SqLite Client/Server Library

Post by birosys »

From the http://planetsquires.com/
"SQLite Client/Server a great multi-connection, multi-threaded server application that allows the SQLite3 database system to handle multiple SQL requests from different users over a network or internet. Source code is freely available."

I translate headers for freebasic.

Cool. Thanks for translating the code to FB. I have BLOB support added for the next version. I am in the process of adding support to run the server as a Window Service. Once that is done then the next version will be uploaded.

SQLite3 is an awesome database that is so small and easy to use with no installation or configuration requirements. The client/server is my attempt to use the database in a multiuser scenario in a easy way. It is still a very young project but it does work well based on my testing.

Hi PaulSquires

Thank you for your response, and thank you for great software.
SqLite Server is very promising project.
Simple, Small and Clean code.
I hope so that FB community will accept this great project very well.

Sorry for my poor english, and thank you again.

I find it pretty useless.
Sqlite is great for projects that need a small, embedded database. If I were to write a program that should connect to a database server, I would currently most certainly use a more advanced database system specifically designed for that purpose.

If you'd written a single user app with SQLite as a backend, it'd be a nice quick way to make it multi-user.

I remember seeing this a while back, but thought it was a commercial offering just available for PowerBASIC.

Useless is a bit harsh. Sure, lots of people use SQLite as a standalone, embedded database, but many more quickly find that they want to extend their SQLite based applications to multiuser. The client/server set up is the best way to do this and my project is just a simple way to do it. If your project involves heavy database accesses or needs more advanced server features then I agree wholeheartedly with you - a more robust solution should be used. :-)

Indeed, I was a bit harsh, sorry, didn't pay to much attention to the multiuser part

dani.user: So, from your experience of writing client/server database apps, which one would you recommend?

Paul: Many thanks for creating/making this available (and, of course, birosys for the translation :-) )

Re: SqLite Client/Server Library

Post by NormalUser »

I am unable to find the library "sql3client" in the below code to load.

hndl=DylibLoad("sql3client")
sqlite3Client=DylibSymbol(hndl,"SQLITE3CLIENT")


Can anybody help?

This is an older version of the SQLite Client/Server product. That product was replaced/updated with an entirely new code base called SQLitening. It is a much better code base and much more robust and functional. You can get the code from the dedicated SQLitening forums:

Thanks McLovin

I was wondering whether anybody translated the headers for freebasic of this new version.

Here is my first attempt at the SQLitening and FreeBasic interface:

If you use it and find that things need to be changed, etc then please let me know.

I looked at Paul's link to his forum and the RAR file containing the port to freebasic is no long there.

Does anyone have it?

I was able to find the RAR archive file on my backup hard drive to I re-uploaded it that post.
