Question

我尝试编写SQL查询以从表中排除某些参数。这是我的疑问：

SELECT  RULE_NAME AS "Rule Name", COUNT( RULE_NAME ) AS "Event_cnt" 
FROM EVENTS_VW
WITH (NOLOCK) 
WHERE RULE_NAME LIKE
('Reporting_%')
 AND EVENT_DT >=  '2016-12-01 00:00:00.0' AND EVENT_DT <= '2016-12-31 00:00:00.0'
GROUP BY RULE_NAME ORDER BY EVENT_CNT DESC

我想在上述查询中排除的规则是：

Reporting_deleted_mail
Reporting_fwd_mail

如何修改上述查询以适应我试图排除的两条规则？

Answer 1

将此添加到WHERE子句中（在GROUP BY子句之前）：

AND RULE_NAME NOT IN ('Reporting_deleted_mail', 'Reporting_fwd_mail')

Answer 2

WHERE RULE_NAME LIKE ('Reporting_%') 
AND RULE_NAME NOT IN ('Reporting_deleted_mail', 'Reporting_fwd_mail')

Answer 3

我感谢您的快速反馈。最终的解决方案是：

SELECT  
   RULE_NAME AS "Rule Name", 
   COUNT( RULE_NAME ) AS "Event_cnt" 
FROM 
   EVENTS_VW WITH (NOLOCK) 
WHERE 
   RULE_NAME LIKE ('Reporting_%') 
   AND RULE_NAME NOT IN ('Reporting_deleted_mail', 'Reporting_fwd_mail')
    AND EVENT_DT >=  '2016-12-01 00:00:00.0' AND EVENT_DT <= '2016-12-31 00:00:00.0'
GROUP BY 
   RULE_NAME 
ORDER BY 
   EVENT_CNT DESC
