将列数据转换为列名

Question

这是我的表格“ sample1”

Title          Frequency   Month1      Month2     Month3  Month 4
tution_fee      monthly     april        may       june    july
net_fee         monthly     april        may       june    july
misc            annually    april        may       june    july

我应该得到一张这样的桌子

tution_fee    net_fee      misc
april        april        april
may          may          may       
june         june         june
july         july         july

随着我向其中添加数据，“ sample1”表也会增加。

Answer 1

您需要使用PIVOT

由于您没有提及特定的DBMS，所以我们无法真正为您提供正确的答案。

但是，通过很少的研究，您会发现PIVOT的需求。
