通过ADO.NET实现事务处理
单的代码：
private void button1_Click(object sender, System.EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source=192.168.2.200;uid=sa;
password=;database = HaierHR");
conn.Open();
//启用事务
SqlTransaction tran = conn.BeginTransaction();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.Transaction = tran;
try
{
cmd.CommandText = "UPDATE HRRollMain Set TotalMember=TotalMember-100 WHE
RE RollID = '2005070101'";
cmd.ExecuteNonQuery();
cmd.CommandText = "UPDATE HRRollSum Set TotalSumMember=TotalSumMember+10
0 WHERE RollSumID = '20050701'";
cmd.ExecuteNonQuery();
tran.Commit();
MessageBox.Show("事务提交成功！");
}
catch(Exception ex)
{
tran.Rollback();
MessageBox.Show("Error!"+ex.Message);
}
}
