我有一个扩展名为.sql的文本文件，其中包含用于将表和填充值构建为列的代码。
如何从中生成一个.db sqlite文件
答案 0 :(得分：0)
假设您通过命令使用SQLITE，请使用.read FILENAME运行SQL，然后使用.save FILENAME命令保存数据库（包括.db扩展名），或者在使用。阅读命令，您可以使用.open FILENAME）
例如将文件C：/User/Mike/mysql.sql用作：-
CREATE TABLE IF NOT EXISTS mytable (id INTEGER PRIMARY KEY, mydata TEXT);
INSERT INTO mytable (mydata) VALUES('Fred'),('Mary'),('Sue'),('Tom');
SELECT * FROM mytable;
启动命令窗口，然后：-
