在數據庫連接上創建事務處理對象,然後調用事務處理對象來提交事務或回滾事務。簡單的代碼:
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();
//啟用事務
SqlTransaction tran = conn.BeginTransaction();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.Transaction = tran;
try
{
cmd.CommandText = "UPDATE HRRollMain Set TotalMember=TotalMember-100 WHERE RollID = '2005070101'";
cmd.ExecuteNonQuery();
cmd.CommandText = "UPDATE HRRollSum Set TotalSumMember=TotalSumMember+100 WHERE RollSumID = '20050701'";
cmd.ExecuteNonQuery();
tran.Commit();
MessageBox.Show("事務提交成功!");
}
catch(Exception ex)
{
tran.Rollback();
MessageBox.Show("Error!"+ex.Message);
}
}
