Question

当我执行时，唯一有效的是Zipcodes。它没有给我一个大于08/01/16的服务日期或我的结算提供商。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”绑定比“或”更紧密。也就是说，只有第一个邮政编码比较与其他“和”条件一起评估。其余的是“或”，如果匹配，你就会得到记录。

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

你可以使用(...)作为n8wrl节目或以下内容，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

问题可能是因为你遗漏了一些括号。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

我认为你打算写

A AND B AND (zip1 OR zip2 OR zip3)

其中A，B，zip1，...是布尔条件，如zip LIKE '12345%'

为什么我的代码被忽略了？
