How can I get SQL Server to use User Locale for Date format for a Query?

问题

I have created the following simple table for this test:

DROP TABLE DateFieldTest
CREATE TABLE DateFieldTest
(
    DateField Date NOT NULL
)

INSERT INTO DateFieldTest VALUES ('2013-07-15')
INSERT INTO DateFieldTest VALUES ('2013-07-16')
INSERT INTO DateFieldTest VALUES ('2013-07-17')

INSERT INTO DateFieldTest VALUES ('2013-07-05')
INSERT INTO DateFieldTest VALUES ('2013-07-06')
INSERT INTO DateFieldTest VALUES ('2013-07-07')

INSERT INTO DateFieldTest VALUES ('2013-06-05')
INSERT INTO DateFieldTest VALUES ('2013-06-06')
INSERT INTO DateFieldTest VALUES ('2013-06-07')

INSERT INTO DateFieldTest VALUES ('2013-05-05')
INSERT INTO DateFieldTest VALUES ('2013-05-06')
INSERT INTO DateFieldTest VALUES ('2013-05-07')

SELECT * from DateFieldTest where DateField >= '2013-07-05'
SELECT * from DateFieldTest where DateField >= '2013-07-06'
SELECT * from DateFieldTest where DateField >= '2013-07-07'

SELECT * from DateFieldTest where DateField >= '05/07/2013'
SELECT * from DateFieldTest where DateField >= '06/07/2013'
SELECT * from DateFieldTest where DateField >= '07/07/2013'

SELECT * from DateFieldTest where DateField >= '07/05/2013'
SELECT * from DateFieldTest where DateField >= '07/06/2013'
SELECT * from DateFieldTest where DateField >= '07/07/2013'

SELECT * from DateFieldTest where DateField >= '24/04/2013'

All the queries except the last one execute. The problem I have is that my different users have different date formats, and some users date format is dd/mm/yyyy, not the standard US/Canada of mm/dd/yyyyy.

I know I can use the convert function to cast a date, but I am working with older queries and software that is simply using the date entered by the user. I want to know how to instruct SQL Server 2005+ to use the user's Short Date format in their locale.

回答1:

You can set the date format using SET DATEFORMAT XXX

SET DATEFORMAT DMY
SELECT * from DateFieldTest where DateField >= '24/04/2013'
