请问兄弟们这个SQL怎么写

[xxxzheng]

表table 1

DATE
2007-01-01
2007-01-02
.........
2007-01-30

表table2
empId date
jc001 2007-01-01
jc001 2007-01-02
jc001 2007-01-03
jc001 2007-01-08
jc001 2007-01-20
jc002 2007-01-01
jc002 2007-01-02
jc002 2007-01-02
jc003 2007-01-15
jc002 2007-01-30
....................
我想的结果是连个表进行连接查询
得到
DATE ID
2007-01-01 JC001
......... NULL
2007-01-30 JC001
2007-01-01 JC002
.................
2007-01-30 JC002

就是要一各整月数据，但T2中不是整月的就是NULL
T1 是各 日期表丛2007-01-01 --2007-01-30

请问这个SQL 怎么写

select table2.date as DATE,table2.empId as ID from table1 left join table2 on table1.DATE = table2.date order by table1.DATE;

说明白点

我觉得第一种方法比较好用。因为第二中方法在有的数据库中不支持。而第一个是标准的SQL语句到那都可以用

[wdman]

select table2.date,table2.id from table2 where table1.DATE =(+) table2.date order by table2.id

table1 左联table2
