好吧，您是否查看了历史记录以了解详细信息？

ON COMMIT是CREATE VOLATILE TABLE的一部分，因此您的查询应为：

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 );

或一步一步：

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;

插入r.stray_cust;
