Subject [jira] Commented: (DERBY-953) Add miscellaneous Statement methods introduced by JDBC 4
Date Wed, 22 Mar 2006 23:07:02 GMT
    [ http://issues.apache.org/jira/browse/DERBY-953?page=comments#action_12371482 ] 

Daniel John Debrunner commented on DERBY-953:
---------------------------------------------

I think this is the correct fix, a slightly modified version of the second patch, removing
the assumption that if
checkExecStatus throws an exception that the statement is closed. This them matches the ResultSet.isClosed()
approach.

     /**
+     * Tell whether this statment has been closed or not.
+     *
+     * @return <code>true</code> is closed, <code>false</code> otherwise.
+     * @exception SQLException if a database access error occurs.
+     */
+    public boolean isClosed() 
+        throws SQLException {
+        // If active, verify state by consulting parent connection.
+        if (active) {
+            try {
+                checkExecStatus();
+            } catch (SQLException sqle) {
+            }
+        }
+        return !active;
+    }
