之前因为需要 在长传日志表中通过上传时间查询基础信息表 用到了这些语句
--根据公司查上传时间 select distinct aae036 from CJSCRZ where CJGS='A' --根据上传时间查乡镇编号 select distinct aae030 from CJSCRZ where aae036>=date'2014-12-26'and aae036<date'2014-12-27' --根据乡镇编号查乡镇 select * from ab01 w where w.aaf030 in (select distinct aae030 from CJSCRZ where aae036>=date'2014-12-26'and aae036<date'2014-12-27') --根据乡镇查各银行人数 select count(*) from ac01 where aaa148 like'41102317%'and yhmc =96288 select count(*) from ac01 where aaa148 like'41102317%'and yhmc =95580 select count(*) from ac01 where aaa148 like'41102314%'and yhmc =96288 --查60岁以上 select count(*) from ac01 a where a .aaa148 like'41102317%' and months_between(to_date('2014.12.29','yyyy.mm.dd'),a.aac006)>720 select count(*) from ac01 a where months_between(date'2014-12-27',a.aac006)>720 and a.aaa148 like'41102317%'
记下一些In的相关用法
SELECT "栏位名"
FROM "表格名"
WHERE "栏位名" IN ('值一', '值二', ...)
在Where子句中可以使用IN操作符来查询其列值在指定的列表中的行。比如:查询出工作职责是SALESMAN、PRESIDENT或者ANALYST的员工。条件有两种表示方法:
- WHERE job = 'SALESMAN ' OR job = 'PRESIDENT ' OR job = 'ANALYST '
- WHERE job IN ('SALESMAN', 'PRESIDENT', 'ANALYST')
代码演示:IN操作
SQL> SELECT ENAME,JOB,SAL FROM EMP 2 WHERE job IN ('SALESMAN', 'PRESIDENT', 'ANALYST');
7 rows selected |
对应IN操作的还有NOT IN,用法一样,结果相反。
