sqlite3：随着表的删除而转储

我正在尝试使用

sqlite3

转储sqlite数据库：

sqlite3 example.sq3 .dump > backup.sql

这是一个示例输出：

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE IF NOT EXISTS "articles" (
"id" INTEGER PRIMARY KEY AUTOINCREMENT,
"author_id" INTEGER,
"title" VARCHAR,
"body" TEXT,
"published" VARCHAR(1) DEFAULT 'N'
);
INSERT INTO "articles" VALUES(1,1,'First Article','First Article Body','Y');
INSERT INTO "articles" VALUES(2,3,'Second Article','Second Article Body','Y');
INSERT INTO "articles" VALUES(3,1,'Third Article','Third Article Body','Y');
CREATE TABLE IF NOT EXISTS "comments" (
"id" INTEGER PRIMARY KEY AUTOINCREMENT,
"article_id" INTEGER NOT NULL,
"user_id" INTEGER NOT NULL,
"comment" TEXT,
"published" VARCHAR(1) DEFAULT 'N',
"created" DATETIME,
"updated" DATETIME
);
INSERT INTO "comments" VALUES(1,1,2,'First Comment for First Article','Y','2007-03-18 10:45:23','2007-03-18 10:47:31');
INSERT INTO "comments" VALUES(2,1,4,'Second Comment for First Article','Y','2007-03-18 10:47:23','2007-03-18 10:49:31');
INSERT INTO "comments" VALUES(3,1,1,'Third Comment for First Article','Y','2007-03-18 10:49:23','2007-03-18 10:51:31');
INSERT INTO "comments" VALUES(4,1,1,'Fourth Comment for First Article','N','2007-03-18 10:51:23','2007-03-18 10:53:31');
INSERT INTO "comments" VALUES(5,2,1,'First Comment for Second Article','Y','2007-03-18 10:53:23','2007-03-18 10:55:31');
INSERT INTO "comments" VALUES(6,2,2,'Second Comment for Second Article','Y','2007-03-18 10:55:23','2007-03-18 10:57:31');
DELETE FROM sqlite_sequence;
INSERT INTO "sqlite_sequence" VALUES('articles',3);
INSERT INTO "sqlite_sequence" VALUES('comments',6);
COMMIT;

我的问题是，对于表方案，转储始终使用语句

CREATE table IF NOT EXISTS

，而我希望删除现有表，因为导入转储时，我无法物理擦除具有相同现有表和记录的现有数据库

我检查了

sqlite3

命令选项，但没有发现任何有用的内容

怎么办？

在

sqlite3

命令行shell中没有这样的选项

您必须创建自己的转储工具，或者编写脚本来调整SQL输出
