你可以使用递归子查询分解子句将数据分割为任意数量：
WITH data ( "ORDER", article, size_1, size_2, size_3 ) AS (
SELECT * FROM qty_split
UNION ALL
SELECT "ORDER",
article,
GREATEST( size_1 - 99, 0 ),
GREATEST( size_2 - 99, 0 ),
GREATEST( size_3 - 99, 0 )
FROM data
WHERE size_1 > 99
OR size_2 > 99
OR size_3 > 99
)
SELECT "ORDER",
article,
LEAST( size_1, 99 ) AS size_1,
LEAST( size_2, 99 ) AS size_2,
LEAST( size_3, 99 ) AS size_3
FROM data
ORDER BY
"ORDER",
article,
ROWNUM;
其中，对于示例数据：
create table qty_split (
"ORDER" varchar2(4),
article_code varchar2(4),
size_1 number(3,0),
size_2 number(3,0),
size_3 number(3,0)
);
insert into qty_split
SELECT 'a001', '1111', 123, 165, 85 FROM DUAL UNION ALL
SELECT 'b002', '2222', 312, 45, 17 FROM DUAL UNION ALL
SELECT 'c003', '3333', 0, 0, 417 FROM DUAL;
输出：

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
