  </ Td> </ tr> <tr> <td height="35" valign="top" class="ArticleTeitle"> <table width="722" border="0"> <tr> <td> </ td> </ tr> </ table> 

  The current widespread use of the paging option is to cache query results in the HttpSession or state bean, the time from turning the pages out of a cache data.    Such an approach has two major drawbacks: First, users may see is measured data; Second, if the volume of data is very large for the first time spent traversing the results of assembly for a long time, and cache data will take up much of memory, efficiency has declined markedly. 
  Other common methods are also on each page-a database, only removed from a ResultSet data (using rs.last (); rs.getRow (), and was recorded of the total number, use rs.absolute () positioning Go to Start records).    In some ways this database (such as oracle) JDBC is the need to achieve almost all records traversing experimental proof in the record number of large, very slow speed. 
  As for the cache result sets ResultSet methods are is a completely wrong approach.    ResultSet because Connection closed or in the Statement will also be closed, if prolonged occupation will ResultSet effective database connection. 

  Pagination therefore relatively good practice should be the time to turn the pages, each from a database search page size of the data block.    Although each page-this need to query the database, but for a very small number of records, not data transmission network, the use of connection pool can be the most time-consuming little more than the establishment of a database linking process.    In the database and a variety of mature-optimization techniques used to enhance the speed of enquiries than in the application server cache done more effectively. 

  In oracle database query results, the Bank said that the use of pseudo-out ROWNUM (from the beginning).    For example, select * from employee where rownum <10 return to the previous record of 10.    But since rownum in enquiries after the sort of assignment before, so for employee birthday by the sort 100-120 record should write: 
  [Pre] select * from ( 
  Select my_table .*, rownum as my_rownum from ( 
  Select name, birthday from employee order by birthday 
  ) My_table where rownum <120 
  ) Where my_rownum> = 100 
  [/ Pre] 
  MySQL can use the LIMIT clause: 
  Select name, birthday from employee order by birthday LIMIT 99,20 
  DB2 has rownumber () function to access the current line number. 
  SQL Server not studied, can refer to the article: http://www.csdn.net/develop/article/18/18627.shtm 

  In the process of Web page will be frequently used, but the realization of the details page programming is trouble in the course of things.    Most of the paging display query operation at the same time to deal with complex multiple search criteria, sql statement needs dynamic mosaic composition, coupled with the need for paging record positioning, the total number of records, as well as the result of a query on Ergodic, Packaging, and that process will become very complex and difficult to understand.    Some of the tools needed to streamline category paging code, programmers focus on the business logic part.    Below are the two I design tools categories: 
  PagedStatement Packaging, a database connection, the record number of enquiries, paging enquiries, outcome data package and the closure of operations such as database connectivity, support and the use of dynamic setting parameters PreparedStatement. 
  PetStore RowSetPage reference to the page by page iterator pattern for Packaging Design RowSetPage query results (using OracleCachedRowSet from a cache for data on the use of database query results CachedRowSet Packaging, please refer to JSP pages enquiries revealed that commonly used models) as well as the current paginated, and the total number of records, the current record number, and other information, and can generate simple HTML page code. 
  PagedStatement the results of inquiries into RowsetPage package. 

  Below is the use of simple examples: 


  / / DAO data for some of the code: 
…
  Public RowSetPage getEmployee (String gender, int pageNo) throws Exception ( 
  String sql = "select emp_id, emp_code, user_name, real_name from employee where gender =?"; 
  / / Oracle Database tab for realization per page 5 
  PagedStatement pst = new PagedStatementOracleImpl (sql, pageNo, 5); 
  Pst.setString (1, gender); 
  Return pst.executeQuery (); 
  ) 


  / / Servlet handle enquiries request of the code: 

…
  Int pageNo; 
  Try ( 
  / / Pageno parameters can be obtained through the user's selection of a page 
  PageNo = Integer.parseInt (request.getParameter ( "pageno")); 
  ) Catch (Exception ex) ( 
  / / The default is the first page 
  PageNo = 1; 
  ) 
  String gender = request.getParameter ( "gender"); 
  Request.setAttribute ( "empPage" myBean.getEmployee (gender, pageNo)); 
…

