使用多個 select 語句插入私有臨時表

Question

我有一個私有臨時表，我想將來自不同表的多個 select 語句的記錄插入表中。

CREATE PRIVATE TEMPORARY TABLE ora$ptt_my_temp_table (
  ID NUMBER,
  name VARCHAR(20),
  docType VARCHAR(20)
)

INSERT INTO ora$ptt_my_temp_table(ID, name, docType)
(SELECT ID FROM Case WHERE userCase = 'test'),
(SELECT userID FROM CASE where ID = '3'),
(SELECT title from Version WhERE ID = '3')

我以為會是這樣，但我缺少表達或有時值太多。 我不確定出了什么問題。 抱歉不習慣 Oracle SQL，已經使用 SQL 服務器一段時間了

您可以使用select. . . from dual select. . . from dual select. . . from dual ：

INSERT INTO ora$ptt_my_temp_table (ID, name, docType)
    SELECT (SELECT ID FROM Case WHERE userCase = 'test'),
           (SELECT userID FROM CASE where ID = '3'),
           (SELECT title from Version WhERE ID = '3')
    FROM dual;
