问题 I have this problem if anyone can help. There is a field (date) in my table (table1) that is a date in the format 3/31/1988 (M/D/y) , and my necessity is to define how many days have passed since that date. I have tried to give this instruction SELECT DATEDIFF(CURDATE(), date) AS days FROM table1 But it gives back 'null' and I think this happens because the two date formats are different (CURDATE() is YMD..... Is it correct? can anyone help me? Thank you in advance 回答1: You can use STR_TO

问题 I have seen many questions and answers on this topic, but none addressed my particular problem. I extended the java Calendar class (standard--no third party libraries), and needed to find the difference in days between two arbitrary dates. Method: Change the time of both dates to midnight. Convert the dates to milliseconds. Find the difference between the two dates. Divide the result by the number of milliseconds in a day (24 * 60 * 60 * 1000). The result should be the difference in days. And

问题 I have a spreadsheet that I use to track my classes. I need to set it up for export into a calendar. I have all my classes listed with begin and end dates. I want to be able to insert rows below each listed class using the date difference as the number of rows and then copy the information to those rows with the respective dates. I have the following code which inserts the rows, but then gives me a '1004' error. Public Sub Format() Dim i As Long Dim d As Long LastRow = Worksheets("GCalExport"

问题 In MySQL, I have a table with several columns, one of them being a date column. I want to be able to make a query so i can get an additional column showing the number of days between the current date (the date for each row) and the date of the previous row. The order of records is by date, and I filter by other column. e.g. id other_col date days_between_dates 1 abc 2013-05-01 0 2 abc 2013-05-07 6 3 abc 2013-05-09 2 4 abc 2013-05-19 10 5 abc 2013-05-25 6 6 abc 2013-06-03 9 7 abc 2013-06-14 11

Oracle equivalent to SQL Server/Sybase DateDiff

问题 We are now using NHibernate to connect to different database base on where our software is installed. So I am porting many SQL Procedures to Oracle. SQL Server has a nice function called DateDiff which takes a date part, startdate and enddate. Date parts examples are day, week, month, year, etc. . . What is the Oracle equivalent? I have not found one do I have to create my own version of it? (update by Mark Harrison) there are several nice answers that explain Oracle date arithmetic. If you

PHP Date diff with a difference

由 寵の児 提交于 2019-12-06 12:02:21
Please bear with me as I try to explain my predicament. I need to somehow get the difference between two dates by reversing a function I have to add months and years? Problem The date add function provided with PHP >= 5.3 does not add dates in the manner I require. Example: +3 Months to 30Nov = 2Mar Solution I use the function below (code ref 2) to produce the results I need. Example: +3 Months to 30Nov = 28Feb However when using the below (code ref 1) to calculate the difference it does so based on the addition function provide with PHP >= 5.3 in that I get 2 instead of 3 months difference
