如何过滤 RETURNING *？

Question

我有以下场景。我有一个 table，它有一个 IsDeleted 标志，我设置它用于记录 'soft delete'。我正在做一个 UPSERT，我在其中添加、修改和标记为删除了一些记录。我想从 RETURNING 语句中排除已标记为已删除的记录。我试图将 WHERE tbltest_IsDeleted = 0 附加到以下 SQL 的末尾，但它给了我错误： ERROR: syntax error at or near "WHERE"

如何过滤以下语句中RETURNING *的结果？

INSERT INTO tbltest (
    tbltest_ID,
    tbltest_Name,
    tbltest_Description,
    tbltest_IsDeleted) 
VALUES 
(DEFAULT, 'new record','new record description', 0),
(4, 'modified record name','modified record description', 0),
(5, 'existing record name','existing record description', 1)
ON CONFLICT (tbltest_ID) DO UPDATE SET (
    tbltest_Name,
    tbltest_Description,
    tbltest_IsDeleted) = (
    excluded.tbltest_Name,
    excluded.tbltest_Description,
    excluded.tbltest_IsDeleted) RETURNING *;

解决了，这是我能够做到的：

WITH rows AS (
    INSERT INTO tbltest (
            tbltest_ID,
            tbltest_Name,
            tbltest_Description,
            tbltest_IsDeleted) 
    VALUES 
    (DEFAULT, 'new record','new record description', 0),
    (4, 'modified record name','modified record description', 0),
    (5, 'existing record name','existing record description', 1)
    ON CONFLICT (tbltest_ID) DO UPDATE SET (
            tbltest_Name,
            tbltest_Description,
            tbltest_IsDeleted) = (
            excluded.tbltest_Name,
            excluded.tbltest_Description,
            excluded.tbltest_IsDeleted) RETURNING *
)
SELECT * FROM rows WHERE rows.tbltest_IsDeleted = 0

希望这可以节省一些时间 ;-)
