Question

I have a table Customer with 2 columns Name and Surname (sql Server 2008). User wants to search by Name-Surname – or just typing Jo Bloggs. Suppose a row is filled with

CustomerId        Name    Surname
1                 Jo      Bloggs

doing

select * from customer where Name like '%Jo%'             will find the records
select * from customer where Surname like '%Bloggs%'      will find the records

But How can I make it return records for if user types both Name and Surname eg Jo Bloggs?

Answer 1

This should work whether user enters First Name, Surname or both.

SELECT *
FROM customer cus
WHERE ((cus.Name like @FirstName) OR (@FirstName IS NULL)) AND
      ((cus.Surname like @Surname) OR (@Surname IS NULL))

I used two variables because entering input values into an SQL string is strongly discouraged, as it exposes to SQL Injection (other than being slower).
