SQL（进行中的数据库）-如何透视（转置）表

我是SQL新手，我一直在进度数据库上使用SQL（我确信它使用SQL92）

电流输出：

所需输出：

进度（或者至少我的不支持

PIVOT

）

我有以下代码：

Select Account,

SUM(CASE WHEN AccMonth = '201703' THEN Amount END) AS "201703",
SUM(CASE WHEN AccMonth = '201702' THEN Amount END) AS "201702",
SUM(CASE WHEN AccMonth = '201701' THEN Amount END) AS "201701"


FROM

(
Select pub."GL_Table"."AccNum_Col" AS "Account", pub."GL_Table"."AccMnth_Col" AS "AccMonth", Sum(pub."GL_Table"."Amount_Col") AS "Amount"
FROM pub."GL_Table"
GROUP BY pub."GL_Table"."AccNum_Col", pub."GL_Table"."AccMnth_Col"
) AS tempTB


GROUP BY Account

你不想做聚合

试试这个：

select account,
    case when accmonth = 201701 then amount end as "201701",
    case when accmonth = 201702 then amount end as "201702",
    case when accmonth = 201703 then amount end as "201703"
from your_table;
