如何使用AND使用IN子句過濾多列

Question

我正在嘗試根據多個可能的值來過濾幾列中的數據。 如果我使用下面的語句，則會得到匹配的結果，但結果太多。 例如，如果我僅傳遞Status [Lead，Customer]，則僅獲得這些記錄。 如果我添加SalesRep [cary]，那么我還將獲得所有匹配的Cary記錄，其中包括一些具有其他狀態的記錄，例如Prospect。

SELECT id, `ContactID`, Status, SalesRep, LeadSource, `PhysicalAddress_State`, `PhisicalAddress_Zip`  FROM Contacts WHERE
Status IN ('Lead','customer') OR
SalesRep IN('cary') OR
LeadSource IN ('') OR
PhysicalAddress_State IN ('') OR
PhisicalAddress_Zip IN ('');

我要查找的是AND，因此我只會得到同時匹配Status [Lead，Customer]和SalesRep [cary]的記錄

SELECT id, `ContactID`, Status, SalesRep, LeadSource, `PhysicalAddress_State`, `PhisicalAddress_Zip`  FROM Contacts WHERE
Status IN ('Lead','customer') AND
SalesRep IN('cary') AND
LeadSource IN ('') AND
PhysicalAddress_State IN ('') AND
PhisicalAddress_Zip IN ('');

但是，如果我將OR更改為AND，除非沒有為每個字段進行選擇，否則我不會獲得任何記錄。 如果我沒有搜索價值，該如何獲得AND工作？

我想出了一種方法，可以將不包含在其中的字段包括在內：

SELECT id, `ContactID`, Status, SalesRep, LeadSource, `PhysicalAddress_State`, `PhisicalAddress_Zip`  FROM Contacts WHERE
IF(true, Status IN ('Closed'), id != 0) AND
IF(true, SalesRep IN('Cary'), id != 0) AND
IF(false, LeadSource IN (''), id != 0) AND
IF(false, PhysicalAddress_State IN (''), id != 0) AND
IF(true, PhisicalAddress_Zip IN ('87123'), id != 0);

對於我的環境：

SELECT id, `ContactID`, Status, SalesRep, LeadSource, `PhysicalAddress_State`, `PhisicalAddress_Zip`  FROM Contacts WHERE
IF(:includeStatus, Status IN :status, id != 0) AND
IF(:includeSalesRep, SalesRep IN :SalesRep, id != 0) AND
IF(:includeLeadSource, LeadSource IN :LeadSource, id != 0) AND
IF(:includePhysicalAddress_State, PhysicalAddress_State IN :PhysicalAddress_State, id != 0) AND
IF(:includePhisicalAddress_Zip, PhisicalAddress_Zip IN :PhisicalAddress_Zip, id != 0);
