Question

I have to create a View that shows a field created by concatenating some other fields. The simple query that I use is this one:

SELECT     
    CODPROY, DESCPROY, USER, CODPROY + ' - ' + USER + ' - ' + DESCPROY AS Expr
FROM    
    dbo.PROY

The problem is that USER may be NULL and in this case I have to insert a default text, something like ‘NOT AVAILABLE’. Can this be done in a view?

Answer 1

Use coalesce if you are using SQL Server

SELECT 
  CODPROY, 
  DESCPROY, 
  USER, 
  CODPROY + ' - ' + COALESCE(USER,'NOT AVAILABLE') + ' - ' + DESCPROY AS Expr 
FROM dbo.PROY
