    <p>the following sql always returns <code>one</code> <code>SELECT FOUND_ROWS()</code></p> <p>i have followed this example from net : </p> <pre><code>public List&lt;Employee&gt; viewAllEmployees( int offset, int noOfRecords) { String query = "select SQL_CALC_FOUND_ROWS * from employee limit " + offset + ", " + noOfRecords; List&lt;Employee&gt; list = new ArrayList&lt;Employee&gt;(); Employee employee = null; try { connection = getConnection(); stmt = connection.createStatement(); ResultSet rs = stmt.executeQuery(query); while (rs.next()) { employee = new Employee(); employee.setEmployeeId(rs.getInt("emp_id")); employee.setEmployeeName(rs.getString("emp_name")); employee.setSalary(rs.getDouble("salary")); employee.setDeptName(rs.getString("dept_name")); list.add(employee); } rs.close(); rs = stmt.executeQuery("SELECT FOUND_ROWS()"); if(rs.next()) this.noOfRecords = rs.getInt(1); } catch (SQLException e) { e.printStackTrace(); } catch (ClassNotFoundException e) { e.printStackTrace(); }finally { try { if(stmt != null) stmt.close(); if(connection != null) connection.close(); } catch (SQLException e) { e.printStackTrace(); } } return list; } </code></pre> <p>and this is my code based on the above : </p> <pre><code>public List&lt;TempcardViewModel&gt; getTempcardHistory(String query) { TempcardViewModel tempcardObj = null; List&lt;TempcardViewModel&gt; tempcardList = new ArrayList&lt;TempcardViewModel&gt;(); Connection connection = getConnection(); if (connection != null) { try { PreparedStatement assingedTempcardPS = connection.prepareStatement(query); ResultSet assingedTempcardlist_rst = assingedTempcardPS.executeQuery(); while (assingedTempcardlist_rst.next()) { tempcardObj = new TempcardViewModel(); tempcardObj.setEmpid(assingedTempcardlist_rst.getInt("empid")); tempcardObj.setEmpname( assingedTempcardlist_rst.getString("empname")); tempcardObj.setTempcardnumber(assingedTempcardlist_rst.getString("tempcardnumber")); tempcardObj.setIssuedate(assingedTempcardlist_rst.getString("issuedate")); tempcardObj.setTempcardstatus(assingedTempcardlist_rst.getString("tempcardstatus")); tempcardList.add(tempcardObj); } assingedTempcardPS.close(); assingedTempcardlist_rst.close(); PreparedStatement noOfRecordsPS = connection.prepareStatement("SELECT FOUND_ROWS();"); assingedTempcardlist_rst = noOfRecordsPS.executeQuery(); if(assingedTempcardlist_rst.next()) this.noOfRecords = assingedTempcardlist_rst.getInt(1); } catch (Exception ex) { ex.printStackTrace(); } finally { try { closeConnection(connection, null, null); } catch (Exception ex) { ex.printStackTrace(); } } } return tempcardList; } </code></pre> <p>I am using this for paging which i have done in jsp/servlets.</p> <p>when i use this <code>SELECT FOUND_ROWS()</code> it returns <code>1</code></p> <p>at the same time when i use this query : <code>SELECT COUNT(empid) FROM acct_tempcardhistory;</code></p> <p>it gives desired out put but when i go for filtering than the values are not correct.</p> <p>how to solve this, Please help me.</p> <p>thanks and regards</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.
