![]() Expected: select cls_util. Insert into holidays values (to_date('','DD/MM/YYYY') Test cases (these are some public holidays in Western Australia): insert into holidays values (to_date('','DD/MM/YYYY') WHERE base_days - count_so_far < ABS(p_working_days) SELECT MIN(day - (ABS(p_working_days) - (base_days - count_so_far))) WHERE base_days - count_so_far < p_working_days SELECT MAX(day + p_working_days - (base_days - count_so_far)) 'add_working_days: cannot handle fractional p_working_days (' IF p_working_days != TRUNC(p_working_days) THEN IF p_date IS NULL OR p_working_days IS NULL THEN Here’s our function to take any date (at least, any date between 20) and add x business days (positive or negative): FUNCTION add_working_days (p_date IN DATE, p_working_days IN NUMBER) In our final solution, we’ll also need to UNION in the date parameter as well, for the case where there are no holidays between the starting date and the number of business days requested. You’ll find this logic in the function below. If you run this query and examine each row in order of day, if you take base_days and subtract count_so_far, when the result is less than x, then base_days – count_so_far is the number of extra days we need to add to the holiday’s date to give us the answer. Move the start date to the next Monday, then add the calculated weeks. Multiply it by seven to give the number of weeks spanned. So if the timeframe is longer than a working week (five days) you can: Find the number of weeks by taking the floor of the N / 5. SQL> select oldest - creation from mytable If your date is stored as character data, you have to convert it to a date type first. Then loop over the last few days to get the result. When you delve deeper you find that querying the table with “ DUE_DATE + 35 p_date This will give you the difference in days. “List only records where today’s date is more than 35 business days after the due date from the record.” Create a report to list records meeting some criteria, one of which is: It starts out as a fairly simple, innocent business requirement. First, you can ensure that the column youre inserting into is of type TIMESTAMP WITH TIME ZONE. ![]() Legal notices.Home PL/SQL Add business days Add business days You can insert the value returned by SYSTIMESTAMP in a few ways. © Copyright 2015, Oracle and/or its affiliates. ![]() The resulting date is returned in the same date format. Because 2008 is a leap year, the correct day of the year (counting consecutively from January 1) is 139. Subtracting three years results in the date May 18, 2006. The given date (09/138) using date format I is May 18, 2009. (Note that if you enter "44" as a string, it is automatically converted to an integer.) Uses the given date (02/01/09) and adds 44 months. Here are some examples (assume the current date is 07/01/09):ĭefaults to the current date which is specified as Date( ) and adds 10 days. To get as the result, you would use two calculations, first adding the year, then adding the day. ![]() For instance, if you tell the system to add one day and one year to the date, the result is -not. This function tells the system to add days, months, and years- in that order. The result reflects the appropriate year, month, and day. For example, you can add 300 days and 40 months to a date. You do not have to divide the values into components. If you enter a negative parameter, the system subtracts the specified days, months, or years. The Days, Months, and Years parameters can be negative or positive. The result is formatted according to the Format parameter. This function adds a specified number of days, months, and years to a given date. The default is zero (0).Įnter the number of years. The default is zero (0).Įnter the number of months. The default is date format 1 (MM/DD/YY).Įnter the number of days. The default is the current date.Įnter a date format string that describes the contents of the Date parameter. The system assumes your entry to be in the format specified in the Format parameter. SyntaxĭateAdd (Date, Format, Days, Months, Years)Įnter a date string. Use this function to add a specified number of days, months, and/or years to a date. You are here: Function Reference > Alphabetical Listing > D > DateAdd DateAdd
