Oracle sql，選擇其他內容時選擇“第一行”

Question

我需要在下面的查詢中添加什么才能僅獲得此查詢后顯示的第一行？

查詢：

  SELECT column1,
         column2,
         MIN (column3),
         MIN (colmun4)
    FROM table
   WHERE column0 = 'value'
GROUP BY column1, column2

當前結果：

column1  column2  column3  column4
30187    C        201330   1/3/2013 2:49:35 PM    //I want this row only
33459    C        201330   1/3/2013 4:32:42 PM
90855    C        201390   3/28/2013 9:20:44 AM
96077    RA       201390   7/1/2013 11:31:46 AM

Answer 1

select * from (
SELECT column1,
         column2,
         MIN (column3),
         MIN (colmun4)
    FROM table
   WHERE column0 = 'value'
GROUP BY column1, column2)
where rownum = 1

或者，如果您使用的是oracle 12c，則可以使用以下代碼，

    SELECT column1,
             column2,
             MIN (column3),
             MIN (colmun4)
        FROM table
       WHERE column0 = 'value'
    GROUP BY column1, column2
OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY;
