在 SQL Server 查询中返回月份名称

Question

Using SQL Server 2008 , I have a query that is used to create a view and I'm trying to display a month's name instead of an integer.

In my database, the datetime is in a column called OrderDateTime . The lines in the query that return the date is:

DATENAME(yyyy, S0.OrderDateTime) AS OrderYear,
DATEPART(MONTH, S0.OrderDateTime) AS OrderMonth

This returns a column of years and a column of months as integers. I want to return the month names (Jan, Feb, etc ). I've tried:

CONVERT(varchar(3), DATEPART(MONTH, S0.OrderDateTime) AS OrderMonth

This is obviously is incorrect, as I get

Incorrect syntax near 'AS'

message. What is the proper syntax for my query?

Answer 1

This will give you the full name of the month.

select datename(month, S0.OrderDateTime)

If you only want the first three letters you can use this

select convert(char(3), S0.OrderDateTime, 0)

Answer 2

你试过DATENAME(MONTH, S0.OrderDateTime)吗？

Answer 3

Change:

CONVERT(varchar(3), DATEPART(MONTH, S0.OrderDateTime) AS OrderMonth

To:

CONVERT(varchar(3), DATENAME(MONTH, S0.OrderDateTime)) AS OrderMonth

Answer 4

尝试这个：

SELECT LEFT(DATENAME(MONTH,Getdate()),3)

Answer 5

从表名中选择SUBSTRING (convert(varchar,S0.OrderDateTime,100),1,3)

Answer 6

在 SQL Server 2012 中，可以使用FORMAT(@mydate, 'MMMM') AS MonthName

Answer 7

这将为您提供您所要求的：

select convert(varchar(3),datename(month, S0.OrderDateTime)) 

Answer 8

SELECT MONTHNAME( `col1` ) FROM `table_name` 

Answer 9

DECLARE @iMonth INT=12
SELECT CHOOSE(@iMonth,'JANUARY','FEBRUARY','MARCH','APRIL','MAY','JUNE','JULY','AUGUST','SEPTEMBER','OCTOBER','NOVEMBER','DECEMBER')

Answer 10

Without hitting db we can fetch all months name.

WITH CTE_Sample1 AS
(
    Select 0 as MonthNumber

    UNION ALL

    select MonthNumber+1 FROM CTE_Sample1
        WHERE MonthNumber+1<12
)

Select DateName( month , DateAdd( month , MonthNumber ,0 ) ) from CTE_Sample1

Answer 11

basically this ...

declare @currentdate datetime = getdate()
select left(datename(month,DATEADD(MONTH, -1, GETDATE())),3)
union all
select left(datename(month,(DATEADD(MONTH, -2, GETDATE()))),3)
union all
select left(datename(month,(DATEADD(MONTH, -3, GETDATE()))),3)

Answer 12

对我来说，由于公司限制，无法访问 DATENAME ......但这也很容易。

FORMAT(date, 'MMMM') AS month
