如何在将结果插入到HSQLDB表中时对结果进行排序？

Question

当我使用HSQLDB运行以下脚本时，出现错误消息user lacks privilege or object not found: T2C1。如何将行插入表TABLE3？我可以在不添加其他表的情况下实现这一目

请注意，如果我对线条ORDER BY "T2C1", "T1C2"发表评论，我将不会收到任何错误消息，但TABLE3也不会被排序。

DROP TABLE "PUBLIC"."TABLE1" IF EXISTS; 

CREATE TABLE "PUBLIC"."TABLE1" (
    "C1" VARCHAR(10), 
    "C2" VARCHAR(10), 
    "C3" VARCHAR(10) 
); 

INSERT INTO "PUBLIC"."TABLE1" ("C1", "C2", "C3") VALUES ('a', 'b', 'c'); 
INSERT INTO "PUBLIC"."TABLE1" ("C1", "C2", "C3") VALUES ('d', 'e', 'f'); 

DROP TABLE "PUBLIC"."TABLE2" IF EXISTS; 

CREATE TABLE "PUBLIC"."TABLE2" (
    "C1" VARCHAR(10), 
    "C2" VARCHAR(10), 
); 

INSERT INTO "PUBLIC"."TABLE2" ("C1", "C2") VALUES ('a', 'b'); 
INSERT INTO "PUBLIC"."TABLE2" ("C1", "C2") VALUES ('u', 'v'); 

DROP TABLE "PUBLIC"."TABLE3" IF EXISTS; 

CREATE TABLE "PUBLIC"."TABLE3" (
    "C1" VARCHAR(10), 
    "C2" VARCHAR(10), 
); 

INSERT INTO "PUBLIC"."TABLE3" (
    "C1", 
    "C2" 
) 
SELECT 
(SELECT 
"T2"."C1" AS "T2C1" 
FROM "PUBLIC"."TABLE2" "T2" 
WHERE "T2"."C1" = "T1"."C1"), 
"T1"."C2" AS "T1C2" 
FROM "PUBLIC"."TABLE1" "T1" 
ORDER BY "T2C1", "T1C2" 
; 

* *DSV_COL_DELIM=, 
* *DSV_ROW_DELIM=\n 
* *DSV_TARGET_FILE=results.csv 

\x "PUBLIC"."TABLE3" 

Answer 1

HSQLDB 2.2.x支持在这里使用ORDER BY。您的SELECT的问题是缺少标量子查询的列别名T2C1。试试这个：

INSERT INTO "PUBLIC"."TABLE3" (
    "C1", 
    "C2" 
) 
SELECT 
(SELECT 
"T2"."C1" AS "T2C1" 
FROM "PUBLIC"."TABLE2" "T2" 
WHERE "T2"."C1" = "T1"."C1") AS T2C1, 
"T1"."C2" AS "T1C2" 
FROM "PUBLIC"."TABLE1" "T1" 
ORDER BY "T2C1", "T1C2" 
;

它没有太大的意义对我来说，因为作为别人已经提到的各种论坛插入的顺序无关：

• http://www.dbforums.com/microsoft-sql-server/1617505-insert-into-order.html
• http://social.msdn.microsoft.com/Forums/en/transactsql/thread/aeb1053d-0dc2-4dc3-96f5-8b213fed9669

我认为HSQLDB只是给出了一个错误的错误信息。它不适用于MSSQL。
