Sql 根据Oracle中的字段值插入记录数
我有以下脚本:-Sql 根据Oracle中的字段值插入记录数,sql,oracle,Sql,Oracle,我有以下脚本:- SELECT quoteid, tariff_length, cost FROM tblquotesnew q LEFT JOIN tbltariffsnew t ON q.tariff_id = t.tariff 这可能会返回如下结果:- quoteid tariff_length cost 310 4 12 311 6 16 是否可以将行插入一个单
SELECT
quoteid,
tariff_length,
cost
FROM
tblquotesnew q
LEFT JOIN
tbltariffsnew t
ON q.tariff_id = t.tariff
这可能会返回如下结果:-
quoteid tariff_length cost
310 4 12
311 6 16
是否可以将行插入一个单独的表中,其中插入的行数基于U长度
因此,使用上述方法,插入表tblcommnew如下所示
commid quoteid cost
1 310 12
2 310 12
3 310 12
4 310 12
5 311 16
6 311 16
7 311 16
8 311 16
9 311 16
10 311 16
这里有一个选择:
SQL> with test (quoteid, tariff_length, cost) as
2 (select 310, 4, 12 from dual union
3 select 311, 6, 16 from dual
4 )
5 select rownum as commid, quoteid, cost
6 from test,
7 table(cast(multiset(select level from dual
8 connect by level <= tariff_length
9 ) as sys.odcinumberlist));
COMMID QUOTEID COST
---------- ---------- ----------
1 310 12
2 310 12
3 310 12
4 310 12
5 311 16
6 311 16
7 311 16
8 311 16
9 311 16
10 311 16
10 rows selected.

@Littlefoot方法的一个细微变化是使用XMLTable生成组合:
with tblquotesnew (quoteid, tariff_length, cost) as (
select 310, 4, 12 from dual
union all select 311, 6, 16 from dual
)
select rownum as commid, quoteid, cost
from tblquotesnew
cross join xmltable ('1 to xs:integer($n)' passing tariff_length as "n");
COMMID QUOTEID COST
---------- ---------- ----------
1 310 12
2 310 12
3 310 12
4 310 12
5 311 16
6 311 16
7 311 16
8 311 16
9 311 16
10 311 16
作为插入,您只需执行以下操作:
insert into tblcommnew (commid, quoteid, cost)
select rownum, quoteid, cost
from tblquotesnew
cross join xmltable ('1 to xs:integer($n)' passing tariff_length as "n");
10 rows inserted.
