Re: [sqlite] Most appropriate Web based database? (Newbie)
Hi Len, The question you are asking is "loaded". Stay with the ansi SQL statements that SQLite supports and you will be okay. If you need to use the SQLite extensions now, you will have to write a "translator" in future - not too difficult. For an experienced programmer (which you will be if the situation you describe ever comes to pass) the answer is "use SQLite - it is a no brainer" Good Luck!

Re: [sqlite] Re: Select with left outer join - Am I going mad or just having a bad day?
Hi Ian, This one has been interesting! I'm trying to repeat the problem with several different databases - so far no luck. I use SQLite 2.8xx (project is already ongoing) and will test when I have time. I will post results if I find anything of value.

Re: [sqlite] Storing text in sqlite vs. external flat file
Hi Ken I found that performance began to fail miserably as the blob size increased above 500 bytes (has anyone else experienced this problem?). When I posted the problem, I think that someone stated the docs show the reasonable limit on blobs is 230 bytes. Anyways, I had to store the blobs direct to disk and use SQLite to track the addresses (no different than Oracle, MSSQL, MySQL etc). Please notify if you can get your system to work!

Re: [sqlite] ANN: SQLiteDB, a COM wrapper around sqlite has been released
HI George, I have tested the SQLiteDB for Visual Basic. I find it to be excellent - it has raised the standard for VB wrappers exponentially. I will be changing over all our new applications to this product - please keep it standardized as I will be posting references to it all over the 'Net. Again, thanks for developing an excellent product!

[sqlite] Saving BLOBs in Sqlite
Dear sirs,
I am trying to develop techniques to save BLOBs in Sqlite. What is the best
way to save jpg(S), bmp(s), etc?
Would it be best to use GetBitmapBits ("gdi32" library) and then save to
Sqlite as a byte array or is there a more efficient method?
I am new to Sqlite but it seems to be an amazing tool!
I look forward to any help and I thank you in advance for your input.
Sincerely,
Ed Porter
