在Asp.Net中使用事务
private string mConnStr = ConfigurationManager.ConnectionStrings["ConnStr"].ToString();

using (OracleConnection vConn=new OracleConnection(mConnStr))

foreach (string vSql in vSqlList)

{

vCmd.CommandText = vSql;

vCmd.ExecuteNonQuery();

}

vTrans.Commit();

}

catch (Exception ex)

{

vTrans.Rollback();

}

}

SqlConnection conn = new SqlConnection(connString);
