匹配多行一個表與另一個表的多個列的MySQL

第一個表：聯繫人列：

Customer ID,Project ID1,Project ID2,Project ID3

這樣一個聯繫方式將具有一行。

第二表：時間表列

Project ID, Name, Owner, Hours

一個接觸可以有多個項。

我想匹配時間表中的項目ID到3列聯繫人表。

我正在使用以下查詢。

SELECT "Customer ID","Project ID","Project Name","Owner", 
     "Hours","Approval Status","Status","Project Manager", 
     "Sales Person","Account Manager","Discount %","Hourly Rate", 
     "Monthly Budget","Total Budget" 
FROM "Timesheets" 
    LEFT JOIN "Contacts (Boost Media Group)" 
     ON "Timesheets"."Project ID" = "Contacts (Boost Media Group)"."Zoho Projects ID 1";

但它沒有返回所需的結果，因爲我無法使用聯繫人表的項目ID2，項目ID3來檢查它。

任何建議如何解決這個問題？

雙引號maches？你確定？？ – RiggsFolly

你真的**有像'Contacts（Boost Media Group）' – RiggsFolly

這樣的表名和'Zoho Projects ID 1'這樣的列名'' – RiggsFolly

糾正我，如果我錯了。我想你希望他們在任何條件（百會項目編號3或Zoho項目ID 2或Zoho項目ID 1）與「時間表」，「項目ID」，圍繞列名

SELECT "Customer ID","Project ID","Project Name","Owner", 
     "Hours","Approval Status","Status","Project Manager", 
     "Sales Person","Account Manager","Discount %","Hourly Rate", 
     "Monthly Budget","Total Budget" 
FROM "Timesheets" 
    LEFT JOIN "Contacts (Boost Media Group)" 
     ON "Timesheets"."Project ID" = "Contacts (Boost Media Group)"."Zoho Projects ID 1" 
or "Timesheets"."Project ID" = "Contacts (Boost Media Group)"."Zoho Projects ID 2" 
or "Timesheets"."Project ID" = "Contacts (Boost Media Group)"."Zoho Projects ID 3"
