⑴ sql 最小值選取
select min(left_day),atrate from Act_Table
where Act=1 group by atrate
⑵ SQL從查詢結果中查最小值
SELECT C.CategoryID, C.CategoryName, SUM(F.CommentNO) AS SumComment
FROM Category AS C, Feedback AS F, Article AS A
WHERE C.CategoryID=A.CategoryID AND A.ArticleID=F.ArticleID
GROUP BY C.CategoryID, C.CategoryName having SUM(F.CommentNO)=
(select min(t1.SumComment1) from
(SELECT SUM(F.CommentNO) AS SumComment1
FROM Category AS C, Feedback AS F, Article AS A
WHERE C.CategoryID=A.CategoryID AND A.ArticleID=F.ArticleID
GROUP BY C.CategoryID, C.CategoryName) as t1)
這樣試試
⑶ 頁面搜索時SQL表中都多條相同的數據 怎麼只選擇序號最小的這條
selecttop1*fromhyzwherename='%"+name+"%'
⑷ sql 語句 一列中的最小值
select riqi, from table_name where =(select min() from table_name where riqi between '20000101' and '20000131')
⑸ oracle sql查詢完成分組並只返回每組的最小最大值
我的測試表裡有7條數據。每3條數據分作一組求最小和最大id。
WITHtmp("id")AS
(SELECT1FROMDUALUNIONALL
SELECT2FROMDUALUNIONALL
SELECT3FROMDUALUNIONALL
SELECT4FROMDUALUNIONALL
SELECT5FROMDUALUNIONALL
SELECT6FROMDUALUNIONALL
SELECT7FROMDUAL
)
selectmin("id")min_id,max("id")max_id
from(
select"id",row_number()over(orderby"id")seqfromtmp
)t
groupbyfloor((seq-1)/3)
orderbyfloor((seq-1)/3)結果如下：
樓主把上面語句里的3換成100就行了。
⑹ sql 幾個欄位最小值
我只寫6個欄位,你可以擴展
select case when jiage_k> jiage_c then jiage_c else jiage_k end as jiage_min from (
select case when jiage_a> jiage_b then jiage_b else jiage_a end as jiage_k,jiage_c from (
select case when jiage1>jiage2 then jiage2 else jiage1 end as jiage_a,
case when jiage3>jiage4 then jiage3 else jiage4 end as jiage_b,
case when jiage5>jiage6 then jiage5 else jiage6 end as jiage_c
from 表名) a
) b
這樣就可以查出沒行記錄中最小的值是多少 那如果還想知道欄位名 可以left join 並且用case去對比就知道了
⑺ 如何刪除sql中某個欄位出現重復的數據，且只保留id最小的
⑻ 如何在SQL中搜尋表中最小和第二小的數據我可以排序出來 但是目標是只要這2條記錄~
最小：
SELECT MIN（欄位）
FROM 表
第二小：
SELECT MIN（欄位）
FROM 表
WHERE 欄位>(SELECT MIN（欄位）FROM 表)
兩個都要：
SELECT TOP 2 欄位
FROM 表
ORDER BY 欄位
⑼ sql 取分組 最小值
select USERTYPE from CONFIG_USER group by USERTYPE ORDER BY USERTYPE DESC
先分組再排序 取第一個就行了
⑽ SQL取出值最小的一條數據
補充樓上：
select min(欄位名稱）as 最小值 from 表名
