title: Error when trying to update the table in IBM DB2 using Merge
body: <p>I have a SQL statement which I am trying to execute from a console application on IBM DB2 database.</p>
  
  <pre><code>MERGE INTO Table 1 AS A 
  USING Table 2 AS B 
  ON A.IDTEXT = B.IDTEXT AND A.STATE = 1 
  WHEN MATCHED THEN 
  UPDATE SET A.STATE = 5
  </code></pre>
  
  <p>However, I am getting this error:</p>
  
  <pre><code>ERROR [42601] [IBM][SQLDS/VSE] SQL0104N  An unexpected token "MERGE" was found following "MERGE".  Expected tokens may include:  "MERGE".
  </code></pre>
  
  <p>I am not sure what is going wrong.</p>
