<if test="gid == 1"> </if>mybatis传入参数gid是字符串1，为什么不用加单引号

<foreach collection="consigneeGroupIds" item="gid" OPEN="(" SEPARATOR="," CLOSE=")"> #{gid} </foreach>

它使用了foreach标签来遍历集合consigneeGroupIds，并在每次迭代中生成一个gid的占位符。在生成的SQL语句中，gid会被替换为集合中的每个元素。整个表达式的作用是将consigneeGroupIds中的元素按照指定的格式连接起来...

public partial class chufang : Form { public chufang() { InitializeComponent(); } public int setpaid(string pid,string gid) { textBox1.Text = pid; textBox2.Text = gid; return 0; }

SELECT t1.gname,t1.tid,t1.gid, t1.score, t1.pics FROM game t1 INNER JOIN ( SELECT tid, MAX(score) AS max_score FROM game WHERE score != '评分过少' GROUP BY tid ) t2 ON t1.tid = t2.tid AND t1.score = t2.max_score INNER JOIN gameType t3 ON t1.tid = t3.tid WHERE t3.tname IN ( SELECT tname FROM user u INNER JOIN stock s ON u.uid = s.uid INNER JOIN game g ON s.gid = g.gid INNER JOIN gameType t ON g.tid = t.tid WHERE u.uid = (SELECT uid FROM user WHERE uname = 'admin') GROUP BY tname ) ORDER BY t1.gid;优化以上sql使其相同的tid只取一条

SELECT t1.gname, t1.tid, t1.gid, t1.score, t1.pics FROM ( SELECT gname, tid, gid, score, pics, ROW_NUMBER() OVER (PARTITION BY tid ORDER BY gid) AS rn FROM game WHERE score != '评分过少' ) t1 ...

这段代码是一个Java方法，用于根据商品ID查询商品信息。它使用了Apache Commons ...具体来说，这个方法接受一个字符串参数gid，表示商品ID，返回一个Goods对象，表示查询到的商品信息。如果查询失败，则返回null。

SELECT t1.gname, t1.score, t1.pics FROM game t1 INNER JOIN ( SELECT tid, MAX(score) AS max_score FROM game WHERE score != '评分过少' GROUP BY tid ) t2 ON t1.tid = t2.tid AND t1.score = t2.max_score INNER JOIN gameType t3 ON t1.tid = t3.tid WHERE t3.tname IN ( SELECT tname FROM user u INNER JOIN stock s ON u.uid = s.uid INNER JOIN game g ON s.gid = g.gid INNER JOIN gameType t ON g.tid = t.tid WHERE u.uid = (SELECT uid FROM user WHERE uname = 'admin') GROUP BY tname ) ORDER BY t1.gid;将以上sql优化，使得查出来的数据，相同的tname只留最小的gid的那一个数据

在优化后的查询语句中，我添加了一个子查询来获取每个 tid 对应的最小 gid，然后在主查询中加入条件 t1.gid = t2.min_gid 来确保只保留相同 tname 下的最小 gid 的数据。这样可以实现相同的 tname 只留下最小 gid 的...

<if test="gid != 1">，判断gid是否等于字符串1

这是一个条件判断语句，用于判断变量gid是否等于数字1。如果gid不等于1，则执行if语句中的代码块。注意，这里的1是数字类型而不是字符串类型。如果要判断gid是否等于字符串"1"，应该使用...<if test="gid != '1'">
