为什么我的代码被忽略？

Question

当我执行唯一工作的是Zipcodes。它不会给我的服务日期大于08/01/16或我的结算提供商。我不知道为什么。

SELECT Name, BirthDate, Address1, Address2, City, StateProvince, ZipCode, BillingProviderID, ServiceDate, ChargeCatID 
FROM dbo.PbrChargeTransactions 
WHERE ChargeCatID = 'EM' 
AND ServiceDate >= '08/01/16' 
AND BillingProviderID IN ('AAD.FD','DSD.DFD','ASDF.DD') 
AND ZipCode Like '68730%' 
OR ZipCode Like '68792%' 
OR ZipCode Like '68739%' 
OR ZipCode Like '68718%' 
OR ZipCode Like '57069%' 
OR ZipCode Like '57031%' 
OR ZipCode Like '57078%' 
OR ZipCode Like '57066%' 
OR ZipCode Like '57063%' 
OR ZipCode Like '57037%' 
OR ZipCode Like '57073%' 
OR ZipCode Like '57029%' 
OR ZipCode Like '57070%' 
ORDER BY Name 

Answer 1

运算符优先级：“和”的绑定比“或”更紧密。也就是说，只有第一个邮政编码比较用您的“和”条件的其余部分进行评估。其余的都是'OR'，如果他们匹配，你会得到记录。

试试这个：

SELECT Name, BirthDate, Address1, Address2, City, StateProvince, ZipCode,  BillingProviderID, ServiceDate, ChargeCatID 
FROM dbo.PbrChargeTransactions 
WHERE ChargeCatID = 'EM' 
AND ServiceDate >= '08/01/16' 
AND BillingProviderID IN ('AAD.FD','DSD.DFD','ASDF.DD') 
AND (ZipCode Like '68730%' 
OR ZipCode Like '68792%' 
OR ZipCode Like '68739%' 
OR ZipCode Like '68718%' 
OR ZipCode Like '57069%' 
OR ZipCode Like '57031%' 
OR ZipCode Like '57078%' 
OR ZipCode Like '57066%' 
OR ZipCode Like '57063%' 
OR ZipCode Like '57037%' 
OR ZipCode Like '57073%' 
OR ZipCode Like '57029%' 
OR ZipCode Like '57070%' 
) 
ORDER BY Name

您可以使用(...)作为n8wrl表演或以下，我认为会更快。

SELECT Name, BirthDate, Address1, Address2, City, StateProvince, ZipCode, BillingProviderID, ServiceDate, ChargeCatID 
FROM dbo.PbrChargeTransactions 
WHERE ChargeCatID = 'EM' 
AND ServiceDate >= '08/01/16' 
AND BillingProviderID IN ('AAD.FD','DSD.DFD','ASDF.DD') 
AND LEFT(ZipCode,5) in ('68730','68792','68739','68718','57069','57031', '57078','57066','57063','57037','57073','57029','57070') 
ORDER BY Name 

Answer 3

这个问题可能是因为你错过了一些括号。请注意的precedence of operators

如果你写

A AND B AND zip1 OR zip2 OR zip3 

这等于

((A AND B) AND zip1) OR zip2 OR zip3 

我想你打算写

A AND B AND (zip1 OR zip2 OR zip3) 

其中A，B，ZIP1 ，...是布尔条件，如zip LIKE '12345%'
