## How do you check if the year is a leap year in SQL?

You can do this by adding 31 (DATEADD(YEAR,@YEAR-1900,0) results for Jan 01 of that year). Using EOMONTH finds the last day of the month. Using DAY function find out day value. If it is 29, it is a leap year otherwise it is non Leap year.

## How do I select year from date in SQL?

If you use SQL Server, you can use the YEAR() or DATEPART() function to extract the year from a date. Similar to SQL Server, MySQL also supports the YEAR() function to return the year from a date.

## How is leap year calculated?

To check if a year is a leap year, divide the year by 4. If it is fully divisible by 4, it is a leap year. For example, the year 2016 is divisible 4, so it is a leap year, whereas, 2015 is not. However, Century years like 300, 700, 1900, 2000 need to be divided by 400 to check whether they are leap years or not.

## How do I get the current date in DB2 query?

To get the current date, time, and timestamp using SQL, reference the appropriate DB2 registers:

- SELECT current date FROM sysibm.sysdummy1 SELECT current time FROM sysibm.sysdummy1 SELECT current timestamp FROM sysibm.sysdummy1.
- VALUES current date VALUES current time VALUES current timestamp.

## Is there a SQL Server Function to determine a leap year?

However, you needn’t bother yourself about leap year rules… you can let the SQL Server engine do the work for you! The following scalar function takes in a year and returns a bit flag indicating whether the passed in year is a leap year or not. That’s all there is to it!

## How to determine if February is a leap year?

The function takes in the year, appends ‘0228’ to it (for February 28th) and adds a day. If the month of the next day is a 2 (as extracted by the DATEPART function), then we’re still in February so it must be a leap year! If not, it is not a leap year. select dbo.fn_IsLeapYear (1900) as ‘IsLeapYear?’

## Is the year 1900 a leap year in SQL Server?

For instance, the year 1900 was not a leap year. However, you needn’t bother yourself about leap year rules… you can let the SQL Server engine do the work for you! The following scalar function takes in a year and returns a bit flag indicating whether the passed in year is a leap year or not.

## Can a leap year be divisible by 4?

For instance, contrary to popular belief not all years divisible by 4 are leap years. For instance, the year 1900 was not a leap year. However, you needn’t bother yourself about leap year rules… you can let the SQL Server engine do the work for you!
