. When the session format mask does not contain a time component, that can lead to confusing behavior Now it's abvious - the two values are different and the query above cannot return rows. So, when only the date portion is needed within the application, it's good practive to consistently set the time component to midnight.
The above paragraphs describe general database behavior - this is true for all applications working with the Oracle database. So, this all applies to Application Express as well. Application Express just contains some declarative settings in order to set the format masks and a bit of additional functionality.
For every application, we can set the application default format masks. If nothing is provided, the Oracle database defaults will apply. But APEX allows to set explicit format masks, for instancer in report columns or page items. These format masks supersede the default settings.
It's being used within the application builder at several places. The language is determined by the application language and messages are available for all languages which the Application Builder has been translated to. Of course, the translation must be installed as well. If the developer provided an explicit format mask with the page item, it will be used.
If not, the above mentioned application default format masks will be used - and if we don't even have these, database defaults apply. An example: We have a form item of the date picker type. It's based on a DATE column in a table. We have provided an explicit format mask: DD. Date Picker page item with a format mask.
For these conversions, format masks are important. The same rules apply. These topics will be covered in a future blog posting - until then: have fun while working with Application Express. Application Express: tips, tricks and best practice.Register and Participate in Oracle's online communities.

It can be a complicated thing to deal with, at times, for SQL Server developers. Suppose you have a Product table with a column timestamp.
It creates a timestamp for each customer order. You might face the following issues with it. We do face many such scenarios when we do not have date format as per our requirement. We cannot change table properties to satisfy each requirement. In this case, we need to use the built-in-functions in SQL Server to give the required date format.
As highlighted earlier, we might need to format a date in different formats as per our requirements. We can see various date formats in the following table. You can keep this table handy for reference purpose in the format of Date Time columns. Datetime format in YY. Datetime format in [YYYY. Datetime format in DD. YY format Standard : German. In the table, we can see various formats to SQL convert date as per your requirements.
In the following table, you can see all SQL date formats together. Suppose we have a requirement to add 1 month to current date. Interval: We can specify an interval that needs to be added in the specified date. We can have values such as year, quarter, month, day, week, hour, minute etc.
Number: It specifies the number of the interval to add.
For example, if we have specified interval as Month and Number as 2, it means 2 months needs to be added in date. We can use the format code to get output in this format. Conclusion In this article, we explored various SQL convert date formats. It allows getting a date in required format with Covert function easily. You can use this article to take a reference for all date formats and use in your queries. Print Existingdate. Author Recent Posts. Rajendra Gupta.

Are you looking for a way to convert the result to an Interval Type? Ah, then you want what Alex said.
Er, no. You might want an interval as mentioned above, otherwise you're working in number-of-days.
I can't use an interval data type. Thanks for helping though. Ok the last option was really what I wanted to avoid. But I'll try the option with the timestamps. Great solution! But I've tried it also with transformation of the two date-types to timestamps and then the difference comes out in the format needed. It seems to be the easiest way. Thanks again! Why exactly do you want to do this? What will you do with the result?
You do know that the result of subtracting two timestamps is an interval datatype, the same type you earlier said you couldn't use, right? I want to track down run times of certains procs. This runtime information is not something I can use in the interval data type.
But I also admit, that I am not so familiar with this type.The datetime format template is a template that describes the format of datetime data stored in a character string. The template does not change the internal representation of the value in the Database. When you convert a character string into a date, the template determines how Oracle OLAP interprets the string.
In order to assign a datetime format template to a definition, the definition must be the one most recently defined or considered during the current session. An expression composed of one or more datetime format elements that specifies the format for entering and displaying the values of the current object.
See Table"Datetime Format Elements" for the elements that you can specify in the template. Keep the following points in mind when creating a template:.
For input format models, format items cannot appear twice, and format items that represent similar information cannot be combined. When template is omitted, any existing date format template for the current definition is deleted and the default datetime format template is used. See "Default Datetime Format Template"for a discussion of the default datetime format template. Table Datetime Format Elements. If the last 2 digits of a 4-digit year are between 01 and 99 inclusivethen the century is one greater than the first 2 digits of that year.
If the last 2 digits of a 4-digit year are 00, then the century is the same as the first 2 digits of that year. Name of day, padded with blanks to display width of the widest name of day in the date language used for this element. Month yyyy '. Restriction: You can specify this format only with the TS element, separated by white space. Returns a value in the short date format. Fractional seconds; no radix character is printed use the X format element to add the radix character.
Use the numbers 1 to 9 after FF to specify the number of digits in the fractional second portion of the datetime value returned. If you do not specify a digit, then Oracle Database uses the precision specified for the datetime data type or the data type's default precision.
