Hello Everyone,

I am trying to select specific record from sql server based on user date selection, date format for users is in this format:dd/mm/yyyy from Ajax calenda extender, and i use getdate() to store date in the table, i.e. date format in the table is in this format:2015-03-16 08:36:08.330.

I have tried this:

SQL

ALTER PROCEDURE [dbo].[SelectRCOByDate] 
	-- Add the parameters for the stored procedure here
	@Username Varchar (50)=NULL,
	@AttndDate DateTime = NULL
AS
IF @AttndDate is null
SET @AttndDate = CONVERT(VARCHAR, getdate(), 103)
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;

    -- Insert statements for procedure here
	SELECT r.Username AS Username, r.surname AS Surname, r.firstname AS Firstname,u.branch AS Branch, r.RTime AS ResumptionTime,r.CTime AS ClosureTime, CONVERT(VARCHAR, r.ATTNDDate, 103) AS ATTNDATE
	FROM RCORegister r
	INNER JOIN UserMgmt u ON r.Username = u.Username
	WHERE  CONVERT(VARCHAR, r.ATTNDDate,103)  = @AttndDate 
	ORDER BY  r.ATTNDDate DESC

END

but i am having this error:
Error converting data type varchar to datetime.

Please is there anything i have done wrong? Thanks in advance.

Replace:

SQL

SET @AttndDate = CONVERT(VARCHAR, getdate(), 103)

with:

SQL

SET @AttnDate = DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

to reject/remove time part then change WHERE condition to:

SQL

WHERE AttndDate BETWEEN @AttndDate AND DATEADD(ss, -1, DATEADD(dd, 1, @AttndDate))

DateAdd (SQL)[^]

[EDIT]

SQL

ALTER PROCEDURE [dbo].[SelectRCOByDate] 
	-- Add the parameters for the stored procedure here
	@Username Varchar (50)=NULL,
	@AttndDate DateTime = NULL
AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;
        
        SET DATETIMEFORMAT dmy;

       IF @AttndDate is null SET @AttndDate = GETDATE()

       SET @AttndDate = DATEADD(dd, DATEDIFF(dd, 0, @AttndDate), @AttndDate)
       DECLARE @AttEndDate DATETIME = DATEADD(dd, -1, DATEADD(ss, -1, @AttndDate))
 
    -- Insert statements for procedure here
	SELECT r.Username AS Username, r.surname AS Surname, r.firstname AS Firstname,u.branch AS Branch, r.RTime AS ResumptionTime,r.CTime AS ClosureTime, CONVERT(VARCHAR, r.ATTNDDate, 103) AS ATTNDATE
	FROM RCORegister r
	INNER JOIN UserMgmt u ON r.Username = u.Username
	WHERE  r.ATTNDDate >= @AttndDate AND r.ATTNDDate <= @AttEndDate
	ORDER BY  r.ATTNDDate DESC
        --OR WHERE  r.ATTNDDate BETWEEN @AttndDate AND @AttEndDate
 
END
