sql server 2005 大数据量插入性能对比

sql server 2005大数据量的插入操作

第一，写个存储过程，传入参数，存储过程里面是insert操作，

第二，用System.Data.SqlClient.SqlBulkCopy实例方法，

数据库表Passport

CREATE TABLE [dbo].[Passport](
 [Id] [int] IDENTITY(1,1) NOT NULL,
 [PassportKey] [nchar](50) NOT NULL,
 [addtime] [datetime] NOT NULL,
 CONSTRAINT [PK_Passport] PRIMARY KEY CLUSTERED
( [Id] ASC)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

存储过程 CreatePassport

Create proc [dbo].[CreatePassport]
@passport varchar(50),
@addtime datetime
as
insert into Passport (PassportKey,addtime) values (@passport,@addtime)

 

对比测试，方法一调用存储过程，循环插入数据，方法二，构造表的对象，然后调用SqlBulkCopy

少量数据

 

大量数据

 

代码

DataTable dataTable = GetTableSchema();
            string passportKey;
            for (int i = 0; i < count; i++)
            {
                passportKey = Guid.NewGuid().ToString();
                DataRow dataRow = dataTable.NewRow();
                dataRow[1] = passportKey;
                dataRow[2] = DateTime.Now; 
                dataTable.Rows.Add(dataRow);
            }
            SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(connectionString);
            sqlBulkCopy.DestinationTableName = "Passport";
            sqlBulkCopy.BatchSize = dataTable.Rows.Count;
            SqlConnection sqlConnection = new SqlConnection(connectionString);
            sqlConnection.Open();
            if (dataTable!=null && dataTable.Rows.Count!=0)
            {
                sqlBulkCopy.WriteToServer(dataTable);
            }
            sqlBulkCopy.Close();
            sqlConnection.Close();
