SQLServer极速批量插入数据的方式

public bool Inserts(ObservableCollection<CustomerModel> models)



{



DataTable dataTable = SQLHelper.ExecteAdapter("select top 0 * from Customer", CommandType.Text, null);

foreach (var m in models)

{

DataRow dataRow = dataTable.NewRow();

dataRow[1] = m.Name;

dataRow[2] = m.Add;

dataRow[3] = m.Email;

dataRow[4] = m.Phone;

dataTable.Rows.Add(dataRow);

}

SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(SQLHelper.ConnString);

sqlBulkCopy.DestinationTableName = "Customer";

try

{

if (dataTable != null && dataTable.Rows.Count > 0)

{

sqlBulkCopy.WriteToServer(dataTable); 

}

return true;

}

catch (Exception ex)

{

return false;

}

finally

{

sqlBulkCopy.Close();

}

}

  

public static DataTable ExecteAdapter(string sql, CommandType type, params SqlParameter[] param)

        {

            using (SqlDataAdapter adapter = new SqlDataAdapter(sql, ConnString))

            {

                SqlCommand cmd = adapter.SelectCommand;

                if (param != null)

                {

                    cmd.Parameters.AddRange(param);

                }

                cmd.CommandType = type;

                DataTable dt = new DataTable();

                adapter.Fill(dt);

                return dt;

            }

        }

注明：插入5000条数据时，使用SQLHelper方式需要约35秒，使用Entity Framework方式需要约55秒，采用SqlBulkCopy方式需要约2秒，真是光速啊，爽。
