Question

SELECT * 
FROM orders
WHERE date_ord >=  '2015-02-16'
AND date_ord <=  '2015-02-26'
AND active =1
AND (
(
ship_city =  'NYC'
OR ship_city =  'New York'
OR ship_city =  'New York City'
)
AND ship_state =  'NY'
)
OR (
(
bill_city =  'NYC'
OR bill_city =  'New York'
OR bill_city =  'New York City'
)
AND ship_state =  ''
)
ORDER BY ordId

客户已添加＆＃34;纽约＆＃34;城市名称有三种变体，如＆＃34; NYC＆＃34;，＆＃34;纽约＆＃34;和＃34;纽约市＆＃34;。我需要查询所有这些记录，其中结算城市是全部3种变化，并且运输状态为空或NULL，并且使用城市名称和运输状态的所有3种变体的运输城市是纽约的那些记录被设置为＆＃39; NY＆＃39 ;。简而言之，所有运往纽约市的订单。（账单状态可以是CA或FL）

此查询并不完美。我的记录超过了日期范围。请建议修复此问题。

根据@Ash和@DovesandChicks的建议，我尝试使用IN函数

SELECT * 
FROM orders
WHERE date_ord >=  '2015-02-16'
AND date_ord <=  '2015-02-26'
AND active =1
AND ship_city
IN ('NYC',  'New York',  'New York City')
OR (bill_city IN ('NYC',  'New York',  'New York City') AND ship_state =  'Unlisted')
ORDER BY ordId

查询仍有问题。请帮忙

Answer 1

看起来你在OR附近有不必要的括号

SELECT * 
FROM orders
WHERE date_ord >=  '2015-02-16'
AND date_ord <=  '2015-02-26'
AND active =1
AND (
        (
            ship_city =  'NYC'
            OR ship_city =  'New York'
            OR ship_city =  'New York City'
        )
        AND ship_state =  'NY'

    --)
        OR 
    --(

        (
            bill_city =  'NYC'
            OR bill_city =  'New York'
            OR bill_city =  'New York City'
        )
        AND ship_state =  ''
    )
ORDER BY ordId

通过适当的格式化，查询更具可读性

条件可以通过这种方式简化：

SELECT * 
FROM orders
WHERE date_ord >=  '2015-02-16'
AND date_ord <=  '2015-02-26'
AND active =1
AND ship_city in  ('NYC','New York','New York City')
AND ship_state in ('NY','')
ORDER BY ordId

Answer 2

1）你可以使用
AND ship_city IN（'NYC'，'New York'，'New York City'） 2）你的OR条款没有足够的括号。您需要在一个括号中包含所有OR

所以

WHERE（日期位） AND（带有OR的城市位）

如果你需要我，我可以写出来：

    SELECT * FROM tblorders 
WHERE dateord >= '2015-02-16' 
AND dateord <= '2015-02-26' 
AND activeFlag =1 
AND (s_city IN ( 'NYC', 'New York', 'New York City' ) OR ( b_city IN ( 'NYC', 'New York', 'New York City' ) AND s_state = 'Unlisted' )) 
ORDER BY ordId

查询以获得城市名称的3种变体
