数据插入使用了以下几种方式
1. 逐条数据插入
2. 拼接sql语句批量插入
3. 拼接sql语句并使用Transaction
4. 拼接sql语句并使用SqlTransaction
5. 使用DataAdapter
6. 使用TransactionScope及SqlBulkCopy
7. 使用表值参数
数据库使用SQL Server，脚本如下
create table TestTable
(
Id int
,Name nvarchar(20)
)
程序中生成测试DataTable结构和测试数据的类如下
[c-sharp] view plaincopyPRint?
1.public class Tools
2.{
3. public static DataTable MakeDataTable()
4. {
5. DataTable table = new DataTable();
6.
7. //生成DataTable的模式(schema)
8. table.Columns.Add("Id", Type.GetType("System.Int32"));
9. table.Columns.Add("Name", Type.GetType("System.String"));
10.
11. //设置主键
12. table.PrimaryKey = new DataColumn[] { table.Columns["ID"] };
13. table.Columns["Id"].AutoIncrement = true;
14. table.Columns["Id"].AutoIncrementSeed = 1;
15. table.Columns["Id"].ReadOnly = true;
16. return table;
17. }
18.
19. public static void MakeData(DataTable table, int count)
20. {
21. if (table == null)
22. return;
23.
24. if (count <= 0)
25. return;
26.
27. DataRow row = null;
28.
29. for (int i = 1; i <= count; i++)
30. {
31. //创建一个新的DataRow对象(生成一个新行)
32. row = table.NewRow();
33. row["Name"] = "Test" + i.ToString();
34. //添加新的DataRow
35. table.Rows.Add(row);
36. }
37. }
38.}
public class Tools
{
public static DataTable MakeDataTable()
{
DataTable table = new DataTable();
//生成DataTable的模式(schema)
table.Columns.Add("Id", Type.GetType("System.Int32"));
table.Columns.Add("Name", Type.GetType("System.String"));
//设置主键
table.PrimaryKey = new DataColumn[] { table.Columns["ID"] };
table.Columns["Id"].AutoIncrement = true;
table.Columns["Id"].AutoIncrementSeed = 1;
table.Columns["Id"].ReadOnly = true;
return table;
}
public static void MakeData(DataTable table, int count)
{
if (table == null)
return;
if (count <= 0)
return;
DataRow row = null;
for (int i = 1; i <= count; i++)
{
//创建一个新的DataRow对象(生成一个新行)
row = table.NewRow();
row["Name"] = "Test" + i.ToString();
//添加新的DataRow
table.Rows.Add(row);
}
}
}
使用Log4net记录日志，默认插入记录数为40000条，每次插入1条，可在界面修改，使用System.Diagnostics.StopWatch记录插入时间，每次测试后删除原表重建
窗体代码如下：
[c-sharp]www.nuoya118.com
public delegate bool InsertHandler(DataTable table, int batchSize); public partial class FrmBatch : Form { private Stopwatch _watch = new Stopwatch(); public FrmBatch() { InitializeComponent(); } private void FrmBatch_Load(object sender, EventArgs e) { txtRecordCount.Text = "40000"; txtBatchSize.Text = "1"; } //逐条数据插入 private void btnInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteInsert, "Use SqlServer Insert"); } //拼接sql语句插入 private void btnBatchInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteBatchInsert, "Use SqlServer Batch Insert"); } //拼接sql语句并使用Transaction private void btnTransactionInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteTransactionInsert, "Use SqlServer Batch Transaction Insert"); } //拼接sql语句并使用SqlTransaction private void btnSqlTransactionInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteSqlTransactionInsert, "Use SqlServer Batch SqlTransaction Insert"); } //使用DataAdapter private void btnDataAdapterInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteDataAdapterInsert, "Use SqlServer DataAdapter Insert"); } //使用TransactionScope private void btnTransactionScopeInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteTransactionScopeInsert, "Use SqlServer TransactionScope Insert"); } //使用表值参数 private void btnTableTypeInsert_Click(object sender, EventArgs e) { Insert(DbOperation.ExecuteTableTypeInsert, "Use SqlServer TableType Insert"); } private DataTable InitDataTable() { DataTable table = Tools.MakeDataTable(); int count = 0; if (int.TryParse(txtRecordCount.Text.Trim(), out count)) { Tools.MakeData(table, count); //MessageBox.Show("Data Init OK"); } return table; } public void Insert(InsertHandler handler, string msg) { DataTable table = InitDataTable(); if (table == null) { MessageBox.Show("DataTable is null"); return; } int recordCount = table.Rows.Count; if (recordCount <= 0) { MessageBox.Show("No Data"); return; } int batchSize = 0; int.TryParse(txtBatchSize.Text.Trim(), out batchSize); if (batchSize <= 0) { MessageBox.Show("batchSize <= 0"); return; } bool result = false; _watch.Reset(); _watch.Start(); result = handler(table, batchSize); _watch.Stop(www.nuoya66.com); string log = string.Format("{0};RecordCount:{1};BatchSize:{2};Time:{3};", msg, recordCount, batchSize, _watch.ElapsedMilliseconds); LogHelper.Info(log); MessageBox.Show(result.ToString()); } }
