sqlite3中更快的批量插入？ [英] Faster bulk inserts in sqlite3?

问题描述

我有一个大约30000行数据的文件，我想加载到sqlite3数据库。有没有比为每行数据生成insert语句更快的方法？

数据是空格分隔的，并直接映射到sqlite3表。是否有任何类型的批量插入方法，用于向数据库添加卷数据？

有没有人设计了一些非常好的方法，如果不是内置？ >

我应该先问这个问题，是否有一个C ++方法来从API做呢？

解决方案

您还可以尝试调整一些参数，以获得额外的速度。具体来说，你可能想要 PRAGMA synchronous = OFF; 。

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?

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?

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

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

解决方案

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