title: Naming for contraints when creating a table
body: <p>I see following SQL in a system:</p>
  
  <pre><code>create table Account
  (
      [AccountId] int not null,
      [EquityStatus] int not null constraint DF_Account_EquityStatus default(1),
      [DerivativeStatus] int not null constraint DF_Account_DerivativeStatus default(1),
      [HasSecurityAgreement] tinyint not null constraint DF_Account_HasSecurityAgreement default(0),
      ...
  )
  </code></pre>
  
  <p>Why it names every contraints for almost every column? Is there any benefit to do this?</p>
