按这个来算,我们那个发水票的时间就会由 10分钟-->20秒,这可太神奇了。 于是乎,下demo,测试,改成自己一般使用的方法测试,NND,还真可以说是极速。 在此贴上我的Demo:SqlBulkCopy.rar 复制代码 代码如下: using System; using System.Diagnostics; using System.Data; using System.Data.SqlClient; using Microsoft.ApplicationBlocks.Data; namespace ConsoleAppInsertTest { class Program { static int count = 1000000; //插入的条数 static void Main(string[] args) { long sqlBulkCopyInsertRunTime = SqlBulkCopyInsert(); Console.WriteLine(string.Format("使用SqlBulkCopy插入{1}条数据所用的时间是{0}毫秒", sqlBulkCopyInsertRunTime, count)); long commonInsertRunTime = CommonInsert(); Console.WriteLine(string.Format("普通方式插入{1}条数据所用的时间是{0}毫秒", commonInsertRunTime, count)); Console.ReadKey(); } /// <summary> /// 使用普通插入数据 /// </summary> /// <returns></returns> private static long CommonInsert() { Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); for (int i = 0; i < count; i++) { SqlHelper.ExecuteNonQuery(SqlHelper.SqlConnection, CommandType.Text, "insert into passport(PassportKey) values('" + Guid.NewGuid() + "')"); } stopwatch.Stop(); return stopwatch.ElapsedMilliseconds; } /// <summary> /// 使用SqlBulkCopy方式插入数据 /// </summary> /// <returns></returns> private static long SqlBulkCopyInsert() { Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); DataTable dataTable = GetTableSchema(); for (int i = 0; i < count; i++) { DataRow dataRow = dataTable.NewRow(); dataRow[2] = Guid.NewGuid(); dataTable.Rows.Add(dataRow); } //Console.WriteLine(stopwatch.ElapsedMilliseconds);//初始化数据时间 SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(SqlHelper.SqlConnection); sqlBulkCopy.DestinationTableName = "Passport"; if (dataTable != null && dataTable.Rows.Count != 0) { sqlBulkCopy.WriteToServer(dataTable); } sqlBulkCopy.Close(); stopwatch.Stop(); return stopwatch.ElapsedMilliseconds; } private static DataTable GetTableSchema() { return SqlHelper.ExecuteDataset(SqlHelper.SqlConnection, CommandType.Text, "select * from Passport where 1=2").Tables[0]; } } } 转自cnblogs的文章 SQL批量插入数据几种方案的性能详细对比 |
