问题 I'm trying to write a script which is supposed to send out an email and create two calender entries when submitting a form. To be honest, this is my first script and I am very happy that the email is send out and the calender entries are working as well. The thing which gives me a headache is to subtract 5 days (actually x days) from a defined date. First I thought I could simply do something like var liveday = e.values[2]; var newday = liveday-5; well, this didn't work :-) I tried more: var

问题 I am quite a beginner when it comes to Oracle. I am having trouble figuring out how to do something similar to this : SELECT ID, NAME, TO_CHAR(DATEBIRTH, 'DD/MM/YYYY HH24:MI:SS') FROM PEOPLE WHERE DATEBIRTH >= ANOTHERDATE - NDAY To put it short, I want to select everyone who were born N days before a specific date and time but I am not quite sure that this is the way to do it nor that it would give me the results I expect. PS: I am developping under oracle8i. 回答1: Your query looks correct to

Fill in missing year in ordered list of dates

问题 I have collected some time series data from the web and the timestamp that I got looks like below. 24 Jun 21 Mar 20 Jan 10 Dec 20 Jun 20 Jan 10 Dec ... The interesting part is that the year is missing in the data, however, all the records are ordered, and you can infer the year from the record and fill in the missing data. So the data after imputing should be like this: 24 Jun 2014 21 Mar 2014 20 Jan 2014 10 Dec 2013 20 Jun 2013 20 Jan 2013 10 Dec 2012 ... Before lifting my sleeves and start

Difference in time between records

由 百般思念 提交于 2019-12-07 04:48:13
问题 I have a table that has (among others) a timestamp column (named timestamp; it's a standard Oracle DATE datatype). The records are about 4-11 minutes apart, about 7 or 8 records every hour, and I'm trying to determine if there is any pattern to them. Is there an easy way to see each record, and the number of minutes that record occurred after the previous record? Thanks, AndyDan 回答1: This is Oracle 9i+, using the LAG function to get the previous timestamp value without needing to self join:

How to create a datetime from parts in Oracle/PLSQL?

由 安稳与你 提交于 2019-12-06 03:12:17
I have a date (4/30/2012), an hour (4) and a minute (45). I need to convert that to an Oracle datetime value for comparison in a PLSQL/Oracle SELECT statement. Ideally, there would be a function like this (C# since I know it a little better): var date = "4/30/2012"; var hour = "4"; var minute = "45"; DateTime myDateTime = convertDateTime(date, hour, minute); I have a table with three columns to make up the date and time of an event. I have another table that has items that may or may not match based on their start and end dates. In pseudo SQL, here's what I'm trying to do: SELECT G.Name,
