What I have tried:

SQL

USE [HerdDinner]
GO
/****** Object:  StoredProcedure [dbo].[GetUSerListByTwoParameters]    Script Date: 12/12/2016 12:36:24 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[GetUSerListByTwoParameters]
@name varchar(50)=null,
@Address varchar(500)=null

AS
BEGIN

	SET NOCOUNT ON;
	
	Begin
	SELECT 

	u.id,
	u.name,
	u.Address,
	u.scholaid

	from [dbo].[Dept] u

	


	where  (ISNULL(u.name,'') like '%'+ISNULL(@name,'')+'%') and (ISNULL(u.Address,'') like '%'+ISNULL(@Address,'')+'%') 


	End
	

END

Hi
You have to think through your problem. Do you want people to search on either name or address and return all related data? Or do you want to search on name and address and they have to line up or no result will be returned. Logical operators are a good to understand when working with datasets. See Logical Operators (Transact-SQL)[^]

Here is an example that you can use for your code:

SQL

CREATE TABLE #Dept
(
	id INT IDENTITY(1,1) PRIMARY KEY,
	name VARCHAR(50) NULL,
	[Address] VARCHAR(120) NULL,
	scholaid VARCHAR(50) NULL
)

INSERT INTO #Dept
(name ,[Address], scholaid )
VALUES('Ben Smith','1 Smith Street','No'),
('Sam Coldwell','1 Sam Street','No'),
('John Max','1 Max Street','Yes'),
('Maggie Curtis','1 Curtis Street','No'),
('Susan Jason','1 Jason Street','Yes')

INSERT INTO #Dept
([Address], scholaid )
VALUES('2 Mystreet','No')

INSERT INTO #Dept
(name , scholaid )
VALUES('Chris Mason','No')

DECLARE @name VARCHAR(50) = NULL,
@Address VARCHAR(500) = NULL

--Need to know what the name is and the address and they have to line up or no result will be returned
SET @name = 'Smith'
SET @Address = 'Smith'

	SELECT u.id,
	u.name,
	u.Address,
	u.scholaid
    FROM #Dept u
	WHERE (ISNULL(u.name,'') like '%'+ISNULL(@name,'')+'%') AND (ISNULL(u.Address,'') like '%'+ISNULL(@Address,'')+'%') 

--to allow for multiple values where either one can be blank we need to use a union
--Example 1
SET @name = 'Smith'
SET @Address = 'Smith'

	SELECT u.id,
	u.name,
	u.Address,
	u.scholaid
    FROM #Dept u
	WHERE (ISNULL(u.name,'') like '%'+ISNULL(@name,'')+'%') 
	UNION
	SELECT u.id,
	u.name,
	u.Address,
	u.scholaid
    FROM #Dept u
	WHERE (ISNULL(u.Address,'') like '%'+ISNULL(@Address,'')+'%') 

--Example 2
SET @name = 'Smith'
SET @Address = 'Max'

	SELECT u.id,
	u.name,
	u.Address,
	u.scholaid
    FROM #Dept u
	WHERE (ISNULL(u.name,'') like '%'+ISNULL(@name,'')+'%') 
	UNION
	SELECT u.id,
	u.name,
	u.Address,
	u.scholaid
    FROM #Dept u
	WHERE (ISNULL(u.Address,'') like '%'+ISNULL(@Address,'')+'%') 


DROP TABLE #Dept
