我正在使用gStore 的命令行查询模式（gquery）。首先，我使用 创建了一个示例数据库bin/gbuild -db test_db -f test_db.nt，其中 test_db.nt 仅包含一行文本：<a> <b> <c>。然后我在 gStore 的根目录中创建了两个文件，用于更新和查询数据库，分别称为 test_insert.rq 和 test_query.rq。这些文件的内容如下：
测试插入.rq：
INSERT DATA {<a1> <b1> <c1> .}测试查询.rq：
SELECT * WHERE {?x <b1> <c1> .}
通过 启动命令行查询会话后bin/gquery -db test_db，我执行插入：
> sparql test_insert.rq
然后，在同一个会话中，我执行查询：
> sparql test_query.rq
This returns <a1> as the result for ?x, which is correct. However, if I exit the gquery process by Ctrl + C, restart it with the same command, and execute the query again, no results are returned.
Since the results are correct in the same session, I assume this is not an update bug. Are there any additional steps I should perform to ensure that the updates done in the command line mode of gquery are preserved after restarts?
