我在看this link,但仍然无法创建我的陈述。我有以下查询
SELECT SUM(AMT) AS TOTAL, NAME, YEAR
FROM TABLE WHERE IND='ISVALID' GROUP BY NAME, YEAR
我会得到以下结果
TOTAL | NAME | YEAR
====================
10000 | JOHN | 2010
20500 | PETE | 2009
12500 | MIKE | 2008
50500 | MARY | 2008
50500 | MARY | 2007
40000 | JANE | 2007
我想排除50500 |玛丽| 2008年,它的IND列也带有'ISVALID'。我该怎么做?
答案 0 :(得分:3)
SELECT SUM(AMT) AS TOTAL, NAME, YEAR
FROM TABLE
WHERE IND='ISVALID' AND (NAME <> 'MARY' OR YEAR <> 2008)
GROUP BY NAME, YEAR
