copied!<p>Some time back, I was in same problem to deal with. After some pondering over this design we decided to do it like below.</p> <pre><code>public static Properties execute(String string, String[] columnames) throws Exception { Properties resulProperties = er.executeQuery(string, columnames); return resulProperties; } </code></pre> <p>For some specific reason, I created a field in my class as given below</p> <pre><code>private static ExecuteRequest er = new ExecuteRequest(); </code></pre> <p>In <code>ExecuteRequest</code> class below code is used.</p> <pre><code>public Properties executeQuery(String sqlstatement, String[] columnNames) throws Exception { Properties prop = new Properties(); try { prop = creteProperty(sqlstatement, columnNames); } catch (Exception e) { mlogger.report("Error executing sql statement"); throw (e); } return prop; } public Properties creteProperty(String sqlstatement, String[] columnNames) throws Exception { Properties prop = new Properties(); try { PreparedStatement stmt = ConnectionManager.getInstance().prepareStatement(sqlstatement); ResultSet rs = stmt.executeQuery(); if (rs.next()) { for (int i = 0; i < columnNames.length; i++) { String key = columnNames[i]; if (rs.getObject(key) != null) { String value = (rs.getObject(key).toString()); prop.setProperty(key, value); } else { String value = ""; prop.setProperty(key, value); } } } rs.close(); } catch (Exception e) { mlogger.report("Error executing sql statement"); throw (e); } return prop; } </code></pre> <p>You can use this approach as a solution.</p>
