SQL INNER JOIN - 選擇數據基於價值的另一行

Question

難的另一個表來解釋我的問題，但我會盡我所能...

我試圖建立各種表的視圖，但我需要兩個額外的欄目「HomeTeamID」和「AwayTeamID」，即使對於該特定事件的其他市場，也會帶來適當的ID。

我已經附加數據告訴你什麼是我想要實現（電子表格here）

Answer 1

你必須加入2倍，

SELECT HomeTeam.ID, AwayTeam.ID from xyz INNER JOIN Team as HomeTeam on Team.ID = HomeTeam.ID INNER JOIN Team as AwayTeam on Team.ID = AwayTeam.ID 

Answer 2

覺得我我知道了，但又遇到了另一個問題。如果我不在SELECT區域包含HomeTeamID，則需要23秒。當我包含HomeTeamID時，出現以下錯誤：

'無法爲數據庫'tempdb'中的對象'dbo.SORT臨時運行存儲：140737648001024'分配空間，因爲'PRIMARY'文件組已滿。通過刪除不需要的文件，刪除文件組中的對象，向文件組添加其他文件或爲文件組中的現有文件設置自動增長來創建磁盤空間。 '

由於受到限制，Visual Studio在Parallels中的Windows 8.1內部運行，我只有1GB的備用磁盤空間。該表本身有大約50,000條記錄共（中密度纖維板/ LDF文件僅40MB，所以我努力看是什麼問題？/
