Re: [sqlite] SQLite- Memory heap usage query

Didn't you ask this question 4 days ago, and it was answered? The only difference in your question this time around seems to be that you are asking for a way to reduce the db file size. You could utilize a compression library on your data... check the mail archives and also google for that

Re: [sqlite] Visual Studio 2005 Linker Problems - SQLite v3.6.3

Hi Shane, Thanks very much for the suggestion. I excluded the 'rtree.c' source file from my build configuration and it now links fine (release and debug). I guess there's still an underlying issue but as I don't need the rtree module it doesn't affect me! Thanks again, Ian Shane Harrelson

Re: [sqlite] Visual Studio 2005 Linker Problems - SQLite v3.6.3

rtree support is an extension to SQLite and is not needed to use the core functionality. Try leaving the rtree source files out of your builds to see if this corrects your problem. You might also consider using the SQLITE_OMIT_LOAD_EXTENSION option as well. http://www.sqlite.org/compile.html

[sqlite] "analyze" command slow for large amounts of data; alternative possible?

The problem --- I'm using the "ANALYZE" command of SQLITE to try and improve performance for queries. However, I'm finding that the actual analyze call can take a long time to run for large amounts of rows (e.g. >2). This is especially the case if a lot of data has been changed

[sqlite] 100 million records will be fine?

Hi. I've started a SQLite C++ project that could peak at 100 million records (250 bytes per record spread over 20 fields) and would like to ask if anyone has seen SQLite projects of this magnitude. The Windows data logging project will add up to 1 million records per day and run queries
