It works fine for me - What
The process, working in iOS:
* Retrieve an employee photo using web service call, encoded in Base64
string
* Convert Base64 string to NSData object - 3245 bytes
* Store NSData object to a Blob in SQLite - 3245 bytes
* Retrieve Blob to NSData object - 3245
Whoaa!! This is amazing!

One use of this I would like is to create a security framework around
arbitrary SQL queries from the user. So, for example, I'd love to
determine which tables (and which columns of those tables) a particular
query is going to access, and then compare that list against a whitelist of
columns the

I'm putting together a quick proof-of-concept application to explore the use of
System.Data.SQLite for applications running on Windows Mobile 6.1 using .NET
Compact Framework 3.5.
As long as I put the data access logic in the application, and make sure that

Works when I try it. Is there a stray non-printing character
Is this something crazy to ask as a developer ?
I think that even for the author something like this would make several tasks
easier.
Ideally I would like to feed the parser with an sql string, get it's syntax
tree, maybe do some rewrite and feed it execute it, this possibility can open

It seems that we already have something done, after your suggestion I looked
at the sqlite3 sources and found this function:
#ifndef NDEBUG

Thank you for your reply !
I understand your point.
But without remove your freedom could we have somehow an optional callback
that could be registered to receive what the parser found ?
It's a shame that we can not reuse the parser power !

This will output the steps the parser does (reduce, shift, fallback,...) but
not the syntax tree.

In the amalgamation source code you will find

Thank you for your reply !
The problem with "If you would like to write something that turns the output
of that parser into a syntax tree in your preferred format, go ahead. Should
be interesting." is that it's duplicated work that can/will go out of sync
with sqlite repository.
For the
Why do I get a syntax error from this SQL?
SELECT * FROM SnappedFrames WHERE EXISTS (SELECT 1 FROM FilmSizeOverrides);
SQLite says the error is near SELECT, but doesn't say which SELECT. If
I say either
SELECT * FROM SnappedFrames WHERE 1;
or
SELECT 1 FROM FilmSizeOverrides;
then there's
On the right panel there is a live syntax tree of the sql on the left panel,
we can edit the sql on the left panel and the syntax tree on the right panel
is updated.
The idea is to have a way to get a syntax tree of a sql string through the
sqlite parser: synatx_tree

The vast majority of copies of SQLite don't run on normal computers, they're
embedded
Hello Richard !
Can we have a sqlite function that given a sql string return something like
this https://codeschool.github.io/sqlite-parser/demo/ =>
Syntax Tree ?
syntax_tree sqlite3_sql_syntax_tree(const char *zSql);
Possible return types for sqlite3_sql_syntax_tree:
- json

That function implements PRAGMA parser_trace.

No.
That would make the abstract syntax tree an interface, which means
that we
How to detect beginning and end of output from a SQL Statement piped to a
subprocess:
Initialize the subprocess with
.header off
.separator
.mode list
And then delimit your queries
- SELECT ' START';
-
- SELECT ' END';
Discarding everything not between the expected START and END lines
What are we supposed to be seeing there?
