由 醉酒当歌 提交于 2019-12-11 06:44:16
问题 There is a translation for Excel built-in date format [h]: mm:ss in T-SQL or any SQL platform? example: General [h]:mm:ss [mm]:ss [ss] 1.00000 24:00:00 1440:00 86400 1.00000 24:00:00 1440:00 86400 SUM 2.00000 48:00:00 2880:00 172800 For T-SQL I will select Without century (yy) (1) With century (yyyy) Standard Input/Output (3) 14 114 - hh:mi:ss:mmm(24h) Or by default 108, I am discerning is do I have to recreate a function that can do the hh:mi:ss:mmm ( +24h )? Comments are very welcome; 回答1:

MySQL query to update records with incremented date

由 心不动则不痛 提交于 2019-12-09 23:43:44

The last query I have at the bottom of the

问题 In the docs I could only find a way to create a date from a string, e.g. DATE '2000-01-02' . This is utterly confusing and annoying. What I want instead is a function that takes three parameters, so I could do make_date(2000, 1, 2) and use integers instead of strings, and returns a date (not a string). Does PostgreSQL have such a built-in function? The reason I'm asking this is because I dislike the use of strings for things that are not strings. Dates are not strings; they're dates. The

问题 I have a table in SQL Server 2012 that is updated manually every month to reflect what date is a file expected to come in. The date rule already has values but the expected date column is what is updated manually. If its expected on BD1(Business Day 1) I will update to the first non-weekend day of the month. If its expected on CD1(Calenday Day 1) I will update to the 1st regardless if it falls on a weekday or a weekend and so forth. Is it possible to write an update query where it would loop

First day of the next month

问题 I'm trying get the results where it only displays OrderDates before the LAST day of the CURRENT month. I'm guessing it would be like this... SELECT OrderDate FROM Orders WHERE OrderDate < (code for first day of the next month?) 回答1: First day of next month: sql-server 2012+ DATEADD(d, 1, EOMONTH(current_timestamp)) sql-server 2008 and older: DATEADD(m, DATEDIFF(m, -1, current_timestamp), 0) 回答2: Your question is somewhat ambiguous, but this will give you '(code for the first day of the month)