  / / JSP showed some code 
  <% @ Page import = "page.RowSetPage"%> 
…
  <script Language="javascript"> 
  Function doQuery () ( 
  Form1.actionType.value = "doQuery"; 
  Form1.submit (); 
  ) 
  </ Script> 
…
  <form Name=form1 method=get> 
  <input Type=hidden name=actionType> 
  Sex: 
  <Input type = text name = gender size = 1 value ="<%= request.getParameter ( "gender ")%>"> 
  <input Type=button value="查询" onclick="doQuery()"> 
<%
  RowSetPage empPage = (RowSetPage) request.getAttribute ( "empPage"); 
  If (empPage == null) = RowSetPage.EMPTY_PAGE empPage; 
%>
…
  <table Cellspacing="0" width="90%"> 
  <tr> <td> ID </ td> <td> code </ td> <td> user name </ td> <td> name </ td> </ tr> 
<%
  Javax.sql.RowSet empRS = (javax.sql.RowSet) empPage.getRowSet (); 
  If (empRS! = Null) while (empRS.next ()) ( 
%>
<tr>
  <td> <% = EmpRS.getString ( "EMP_ID ")%></ td> 
  <td> <% = EmpRS.getString ( "EMP_CODE ")%></ td> 
  <td> <% = EmpRS.getString ( "USER_NAME ")%></ td> 
  <td> <% = EmpRS.getString ( "REAL_NAME ")%></ td> 
  </ Tr> 
<%
  ) / / End while 
%>
<tr>
<%
  / / Show the total number of pages and the current page (pageno), as well as paging code. 
  / / Here doQuery pages submitted for action on the javascript function name, logo pageno for the parameters of the current page 
%>
  <td Colspan=4> <% = empPage. GetHTML ( "doQuery", "pageno ")%></ td> 
  </ Tr> 
  </ Table> 
  </ Form> 

  Figure effect: 


  Pagination will show that because of the general conditions and with enquiries for action, the page should have a check on the conditions and methods for the javascript (as in the above doQuery), the RowSetPage.getHTML () generated paging code on the user choice new page directly in front of the callback to deal with enquiries javascript methods.    Attention to the outcome of the enquiries revealed that the last time on the need to maintain conditions, such as <input type = text name = gender size = 1 value ="<%= request.getParameter ( "gender ")%>">.    At the same time as the parameters of a page can be designated, and therefore support in the same pages in a number of paging zones. 
  Another paging code is generated for each page URL, page inquiry parameters and attached to the URL as QueryString behind.    This method is the deficiencies in the conditions for dealing with complex, difficult, and the need for action designated to deal with the servlet, and may not be suitable for certain custom query operation. 
  If the RowSetPage.getHTML () generation is not satisfied with the default code page can be dealt with the preparation of their own paging code RowSetPage provide many getter methods are used to get the relevant information (such as the current page, total pages, the total number of records and the current record number, etc.). 
  In practical application can be made and shown on page jsp taglib to further streamline the JSP code, shielding Java Code.

[QQ Lianliankan imitate ideas:

  Abstract: imitate QQ Lianliankan [ideas] 

  From: Stroll resources Station 


  Lianliankan the requirements of a directory of two arbitrary points can map a three connectivity solutions linking alerts Tip 4 5 6 props issue a map, the requirements of Lianliankan 
  1: To connect the two points on the graph are the same. 
  2: one does not exist between the two "obstacles" and pack no more than two points of the line. 
  So analysis can be seen, usually divided into three situations that [Legend] 
  Assumption of a two-dimensional array to a Lianliankan said that the map of elements in an array is 0 representatives of the game in the space of the interface, the value is greater than 0 representatives of the various games connect object (a representative of the stars, two representatives of Penguin) 

  Scenario 1: To connect the two points with a straight line 

  0 0 0 0 0 0 
  0 2 0 0 0 2 * * 
  0 0 0 0 0 0 
  Scenario 2: After a break point connected (+, the representative of Pack) 
  0 0 0 0 0 0 
  0 2 0 0 0 + + * —— 
  0 + 0 0 0 2 * + —— 
  (Two paths can be connected) 
  Case 3: After two discount points connected (for the penguins, that figure 2) 

  0 + 0 0 0 + 0 0 0 0 0 0 
  0 2 0 1 0 2 0 2 0 1 0 2 
  0 0 0 0 0 0 or 0 + 0 0 0 + 
  As an obstacle to this, so it is necessary to two packs can be connected two points, two points can arbitrarily connected Wayfinding algorithm is the core of the entire game algorithm.    Implementation of the online version of many, this method is relatively easy, I understand that one way ^ o ^, but also hope that we can put forward their valuable comments and suggestions, I would like to thank the. 
  Thinking as follows: 
  1 2:00 a straight line can be linked to good judgement (a simple cycle judgement required) 
  2 Legend of the above two cases, the coordinates of discount points are fixed, that is, break point either 
  [1 point with the coordinates x, even y coordinates of the point 2] or [even the coordinates of a point y, and even the coordinates of points 2 x] 

  Y 
|
|
  | + * —— 
  | + —— * 
  —————- X 
  Therefore, we need only point a judge even be connected to the break point, and even to the point of two discount points that can be connected with point 1 and 2 can even point connectivity.    And as a result break point and the two points are connected with a straight line, so can be easily judge concluded the first step. 
  3 situation into a situation of the three, (this step is the most impact on the algorithm performance and areas where improvement is needed) 
  How transformati
