But the Background as i look at this feature is, i have allways and in every Table a First-Field named "RecID", Autoincremental, Primary Key, not editable. Also I ever have a RowID and never got this problem. But this i even my way... and now I understand the problem that have a public tool. > I wish there was a function like > long long int sqlite3_column_rowid(sqlite3_stmt*, int iCol); Yep. That's it.

Re: [sqlite] Charset-Confusions
I am writing as the author of SQLiteSpy: SQLiteSpy does not currently does not allow editing field values in the display grid. However, this is planned for a future version. You have asked "How is it so complicated? *hmmm*" Well, because SQLite does not have an interface to save values back to the database for any arbitrary select statement. In order to update a cell, its database, table, column, and row must be determined, which is unfortunately not always possible, for example if the query does not contain the RowID as part of its result set. Then SQLiteSpy would have to modify the query, and so on. I wish there was a function like long long int sqlite3_column_rowid(sqlite3_stmt*, int iCol); which returns the RowID for the field. This could then be used to build reliable update statements (see my other post to this list).

Thanks for your answer. I found SQLiteSpy in Web and first time it seems to works very well. But I cannot edit Cells in Grid. And the Edit-Area below is editable, but dont save the changes to cell. I dont found some references how to do. Indeed, thats curious. No one of the found Admintools can edit a Cell-Value directly in the Cell. I think, edit directly in Cell and dont ask "Do you want to save the changes?" is simplest way to do this. Most time, i know exactly, what I want to edit and save. How is it so complicated? *hmmm* Best regards, Anne -- GMX Produkte empfehlen und ganz einfach Geld verdienen! Satte Provisionen für GMX Partner: http://www.gmx.net/de/go/partner

Anne, You should try Ralf Junker's SQLiteSpy (see http://www.zeitungsjunge.de/delphi/sqlitespy/index.htm). I use it, and it works very well. The current version doesn't allow editing the field values in the display grid, but I think he has said that he is working on that feature. HTH Dennis Cote
RE: [sqlite] Charset-Confusions
I can't comment on Anne's situation, but I too think there is something funny going on with charsets because of one small data point: I open and use a database using the '16' APIs (ie sqlite3_open16, sqlite3_prepare16, etc). When I tried to run an EXPLAIN QUERY PLAN statement (like "EXPLAIN QUERY PLAN SELECT id FROM LIST WHERE test=1" just as an example) using my typical prepare16, step16, etc code, I'd always get back an empty result. However, if I run the identical statement with sqlite3_exec (NOT the 16 version) the results came back as expected. After figuring this out I just worked around the problem, but it makes me think there might be something there. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, May 15, 2006 1:45 PM To: sqlite-users@sqlite.org Subject: [sqlite] Charset-Confusions Hi I have some confusion again.
