Re: [sqlite] SQLite and Windows 95

Hi, Thanks to you to help me with this problem. As I do not require special features (only insert/select/order by/delete), I think it is maybe easier to use an old version of SQLite. I will try with 3.6.10 as said by Max. If it does not work I will try an older one. Regards, Joel

[sqlite] FTS3 + SQLITE_OMIT_PAGER_PRAGMAS causes division by zero exception

Recent changes to FTS3 apparently require that SQLite must be compiled with pager pragmas, otherwise FTS3 will cause a division by zero exception as I have experienced right now. This means that the FTS3 extension can crash an application if the core SQLite library is compiled with

and what about using a DCOM like technology to open a distant database? the sqlite API will stay the same but behind the scene, it will access your server using a DCOM like technology? ___ sqlite-users mailing list sqlite-users@sqlite.org

[sqlite] how to realize rollback or commit using sqlite?

Hi, erveryone I'm a beginner. I think sqlite can automatically do commit or rollback when sql statments(insert,update,or delete) are finished. Is it correct? Or it must use "Begin transation"? Anybody can give me some examples? Thanks.

Re: [sqlite] SQLite server

Why not doing it with DCOM or Corba or what ever even the sockets? but hidden behind the same API of SQLite. The "real" sqlite lib will be on the server. is it called "remote procedure call"? ___ sqlite-users mailing list sqlite-users@sqlite.org

Re: [sqlite] SQLite server

This is where I think the problems will crop up. Can you imagine making a network round trip for each row fetch, and then for each column fetch of each row (sqlite3_column_type, sqlite3_column_double, etc). To avoid that, you would need to fetch a lot (buffer) of data and bring it back to the

Re: [sqlite] 64 bit sqlite 3

At first I was like "awe, I don't wanna do my homework". I'd have to recompile all my little utilities and distribute them rather than just distribute a new DLL and it would be nice to keep our local program maintainers from "helping" instead of keeping to the officially released code.

Re: [sqlite] SQLite server

I think you can hide those details, you can perfectly retrieve all rows (or bunch of rows) and then do not make any network access, but still simulate the sqlite API. I would keep the connection open, it doesn't block other clients to connect as well, just the server has to be multi-process. the
