4.真分页操作Dal BaseDalNew.cs
/// <summary> /// 分页查询 /// </summary> /// <param name="tableName"></param> /// <param name="getFields"></param> /// <param name="orderName"></param> /// <param name="desc"></param> /// <param name="pageSize"></param> /// <param name="pageIndex"></param> /// <param name="strWhere"></param> /// <param name="count"></param> /// <returns></returns> public virtual DataTable DataPage(string tableName, string getFields, string orderName, string desc, int pageSize, int pageIndex, string strWhere, out int count) { int pageStart, pageEnd = 0; pageEnd = pageSize * pageIndex; pageStart = pageEnd - pageSize + 1; string sql = "select " + getFields + " from ( select ROW_NUMBER() over(order by " + orderName + " " + desc + ") as row,* from " + tableName + " where " + strWhere + ") r where r.row between " + pageStart + " and " + pageEnd; string sql1 = "select " + getFields + " from ( select ROW_NUMBER() over(order by id) as row,* from " + tableName + " where " + strWhere + ") r order by r." + orderName + " " + desc; DataTable dt = SqlHelper.Search(sql); DataTable dt2 = SqlHelper.Search(sql1); count = dt2.Rows.Count; return dt; }
5.ADO 操作数据库类 sqlhelper.cs
using System; using System.Collections.Generic; using System.Data; using System.Data.SqlClient; using System.Linq; using System.Text; using System.Threading.Tasks; namespace DQPA.DAL { public class SqlHelper { static string constr = System.Configuration.ConfigurationSettings.AppSettings["sqlcon"]; /// <summary> /// 数据库连接字符串 /// Data Source=数据库地址;Initial Catalog=数据库名称;Persist Security Info=True;User ID=用户名;Password=密码 /// </summary> //static string constr = "Data Source=.;Initial Catalog=;Persist Security Info=True;User ID=sa;Password="; //执行增删改操作 返回受影响行数 public static int ExcuteSql(string sql) { int result = 0; using (SqlConnection con = new SqlConnection(constr)) { SqlCommand cmd = new SqlCommand(sql, con); con.Open(); result = cmd.ExecuteNonQuery(); } return result; } //执行查询操作 返回datatable 查询所有 public static DataTable Search(string field, string tableName) { DataTable dt = null; using (SqlConnection con = new SqlConnection(constr)) { string sql = "select" + field + "from " + tableName; SqlDataAdapter adp = new SqlDataAdapter(sql, con); con.Open(); DataSet ds = new DataSet(); if (ds != null) { adp.Fill(ds); dt = ds.Tables[0]; } } return dt; } //执行查询操作 返回datatable 条件查询 public static DataTable Search(string field, string tableName, string where) { DataTable dt = null; using (SqlConnection con = new SqlConnection(constr)) { string sql = "select " + field + " from " + tableName + " where 1=1" + where + ""; SqlDataAdapter adp = new SqlDataAdapter(sql, con); con.Open(); DataSet ds = new DataSet(); if (ds != null) { adp.Fill(ds); dt = ds.Tables[0]; } } return dt; } //执行查询操作 返回datatable sql语句查询 public static DataTable Search(string sql) { using (SqlConnection con = new SqlConnection(constr)) { con.Open(); SqlDataAdapter adp = new SqlDataAdapter(sql, con); DataSet ds = new DataSet(); DataTable dt = null; if (ds != null) { adp.Fill(ds); dt = ds.Tables[0]; } return dt; } } //执行存储过程操作 返回datatable 分页查询 public static DataTable ExcuteProc(string procName, SqlParameter[] parameters) { //DataTable dt = null; using (SqlConnection con = new SqlConnection(constr)) { //声明执行sql语句对象 SqlCommand cmd = new SqlCommand(procName, con); //制定SqlCommand执行的是存储过程 cmd.CommandType = CommandType.StoredProcedure; foreach (var item in parameters) { cmd.Parameters.Add(item); } SqlDataAdapter adp = new SqlDataAdapter(cmd); con.Open(); DataSet ds = new DataSet(); DataTable dt = null; if (ds != null) { adp.Fill(ds); dt = ds.Tables[0]; } return dt; } } //执行事务操作 public static int ExcuteTran(List<string> sqls) { using (SqlConnection con = new SqlConnection(constr)) { con.Open(); SqlTransaction tran = con.BeginTransaction();//开始一个事物 int result = 0; try { foreach (string sql in sqls) { SqlCommand cmd = new SqlCommand(sql, con); cmd.Transaction = tran; result = cmd.ExecuteNonQuery(); } tran.Commit(); } catch (Exception) { tran.Rollback(); } return result; } } /// <summary> /// 分页查询 /// </summary> /// <param name="tableName"></param> /// <param name="getFields"></param> /// <param name="orderName"></param> /// <param name="desc"></param> /// <param name="pageSize"></param> /// <param name="pageIndex"></param> /// <param name="strWhere"></param> /// <param name="count"></param> /// <returns></returns> public static DataTable DataPage(string tableName, string getFields, string orderName, string desc, int pageSize, int pageIndex, string strWhere, out int count) { int pageStart, pageEnd = 0; pageEnd = pageSize * pageIndex; pageStart = pageEnd - pageSize + 1; string sql = "select " + getFields + " from ( select ROW_NUMBER() over(order by " + orderName + " " + desc + ") as row,* from " + tableName + " where " + strWhere + ") r where r.row between " + pageStart + " and " + pageEnd; string sql1 = "select " + getFields + " from ( select ROW_NUMBER() over(order by id) as row,* from " + tableName + " where " + strWhere + ") r order by r." + orderName + " " + desc; DataTable dt = Search(sql); DataTable dt2 = Search(sql); count = dt2.Rows.Count; return dt; } } }
