title: INSERT INTO table SELECT not working with constant values in H2 DB
body: <p>Following is the H2DB query</p>
  
  <pre><code> INSERT INTO userpermission (userid, permissionid, createddt, createdby, updateddt, updatedby)
              SELECT u.userid, p.permissionid, now(), ("1"), now(), ("1") FROM user u, permission p
              WHERE u.email = "csr_admin@example.com";
  </code></pre>
  
  <p>What I am trying to achieve is to insert a record into userpermission for user with given email address in user table, for each permission in permission table. </p>
  
  <p>Following is the error</p>
