不過在網上找了一些，發現都有一個特點——就是不能傳出總記錄數，干脆自己研究吧。終于，算是搞出來了，效率可能不是很好，但是我也覺得不錯了。貼代碼吧直接：也算是對自己學習mysql的一個記錄。
代碼如下:
CREATE PROCEDURE p_pageList
(
m_pageNo int ,
m_perPageCnt int ,
m_column varchar(1000) ,
m_table varchar(1000) ,
m_condition varchar(1000),
m_orderBy varchar(200) ,
out m_totalPageCnt int
)
BEGIN
SET @pageCnt = 1; -- 總記錄數
SET @limitStart = (m_pageNo - 1)*m_perPageCnt;
SET @limitEnd = m_perPageCnt;
SET @sqlCnt = CONCAT('select count(1) into @pageCnt from ',m_table); -- 這條語句很關鍵，用來得到總數值
SET @sql = CONCAT('select ',m_column,' from ',m_table);
IF m_condition IS NOT NULL AND m_condition <> '' THEN
SET @sql = CONCAT(@sql,' where ',m_condition);
SET @sqlCnt = CONCAT(@sqlCnt,' where ',m_condition);
END IF;
IF m_orderBy IS NOT NULL AND m_orderBy <> '' THEN
SET @sql = CONCAT(@sql,' order by ',m_orderBy);
END IF;
SET @sql = CONCAT(@sql, ' limit ', @limitStart, ',', @limitEnd);
PREPARE s_cnt from @sqlCnt;
EXECUTE s_cnt;
DEALLOCATE PREPARE s_cnt;
SET m_totalPageCnt = @pageCnt;
PREPARE record from @sql;
EXECUTE record;
DEALLOCATE PREPARE record;
END
asp.net
代碼如下:
/// <summary>
/// 分頁顯示
/// </summary>
/// <param name="conn">連接數據庫字符串</param>
/// <param name="perPage">每頁顯示條數</param>
/// <param name="columnList">查詢的字段字符</param>
/// <param name="tableName">查詢的表名</param>
/// <param name="condition">where條件(不用寫where)</param>
/// <param name="orderStr">排序條件(不用寫order by)</param>
/// <param name="pageInfo">返回頁碼的數組，0，1，2，3分別為 總記錄集數，總頁數，上一頁，下一頁，4開始為頁碼</param>
/// <returns>此頁的數據記錄集</returns>
public static DataTable PageList(string conn, int perPage, string url, string columnList, string tableName, string condition, string orderStr, out string[] pageInfo)
{
int pageNo = 1; //當前頁碼
int totalCnt = 1; //記錄集總數
int pageCnt = 0; //總頁數
DataTable dt = new DataTable(); //用于返回的DataTable
using (MySqlConnection myConn = new MySqlConnection(conn))
{
MySqlDataAdapter adp = new MySqlDataAdapter();
MySqlCommand cmd = new MySqlCommand();
if (!string.IsNullOrEmpty(System.Web.HttpContext.Current.Request["pageNo"]))
{
try
{
pageNo = int.Parse(System.Web.HttpContext.Current.Request["pageNo"].ToString());
}
finally
{
}
}//得到當前頁面值
cmd.Connection = myConn;
myConn.Open();
cmd.CommandText = "p_pageList";
cmd.CommandType = CommandType.StoredProcedure;
