I am writing this query for report viewer :

SELECT Cust_Id, Clients_Title, Card_Number, Key_Person, Address_Current, Phone_Number, Mobile_Number, AreaLocation
FROM Customer_New
WHERE (Clients_Title = @Clients_Title) OR
(Address_Current = @Address_Current) OR
(Phone_Number = @Phone_Number) OR
(Mobile_Number = @Mobile_Number) OR
(AreaLocation = @AreaLocation)
What I want is:

When there are no parameter that is provided to the report viewer, all of the customer record will be displayed.
If there are parameters provided, the OR condition is implemented .
Lastly, if there is contrast in any where condition, then no record will be displayed.

Can anyone tell me how I can accomplish this?

try this

SQL

if @Clients_Title != NULL OR @Address_Current != NULL OR @Phone_Number != NULL OR @Mobile_Number !+ NULL OR @AreaLocation != NULL 
Begin 
SELECT Cust_Id, Clients_Title, Card_Number, Key_Person, Address_Current, Phone_Number, Mobile_Number, AreaLocation
FROM Customer_New
WHERE (Clients_Title = @Clients_Title) OR
(Address_Current = @Address_Current) OR

SQL

SELECT Cust_Id, Clients_Title, Card_Number, Key_Person, Address_Current, Phone_Number, Mobile_Number, AreaLocation
FROM Customer_New
WHERE (Clients_Title = ISNULL(@Clients_Title,Clients_Title)) OR
(Address_Current = ISNULL(@Address_Current,Address_Current)) OR
(Phone_Number = ISNULL(@Phone_Number,Phone_Number)) OR
(Mobile_Number = ISNULL(@Mobile_Number,Mobile_Number)) OR
(AreaLocation = ISNULL(@AreaLocation,AreaLocation))

This can be executed as a query, but stored procedure is best for better performance.

SQL

SELECT
    Cust_Id, Clients_Title, Card_Number, Key_Person,
    Address_Current, Phone_Number, Mobile_Number, AreaLocation
FROM Customer_New
WHERE
    (@Clients_Title IS NULL OR Clients_Title = @Clients_Title) AND
    (@Address_Current IS NULL OR Address_Current = @Address_Current) AND
    (@Phone_Number IS NULL OR Phone_Number = @Phone_Number) AND
    (@Mobile_Number IS NULL OR Mobile_Number = @Mobile_Number) AND
    (@AreaLocation IS NULL OR AreaLocation = @AreaLocation)
