Oracle排序分页查询和MySQL数据库的语句还不一样，这里做简单的记录。
按操作时间排序1
SELECT A.*, ROWNUM RN FROM (SELECT * FROM v_log) A ORDER BY operatetime DESC 结果
可以发现，按时间排序了，但是rownum并不是从小到大，因为oracle是先生成rownum，再进行排序，需要在套一层查询
按操作时间排序2
SELECT T.*, rownum RN FROM(SELECT * FROM (SELECT * FROM v_log) ORDER BY operatetime DESC ) T结果：
顺序正确，rownum正确，在此基础上再套一层查询进行分页
按操作时间排序并分页
SELECT T2.* from(
SELECT T.*, rownum RN FROM(
SELECT * FROM (SELECT * FROM v_log) ORDER BY operatetime DESC
)T) T2 WHERE RN BETWEEN 1 and 10
测试
SELECT * FROM (SELECT A."sku", ROWNUM rn, A."goods_sn" FROM AMZ_HUOPIN_SKU AWHERE ROWNUM <= 10 ORDER BY A."goods_sn" DESC) temp
WHERE temp.rn > 0;SELECT A."sku", A."goods_sn", ROWNUM RN FROM AMZ_HUOPIN_SKU A ORDER BY A."sku" DESC## 子查询先找出所有，然后再rownum,rownum 为伪列，后再排序
SELECT A."sku", A."goods_sn", ROWNUM RN FROM (SELECT * FROM AMZ_HUOPIN_SKU) A ORDER BY A."sku" DESC## 因为oracle是先生成rownum，再进行排序，需要在套一层查询,即先拍好序，然后再生成rownum
SELECT T."sku", T."goods_sn", ROWNUM RN FROM (SELECT * FROM (SELECT * FROM AMZ_HUOPIN_SKU) ORDER BY "sku" DESC
) T## 上边的这两个语句是等价的
SELECT T."sku", T."goods_sn", ROWNUM RN FROM (SELECT * FROM AMZ_HUOPIN_SKU ORDER BY "sku" DESC
) TSELECT T2.* FROM(
SELECT T."sku", T."goods_sn", ROWNUM RN FROM (SELECT * FROM AMZ_HUOPIN_SKU ORDER BY "sku" DESC
) T) T2 WHERE RN BETWEEN 0 AND 10综合查询
# 1、子句查询，这条语句可以加条件WHERE
SELECT * FROM (SELECT A."sku", A."goods_sn", A."category",A."color_name", A."size_name", A."fnsku",H.QTY,H.WAREHOUSEID,H.F_CREATE_TIME FROM AMZ_HUOPIN_SKU A
LEFT JOIN HWC_CAMEL_INV_ALL H ON A."fnsku" = H.SKU)# 2、排序SELECT * FROM (SELECT * FROM (SELECT A."sku", A."goods_sn", A."category",A."color_name", A."size_name", A."fnsku",H.QTY,H.WAREHOUSEID,H.F_CREATE_TIME FROM AMZ_HUOPIN_SKU A
LEFT JOIN HWC_CAMEL_INV_ALL H ON A."fnsku" = H.SKU)) ORDER BY "goods_sn" DESC# 3、排序之后，再获取ROWNUM
SELECT T.*, ROWNUM RN FROM (SELECT * FROM (SELECT * FROM (SELECT A."sku", A."goods_sn", A."category",A."color_name", A."size_name", A."fnsku",H.QTY,H.WAREHOUSEID,H.F_CREATE_TIME FROM AMZ_HUOPIN_SKU A
LEFT JOIN HWC_CAMEL_INV_ALL H ON A."fnsku" = H.SKU)) ORDER BY "goods_sn" DESC) T# 4、再根据获取到的ROWNUM按照顺序进行分页
SELECT R.* FROM(SELECT T.*, ROWNUM RN FROM (SELECT * FROM (SELECT * FROM (SELECT A."sku", A."goods_sn", A."category",A."color_name", A."size_name", A."fnsku",H.QTY,H.WAREHOUSEID,H.F_CREATE_TIME FROM AMZ_HUOPIN_SKU A LEFT JOIN HWC_CAMEL_INV_ALL H ON A."fnsku" = H.SKU WHERE A."goods_sn" = 'K832026565')) ORDER BY "goods_sn" DESC) T
) R WHERE RN BETWEEN 10 AND 20注：本文为转载，原文地址：oracle先排序再分页
