title: Do not allow 0 when creating column
body: <p>I am creating a table in SQL Server and I have a column of <code>decimal</code> type that should not receive the value 0, how could I do that?</p>
  <pre><code>CREATE TABLE Producto
  (
      Idproducto [int] PRIMARY KEY NOT NULL 
          DEFAULT (NEXT VALUE FOR Idprod),
      Nombre [varchar](100) NOT NULL,
      Precio_Unitario DECIMAL (18,2) 
  );
  </code></pre>
