Question

我想选择在特定uuid之后开始的所有行，例如这里是数据

+--------------------------------------+-----------+------------+
|                 uuid                 | divisi_id | divisionid |
+--------------------------------------+-----------+------------+
| b303a96b-2a03-4b5e-90a1-6b3631fc82af | BTT       |          3 |
| 8c4bf1b8-7477-42e4-affb-31bafa8648f1 | BTT       |          3 |
| 6639909d-74e1-4dec-a1f3-f70703c0b6c6 | BTT       |          3 |
| 1a1aa367-1467-4811-848d-694dbe98a5a8 | BTT       |          3 |
| e739b352-d952-4ec8-980e-a50180e18144 | BTT       |          3 |
+--------------------------------------+-----------+------------+

现在，例如我有uuid = 8c4bf1b8-7477-42e4-affb-31bafa8648f1（第2个条目）。如何在那个uuid之后选择行？我根本不知道。

试试这个

SELECT d1.* FROM
(SELECT Row_Number() over (order by id) AS RowIndex, * from tableName ) AS d1 
INNER JOIN 
(SELECT Row_Number() over (order by id) AS RowIndex, * from tableName) AS d2 
ON (d2.uuid  = '8c4bf1b8-7477-42e4-affb-31bafa8648f1' and d1.RowIndex > d2.RowIndex)

希望你有主键!!

如果您没有主键而不是

SELECT d1.* FROM
(SELECT Row_Number() over (order by (select null)) AS RowIndex, * from tableName) AS d1 
INNER JOIN 
(SELECT Row_Number() over (order by (select null)) AS RowIndex, * from tableName) AS d2 
ON (d2.uuid  = '8c4bf1b8-7477-42e4-affb-31bafa8648f1' and d1.RowIndex > d2.RowIndex)

在postgresql中选择特定uuid之后的所有行
