body: <p>How can I do for inserting a Default Value into a column of a table in Access?
  I use this instruction:</p>
  
  <pre><code>ALTER TABLE Tabella ADD Campo Double DEFAULT 0
  ALTER TABLE Tabella ADD Campo Double DEFAULT (0)
  ALTER TABLE Tabella ADD Campo DEFAULT 0
  ALTER TABLE Tabella ADD Campo DEFAULT (0)
  ALTER TABLE Tabella ADD Campo SET DEFAULT 0
  ALTER TABLE Tabella ADD Campo SET DEFAULT (0)
  </code></pre>
  
  <p>but all of these cause error. How can I do for doing it?</p>
