title: Merge to update all target table columns
body: <p>I have the same table in 2 Databases</p>
  
  <pre><code>-----------------------------------
  |           table                 |
  -----------------------------------
  | ID | col1 | col2 | ... | col(n) |
  </code></pre>
  
  <p>I need merge statement to update rows with matched IDs like this statement:</p>
  
  <pre><code>MERGE [DB1]..[table]
  USING [DB2]..[table] ON [DB1]..[table].[ID] = [DB2]..[table].[ID]
  WHEN MATCHED THEN
      UPDATE SET [DB1]..[table].[*] = [DB1]..[table].[*]
  </code></pre>
  
  <p>the problem is I have more than 30 columns so its difficult to set values column by column .</p>
