csdn问题锦集之一(Oracle部分)(总结)

数据库表table里有id   name   banben(版本)(该列值为数字)三列
其中id唯一,name不唯一,banben不唯一,但是name和banben组合起来是唯一的,找出name=gis且banben(版本)的数值最高的行的id
SELECT ID,NAME,BANBEN
FROM   TABLENAME A INNER JOIN (
                         SELECT MAX(BANBEN) OVER(PARTITION BY NAME ORDER BY NAME) AS MAXBANBEN,
                         ROWID AS RID
                         FROM   TABLENAME
                         WHERE  NAME = 'gis'
                        ) B ON A.ROWID = B.RID AND A.SAL = B.MAXBANBEN
