从JDBC读取SQLite数据库时遇到以下错误:[SQLITE_NOTADB] File opened that is not a database file (file is encrypted or is not a database)
。到目前为止,我可以告诉这个数据库没有加密(见下面的标题),sqlite3能够执行相同的命令,没有任何错误或警告。
有任何解决此问题的建议/想法吗?
源代码
package foo;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class Test {
public static void main(String[] args) throws ClassNotFoundException, SQLException {
Connection connection = null;
Statement statement = null;
String fn = "/Users/jerome/db.sql";
Class.forName("org.sqlite.JDBC");
connection = DriverManager.getConnection("jdbc:sqlite:" + fn);
statement = connection.createStatement();
statement.executeQuery("SELECT 1 FROM sqlite_master");
}
}
如何投放
java -cp /Users/jerome/.m2/repository/org/xerial/sqlite-jdbc/3.7.2/sqlite-jdbc-3.7.2.jar:foo.jar foo.Test
堆栈跟踪
Exception in thread "main" java.sql.SQLException: [SQLITE_NOTADB] File opened that is not a database file (file is encrypted or is not a database)

使用sqlite3
sqlite3 ~/Desktop/db.sql "SELECT 1 FROM sqlite_master"
1

[...]

数据库标题
hexdump -C ~/Desktop/db.sql | head

3.7.2似乎存在兼容性问题。当我切换到3.7.15-M1时问题消失了。我不确定为什么。

我今天遇到了同样的问题,原因是我用旧的打开了新的SQLite数据库(sqlite-jdbc版本:3.21.0.1) “ SQLite管理员(版本:0.8.3.2公开测试版),年份:2013”。 所有SQL语句都没有任何问题,但保存后,无法再连接到数据库(通过JDBC)。
因此我将DB Programm更改为“ SQL浏览器for SQLite 3.9.1 ,2017年”,所有内容再次运行!
这需要花费时间和精力,因为我没有考虑过......但也许我可以帮助别人用我的解决方案节省一些时间: - )
