分頁查詢SQL&&Page對象

Mysql 分頁查詢： select * from 表明 where 1=1 limit 0,10
limit 0，10
0 代表數據庫裏 記錄 起始行的下標 =（當前頁頁碼-1）*每頁顯示的數據量
10代表每頁 多少條
SQL Server 語法 ：select top 3 * from NEWS where ID not in
(select top 0 ID from NEWS)
內層 select top 0 ID from NEWS 0 代表數據庫裏 記錄 起始行的下標 =（當前頁頁碼-1）*每頁顯示的數據量
外層 select top 3 代表每次 返回多少條

//page 類用來做分頁
public class Page {
    //current page 當前頁碼
    private int currPage;
    //pagesize 每頁數量
    private int pageSize; 
    //total count 總條數
    private int totalCount;
    //totalpage 總頁數
    private int totalPageCount;
    public int getCurrPage() {
        return currPage;
    }

        this.currPage = currPage;

    }
    public void setTotalCount(int totalCount) {
    //設置記錄總條數時，順便計算一下總頁數
        this.totalCount = totalCount;
        if(totalCount%pageSize==0){
            this.totalPageCount = totalCount/pageSize;
