我有三个表格,在这里汇总到相关列(从原始帖子8/20/14修改):
有5个唯一的CODES.WAGECODE记录,每个记录都有描述。 有5个唯一的EMP.EMPCODE,包含名字和姓氏
EMPWAGE表应该有5个EMP.EMPCODE(25条记录)中的每条记录
我在SQLFiddle上的架构包含了16条所需的记录,还需要9条记录。 我有以下代码隔离了9条记录所需的数据:
SELECT E.EMPCODE, C.WAGECODE, C.DESCRIPTION, E.FIRSTNAME, E.LASTNAME
FROM
(EMP E CROSS JOIN CODES C)
LEFT JOIN EMPWAGE EW ON E.EMPCODE = EW.EMPCODE AND C.WAGECODE = EW.WAGECODE
WHERE NOT EXISTS
(SELECT 1
FROM EMPWAGE EW
WHERE
E.EMPCODE = EW.EMPCODE AND C.WAGECODE = EW.WAGECODE
)
但是我坚持使用SQLFiddle插入此数据(9条记录)的过程: http://sqlfiddle.com/#!3/7cfe7/7,我将不胜感激。
将以下内容添加到上面的第一行,我的SQLFiddle在运行
后保持不变INSERT INTO EMPWAGE (EMPCODE, WAGECODE, DESCRIPTION, FIRSTNAME, LASTNAME)
用于SQLFiddler http://sqlfiddle.com/#!3/7cfe7/7的架构:

CREATE TABLE EMP (EMPCODE varchar(11) NOT NULL, FIRSTNAME varchar(15) NULL,
LASTNAME varchar(15) NULL);
Insert into EMP values ('BretV', 'Bret', 'Vick');
