SELECT 1, 2, 3
UNION ALL SELECT 4, 5, 6
UNION ALL SELECT 7, 8, 9

SELECT * 
FROM DUAL 
CONNECT BY ROWNUM <= 9;

试试oracle中的connect by子句，就像这样

select level,level+1,level+2 from dual connect by level <=3;

下面是我如何使用一个简洁的XML技巧在Oracle 10+中填充静态数据。

create table prop
(ID NUMBER,
 NAME varchar2(10),
 VAL varchar2(10),
 CREATED timestamp,
 CONSTRAINT PK_PROP PRIMARY KEY(ID)
);

merge into Prop p
using (
select 
  extractValue(value(r), '/R/ID') ID,
  extractValue(value(r), '/R/NAME') NAME,
  extractValue(value(r), '/R/VAL') VAL
from
(select xmltype('
<ROWSET>
   <R><ID>1</ID><NAME>key1</NAME><VAL>value1</VAL></R>
   <R><ID>2</ID><NAME>key2</NAME><VAL>value2</VAL></R>
   <R><ID>3</ID><NAME>key3</NAME><VAL>value3</VAL></R>
</ROWSET>
') xml from dual) input,
 table(xmlsequence(input.xml.extract('/ROWSET/R'))) r
) p_new
on (p.ID = p_new.ID)
when not matched then
insert
(ID, NAME, VAL, CREATED)
values
( p_new.ID, p_new.NAME, p_new.VAL, SYSTIMESTAMP );

merge只插入原始表中缺少的行，这很方便 如果您想重新运行插入脚本。

SELECT 1, 2, 3
UNION ALL SELECT 4, 5, 6
UNION ALL SELECT 7, 8, 9

下面的裸值命令为我在PostgreSQL工作:

VALUES (1,2,3), (4,5,6), (7,8,9)
