The Most Useful Date and Time Functions
Working with dates in Oracle PLSQL.get for and and
Please keep up the Good Work. All the Best. Thank you using above database queries i will solve db related problems in my many project. Describe the view and see the columns.. Use the column name to get the details. I have a requirement. I have 5 attribute columns corresponding 5 days of the week from Monday to Friday.
Learn more about time interval datatypes. Before version 9i, Oracle had no built-in way to record the passage of time. The DATE datatype records an individual moment in time; but to express a quantity of time i. For instance, 60 seconds to the minute, 60 minutes to the hour, 24 hours in a day—these are all awkward numbers to deal with in a number system based on decimals. There are defaults for the precision values: two digits for the year and day, and six digits for fractions of seconds.
The vast majority of problems people encounter are because of a misunderstanding about how dates are stored in the database. What you see on screen from a query is what's in the database right? Well actually, that is often not the case. In the process, they often miss out very important information that can confuse you if you are not careful. So both columns contain the same value right?

DATE is the datatype that we are all familiar with when we think about representing date and time values. It has the ability to store the month, day, year, century, hours, minutes, and seconds. It is typically good for representing data for when something has happened or should happen in the future. The problem with the DATE datatype is its' granularity when trying to determine a time interval between two events when the events happen within a second of each other. You can add and subtract number constants as well as other dates from dates.
