今天早上reader 上收到cnblogs的訂閱里看到一個關(guān)于SQL語句快速插入的文章，提到SqlBulkCopy，感覺不錯，按他的測試SqlBulkCopy要比普通插入快近30倍，
按這個來算，我們那個發(fā)水票的時間就會由 10分鐘–>20秒，這可太神奇了。
于是乎，下demo，測試，改成自己一般使用的方法測試，NND，還真可以說是極速。
在此貼上我的Demo:
代碼如下:
using System;
using System.Diagnostics;
using System.Data;
using System.Data.SqlClient;
using microsoft.ApplicationBlocks.Data;
namespace ConsoleAppInsertTest
{
class Program
{
static int count = 1000000; //插入的條數(shù)
static void Main(string[] args)
{
long sqlBulkCopyInsertRunTime = SqlBulkCopyInsert();
Console.WriteLine(string.Format(“使用SqlBulkCopy插入{1}條數(shù)據(jù)所用的時間是{0}毫秒”, sqlBulkCopyInsertRunTime, count));
long commonInsertRunTime = CommonInsert();
Console.WriteLine(string.Format(“普通方式插入{1}條數(shù)據(jù)所用的時間是{0}毫秒”, commonInsertRunTime, count));
Console.ReadKey();
}
///
///
///
private static long CommonInsert()
{
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
for (int i = 0; i {
SqlHelper.ExecuteNonQuery(SqlHelper.SqlConnection, CommandType.Text, “insert into passport(PassportKey) values(‘” + Guid.NewGuid() + “‘)”);
}
stopwatch.Stop();
return stopwatch.ElapsedMilliseconds;
}
///
///
///
private static long SqlBulkCopyInsert()
{
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
DataTable dataTable = GetTableSchema();
for (int i = 0; i {
DataRow dataRow = dataTable.NewRow();
dataRow[2] = Guid.NewGuid();
dataTable.Rows.Add(dataRow);
}
//Console.WriteLine(stopwatch.ElapsedMilliseconds);//初始化數(shù)據(jù)時間
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];
}
}
}
