Question

Hi Guys,

I have wrote a stored procedure to help me in insert data into table but when i Execute the procedure from the Management Studio it throw an error about one of data type  which is @ExpiryDate  which is declared as dateTime as the error saying 

Msg 102, Level 15, State 1, Line 10

Incorrect syntax near '/'.

the sproc as follow:

 

ALTER PROCEDURE [dbo].[main_Escort_Insert]

-- Add the parameters for the stored procedure here

@EscortID int,

@FirstName varchar(50),

@Surname varchar(50),

@CrbCheck bit = 0,

@CrbRef bit = false,

@ExpiryDate dateTime = null,

@Training bit = false,

 @TrainingType bit = false

AS

BEGIN

-- SET NOCOUNT ON added to prevent extra result sets from

-- interfering with SELECT statements.

SET NOCOUNT ON;

DECLARE @Escort int

-- Insert statements for procedure here

Insert Into tb_Escorts (EscortID, FirstName,Surname, [CRB_Check], [CRB_Ref],ExpiryDate, Training, TrainingType)

VALUES(@EscortID,@FirstName,@Surname,@CrbCheck,@CrbRef,@ExpiryDate,@Training,@TrainingType)

Any advice  when i execute i enter the following for the ExpiryDate as follow

@ExpiryDate =31/01/2015, 

Msg 102, Level 15, State 1, Line 10

Incorrect syntax near '/'.
