(Customer_first_name +'' ''+Customer_middle_name +'' ''+Customer_last_name)as CustomerName

If Customer_middle_name is null
eg:
Customer_first_name=raj
Customer_middle_name=null
Customer_last_name=kumar

The output comes
raj (2 space)kumar
but i want raj (1 space)kumar

so that Customer_middle_name is null to avoid space

You can use COALESCE to select first non-null value. So in this case something like

SQL

COALESCE(Customer_first_name + ' ', '') 
+ COALESCE(Customer_middle_name + ' ', '') 
+ Customer_last_name AS CustomerName
