如何在SQL中使用另一列的內容將數據從一列拆分為單獨的列

Question

我有一個具有以下布局的表：

RecordID    OptionID    StudentID   ClassID DEMOGRAPHIC     DemographicOption
74276205    1283131     20348031    1766586 REGION          East
74276205    866932      20348031    1766586 OFFICE          Boston
74276205    867044      20348031    1766586 CAREER_LEVEL    Manager
74276205    867016      20348031    1766586 FSS             Con
74276205    867073      20348031    1766586 SERVICE_AREA    Human Capital
74276205    1196052     20348031    1766586 SERVICE_LINE    HR Transformation
74276205    1264928     20348031    1766586 INDUSTRY        Life Sciences 

我需要使用人口統計列，並從與人口統計列中的標簽相對應的結果中分離出單獨的列。

我該怎么做呢？我嘗試了幾件事，最終結果分別放在不同的行上，但是我需要將數據放在一行上，如下所示：

RecordID    OptionID    StudentID   ClassID DEMOGRAPHIC REGION  OFFICE  CAREER_LEVEL    FSS SERVICE_AREA    SERVICE_LINE        INDUSTRY
74276205    1283131     20348031    1766586 REGION      East    Boston  Manager         Con Human Capital   HR Transformation   Life Sciences

任何幫助，我們將不勝感激。
