问题 Is it possible to convert an integer/column to month name in MySQL? For example, 1 becomes 'Jan' or 'January'. 13 and onwards give an error, or will be never used. 回答1: We can convert the given input number to MySQL date format (focusing on month only), using Str_To_Date() function.

问题 Here's what I use to get a HH:MM string: CONVERT(varchar(5), time_requested, 108) I'm thinking there may be a more elegant way, even maybe more efficient (see similar question on How to remove the time portion of a datetime value (SQL Server)?). Requirements: the final result has to be easily convertible to a string (in order to be able to concatenate some field time_created with a field such as date_created ). the following 2 cases must be covered: HH:MM and HH:MM:SS . 回答1: Declare @D

问题 Right now, my code has the following conversion for a date field: convert(varchar, Citation.PublishedOn, 101) However, that returns dates like 03/01/2010. The request was to have the dates display as 3/1/2010 (without the leading zeros, but with a 4 digit year). I've looked at http://msdn.microsoft.com/en-us/library/ms187928.aspx and I'm not seeing anything that explicitly excludes leading zeros. How do I format the date to exclude leading zeros? 回答1: This is how I would do it: DECLARE @dt

问题 How do I use sql to get the whole month name in sql server? I did't find a way using DATEPART(mm, mydate) or CONVERT(VARCHAR(12), CreatedFor, 107) .

问题 On a EN-US regional system, what does B or b represent in a format mask? While it does nothing in VBA's Format function, both the TEXT function and Custom Number Formatting recognize b as a legal Number Format Code and return a number that I cannot determine the origin of. To further confuse matters, larger numbers return different values when formatted with bbbb and while blocks of sequential numbers return the same value, there are transitions when they jump ahead a digit. I do know that
