Hi Experts,
Please help me in Nvarchar to Datetime, my scenario is as below
I'm getting data in NVARCHAR and format is "03\15\2010 01" i want this to be in DATETIME format like data "03-15-2010 01:00:00.000".
I've tried below but no luck
DECLARE @ndate nvarchar(50) = N'2010/03/15 01'
SELECT CONVERT(datetime, stuff(stuff(stuff(@ndate,3,0,'/'),6,0,'/'),8,0,'/'), 101)
Expecting result to be like 2010-03-15 01:00:00.000
Thanks in Advance

SELECT CONVERT(DATETIME,REPLACE('03\15\2010 01','\','/')+':00:00')

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

DECLARE @ndate nvarchar(50) = N'2010/03/15 01'
SET @Ndate = @ndate + ':00:00'
SELECT CONVERT(datetime, @ndate, 101)

DECLARE @ndate nvarchar(50) = N'2010/03/15 01'
SET @Ndate = @ndate + ':00:00'
SELECT CONVERT(datetime, @ndate, 101)

The OP has "\"s in the dates.

You've put:
NVARCHAR and format is "03\15\2010 01"
then you've put:
DECLARE @ndate nvarchar(50) = N'2010/03/15 01'
Which one is it?

Except for replacing backslashes with slashes, it won't actually matter. SQL Server will handle both without having to identify which format it's in IF you have the proper language settings.

SELECT CONVERT(DATETIME,REPLACE('03\15\2010 01','\','/')+':00:00')
,CONVERT(DATETIME,REPLACE('2010/03/15 01','\','/')+':00:00') --Of course, REPLACE is overkill for this one.

,CONVERT(DATETIME,REPLACE('2010/03/15 01','\','/')+':00:00') --Of course, REPLACE is overkill for this one.

So this works:
SET LANGUAGE us_english; SELECT CONVERT(DATETIME,REPLACE('03\15\2010 01','\','/')+':00:00') ,CONVERT(DATETIME,REPLACE('2010/03/15 01','\','/')+':00:00') --Of course, REPLACE is overkill for this one.
But this doesn't:
SET LANGUAGE British; SELECT CONVERT(DATETIME,REPLACE('03\15\2010 01','\','/')+':00:00') ,CONVERT(DATETIME,REPLACE('2010/03/15 01','\','/')+':00:00') --Of course, REPLACE is overkill for this one.
