Question

I have a DateTime column row and I declare a date string:

Row:

2010-08-27 13:45:55

My string:

'2010-08-27'

How can I check if that string is in that row ?

I tried the following query:

declare @year as nvarchar(4)
declare @month as nvarchar(2)
declare @day as nvarchar(2)

set @year = '2010'
set @month = '08'
set @day = '23'

 select * FROM [dbo].[customer_import] CsrImport

 where
    (YEAR(CsrImport.import_date) = @year
       AND MONTH(CsrImport.import_date) = @month
        AND DAY(CsrImport.import_date) = @day)

but I see that it returns all rows (even that are not contains that date)

Sql server : ISDATE (Transact-SQL)

----Invalid date
SELECT ISDATE('30/2/2007')
RETURNS : 0 (Zero)
----Valid date
SELECT ISDATE('12/12/20007)'
RETURNS : 1 (ONE)
----Invalid DataType
SELECT ISDATE('SQL')
RETURNS : 0 (Zero)
