Implicit conversion from data type nvarchar to varbinary is

Question

CREATE TABLE [dbo].[RegisterTable] (
    [Id]             INT           IDENTITY (1, 1) NOT NULL,
    [Name]           NVARCHAR (50) NULL,
    [email]          NVARCHAR (50) NULL,
    [HashPassword]   BINARY (32)   NULL,
    [ActivationCode] INT           NULL,
    [verify]         INT           NULL,
    [Date]           DATE          NULL,
    [Time]           TIME (7)      NULL,
    PRIMARY KEY CLUSTERED ([Id] ASC)
);

insert into RegisterTable (Name,email,HashPassword,ActivationCode,verify)
values ('mn','[email protected]',(select HASHBYTES('SHA2_256','12345')),124,0)

 

CREATE PROCEDURE [dbo].[LoginProcedure]
    @Email nvarchar(50),
    @HashPass varbinary(32)
AS
    SELECT name from RegisterTable
    where email=@Email or HashPassword =CONVERT(varbinary(MAX), HASHBYTES('SHA2_256', @HashPass))

RETURN 0

 

 

USE [C:\USERS\RAAAZZ\DOCUMENTS\VISUAL STUDIO 2013\WEBSITES\WEBSITE1\APP_DATA\DATABASE.MDF]

DECLARE    @return_value Int

EXEC    @return_value = [dbo].[LoginProcedure]
        @Email = N'[email protected]',
        @HashPass = N'12345'

SELECT    @return_value as 'Return Value'

 

 

when i exec login procedure i got error

Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
