在 sqlite3 中更快的批量插入?

Faster bulk inserts in sqlite3?(在 sqlite3 中更快的批量插入?)

问题描述

我有一个包含大约 30000 行数据的文件，我想加载到 sqlite3 数据库中.有没有比为每行数据生成插入语句更快的方法?

I have a file of about 30000 lines of data that I want to load into a sqlite3 database. Is there a faster way than generating insert statements for each line of data?

数据以空格分隔并直接映射到 sqlite3 表.是否有任何类型的批量插入方法可以将卷数据添加到数据库中?

The data is space-delimited and maps directly to an sqlite3 table. Is there any sort of bulk insert method for adding volume data to a database?

如果不是内置的，有没有人设计了一些非常棒的方法来做到这一点?

Has anyone devised some deviously wonderful way of doing this if it's not built in?

我应该先问一下，是否有 C++ 方法可以从 API 中做到这一点?

I should preface this by asking, is there a C++ way to do it from the API?

推荐答案

你也可以尝试调整一些参数 以获得额外的速度.具体来说，您可能想要 PRAGMA synchronous = OFF;.

You can also try tweaking a few parameters to get extra speed out of it. Specifically you probably want PRAGMA synchronous = OFF;.
