    <p>I have code where I populate Resultset with CallableStatement.executeQuery(). I have mocked ResultSet and CallableStatement but in order to test the method i have to populate ResultSet. </p> <p>Here is the code from the method I am testing </p> <pre><code>ResultSet rset = cs.executeQuery(); while (rset.next()) { IndexVolatilityImpl tsImpl = new IndexVolatilityImpl(); tsImpl.setTradeDate(rset.getString("trade_date")); tsImpl.setTradeTime(rset.getString("trade_time")); tsImpl.setExprDate(rset.getString("expr_date")); tsImpl.setSymbol(rset.getString("symbol")); tsImpl.setTradePrice(rset.getDouble("trade_price")); tsImpl.setContractMonth(rset.getString("contract_month")); tsImpl.setMilliSecs(rset.getString("trade_time_thou")); colIndexVolatilityImpl.add(tsImpl); </code></pre> <p>I have mocked the CallableStatement and ResultSet now since they are mocked my rset comes up empty. I would like to populate Resultset and doing it as below</p> <pre><code>resultSetMock = Mockito.mock(ResultSet.class); Mockito.when(resultSetMock.getString("trade_date")).thenReturn("03/10/2011"); Mockito.when(resultSetMock.getString("trade_time")).thenReturn("12:24:56"); Mockito.when(resultSetMock.getString("expr_date")).thenReturn("03/19/2011"); Mockito.when(resultSetMock.getString("symbol")).thenReturn("VIX1"); Mockito.when(resultSetMock.getDouble("trade_price")).thenReturn(Double.valueOf("20.96")); Mockito.when(resultSetMock.getString("contract_month")).thenReturn("1"); Mockito.when(resultSetMock.getString("trade_time_thou")).thenReturn("165"); Mockito.doReturn(resultSetMock).when(callableStatementMock).executeQuery(); </code></pre> <p>But resultset checks out to be <code>null</code>.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
