为什么我的代码被忽略了？

Question

当我执行时，唯一有效的是邮政编码。它没有给我一个大于 08/01/16 或我的账单提供商的服务日期。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："And" 比 "or" 绑定得更紧密。也就是说，只有第一个 zip-code 比较会与其余 "and" 条件进行评估。其余的是“或”，如果它们匹配，您将获得记录。

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

Answer 2

您可以使用 (...) 作为 n8wrl 显示或以下，我认为这样会更快。

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

问题可能是因为您漏掉了一些括号。请注意 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，例如 zip LIKE '12345%'
