PairWise subquery:
e.g.:
select * from wf_docsort where (ndocsortid,nmoduleinfoid) in (select ndocsortid, nmoduleinfoid from wf_docsort where instr(cname,'文')>0)
the above sql is the same function as:
select * from wf_docsort where ndocsortid = (select ndocsortid from wf_docsort where ......
Group functions
SELECT [column,] group_function(column) ... from table [WHERE condition] [GROUP BY group_by_expression] [ORDER BY column];
e.g.:
SELECT department_id, job_id, SUM(salary), COUNT(employee_id) from employees GROUP BY department_id, job_id ;
SELECT [column,] group_function(column).. ......

1.cross join 全外连接(笛卡尔乘积)
SELECT A.*, B.* from A FULL OUTER JOIN B ON A.ID = B.ID
2.inner join 内连接(在笛卡尔乘积的结果集中去掉不符合连接条件的行)
SELECT A.* from A INNER JOIN B ON A.ID=B.ID
3.left outer join 左外连接(在inner join的结� ......
