如何在SQL中选择表的最后一条记录?

这是一个从表中选择所有记录的示例代码。有人能告诉我如何选择该表的最后一条记录吗?

select * from table

当我使用:选择*从表顺序由ID DESC限制第1行:'LIMIT'附近的语法不正确。这是我使用的代码:

private void LastRecord()
{
    SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["HELPDESK_OUTLOOKConnectionString3"].ToString());

    conn.Open();
    SqlDataReader myReader = null;
    SqlCommand myCommand = new SqlCommand("SELECT * FROM HD_AANVRAGEN ORDER BY " +
                "aanvraag_id DESC LIMIT 1", conn);
    myReader = myCommand.ExecuteReader();
    while (myReader.Read())
    {
        TextBox1.Text = (myReader["aanvraag_id"].ToString());
        TextBox1.Text += (myReader["wijziging_nummer"].ToString());
        TextBox1.Text += (myReader["melding_id"].ToString());
        TextBox1.Text += (myReader["aanvraag_titel"].ToString());
        TextBox1.Text += (myReader["aanvraag_omschrijving"].ToString());
        TextBox1.Text += (myReader["doorlooptijd_id"].ToString());
        TextBox1.Text += (myReader["rapporteren"].ToString());
        TextBox1.Text += (myReader["werknemer_id"].ToString());
        TextBox1.Text += (myReader["outlook_id"].ToString());
    }
}

其他回答

如果你有一个自增字段(比如ID)，那么你可以这样做: SELECT * FROM foo WHERE ID = (SELECT max(ID) FROM foo)

要获取sql数据库的最后一行，请使用以下sql字符串:

SELECT * FROM TableName WHERE id=(SELECT max(id) FROM TableName);

输出:

最后一行你的数据库!

在没有任何进一步信息的情况下，我们能做的最好的数据库是什么

Sql Server

SELECT TOP 1 * FROM Table ORDER BY ID DESC

MySql

SELECT * FROM Table ORDER BY ID DESC LIMIT 1

SELECT * FROM table ORDER BY Id DESC LIMIT 1

2011-03-04 08:49:29

select ADU.itemid, ADU.startdate, internalcostprice 
from ADUITEMINTERNALCOSTPRICE ADU

right join

   (select max(STARTDATE) as Max_date, itemid 
   from ADUITEMINTERNALCOSTPRICE
   group by itemid) as A

on A.ITEMID = ADU.ITEMID
and startdate= Max_date
