這個SQL存儲過程語句非常的好，但是不足的地方就是如果你的條件語句中含有'(單引號)那就很郁悶了，十分的麻煩。你可以試下改動上面的相關代碼如下：

復制代碼代碼如下:

replace(@strWhere,'''','''''')

不放心自己測試下吧。

復制代碼代碼如下:

USE [data_Test] 
GO 

DECLARE @return_value int, 
@rowCount int 

EXEC @return_value = [dbo].[pagination] 
@tblName = 'userinfo', 
@strGetFields = N'id', 
@fldName = N'id', 
@PageSize = 10, 
@PageIndex = 300, 
@OrderType = 0, 
@strWhere = null, 
@rowCount = @rowCount OUTPUT 

SELECT @rowCount as N'@rowCount' 

SELECT 'Return Value' = @return_value 

GO

最主要的DAL層代碼：

復制代碼代碼如下:

public DataSet GetList(int PageIndex, string strWhere,ref int rowCount) 
{ 
SqlParameter[] parameter = sosuo8.DBUtility.DbHelperSQL.pagePara(); 

parameter[0].Value = "userinfo"; 
parameter[1].Value = "id,userName,userWebName,createDate"; 
parameter[2].Value = "id"; 
parameter[3].Value = 10; 
parameter[4].Value = PageIndex; 
parameter[5].Value = 0; 
parameter[6].Value = strWhere; 
parameter[7].Direction = ParameterDirection.Output;//聲明為輸出類型 

DataSet ds = sosuo8.DBUtility.DbHelperSQL.RunProcedure("pagination",parameter,"userinfo"); 
rowCount = Convert.ToInt32(parameter[7].Value); 
return ds; 

} 

default.aspx.cs代碼

復制代碼代碼如下:

public partial class _Default : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!Page.IsPostBack) 
{ 
bind(); 
} 
} 


private void bind()//綁定數(shù)據(jù) 
{ 
this.anPager.PageSize = 10;//每頁記錄數(shù) 
this.anPager.AlwaysShow = true;//是否一直顯示分頁 
int rowCount = 0;//初始化記錄數(shù)為0 
string wherestr = string.Empty;//搜索關鍵字，這部分后面我在講講優(yōu)化 
sosuo8.BLL.bll_test bll = new sosuo8.BLL.bll_test(); 
this.rpt.DataSource = bll.GetList(this.anPager.CurrentPageIndex,wherestr,ref rowCount);//rowCount在經(jīng)過這個函數(shù)后，返回的是重新賦值的記錄總數(shù) 
this.anPager.RecordCount = rowCount; 
this.rpt.DataBind(); 
} 

protected void anPager_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e) 
{ 
this.anPager.CurrentPageIndex = e.NewPageIndex; 
bind(); 
} 

}
