Question

-drop table r.stray_cust; 

CREATE VOLATILE TABLE r.stray_cust 
(
CustomerID INTEGER 
) 
PRIMARY INDEX (CustomerID); 

INSERT INTO r.stray_cust 
SELECT DISTINCT c.customerid AS customerid 
FROM customer c 
WHERE c.customerid 
NOT IN (
SELECT a.customerid 
FROM address a); 

ON COMMIT PRESERVE ROWS; 

select * from r.stray_cust;

好歷史記錄，你檢查的歷史細節？

ON COMMIT是CREATE TABLE揮發的一部分，所以您的查詢應該是：

CREATE VOLATILE TABLE r.stray_cust (CustomerID INTEGER) PRIMARY INDEX (CustomerID) 
ON COMMIT PRESERVE ROWS; 

INSERT INTO r.stray_cust 
SELECT DISTINCT c.customerid AS customerid 
FROM customer c 
WHERE c.customerid NOT IN (SELECT a.customerid FROM address a); 

或單步：

CREATE VOLATILE TABLE r.stray_cust AS 
(
    SELECT DISTINCT c.customerid AS customerid 
    FROM customer c 
    WHERE c.customerid NOT IN (SELECT a.customerid FROM address a) 
) 
PRIMARY INDEX (CustomerID) 
ON COMMIT PRESERVE ROWS; 

INSERT INTO r.stray_cust ;
