sql - 如何在HSQLDB中使用多行SELECT语句导出数据？

Question

当我在 HSQLDB 2.2.5 中使用命令“java -jar sqltool.jar --rcFile sqltool.rc db_file q.sql”运行以下脚本时，我收到错误消息:“用户缺少权限或找不到对象: 选择”。如果我将 \x 命令设为单行语句，HSQLDB 将成功执行脚本。我想将我的 \x 分成多行以提高可读性。如何在 HSQLDB 脚本中使用多行 \x 命令？

--q.sql
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');

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

\x SELECT
( SELECT TOP 1 "T2"."C1" FROM "PUBLIC"."TABLE2" "T2" WHERE "T2"."C1" = "T1"."C1") AS "T2C1",
"T1"."C2" AS "T1C2"
FROM "PUBLIC"."TABLE1" "T1"
ORDER BY "T2C1", "T1C2"

更新:根据@Blaine 的建议，我切换到 HSQLDB 2.2.6 并将上述脚本中的 \x 命令替换为以下内容:

\.

SELECT
(SELECT TOP 1 "T2"."C1" FROM "PUBLIC"."TABLE2" "T2"
 WHERE "T2"."C1" = "T1"."C1") AS "T2C1",
"T1"."C2" AS "T1C2"
FROM "PUBLIC"."TABLE1" "T1"
ORDER BY "T2C1", "T1C2"

.;

这需要版本 2.2.6。

一旦您拥有 2.2.6，\x? 将向您展示您需要知道的一切。

由于您希望它在脚本中运行，您可以使用原始模式将多行 SQL 语句输入到 SqlTool 的命令缓冲区中，然后使用 \x :。助记符:“:”表示SqlTool的编辑缓冲区。
