I suppose it's possible Maestro is messing it up.
You just need to do an "update mytable set IsReplaced=0 where IsReplaced is

You can do that from the shell.
Hopefully that makes your ADO happy.

You need to surround your entire sqlite3 command with back tics.
TomaCampo=`sqlite3 /Users/.and RecordTy8pe='R';"`
That's how you execute a command in bourne shell.

Natural joins are generally considered to be evil. Too many columns in common
can be bad.
If you just spell it out it works as expected
sqlite> explain query plan select * from a left join b where a.id=1 and
b.id=a.id;
0|0|0|SEARCH TABLE a USING COVERING INDEX sqlite_autoindex_a_1 (id=?)
I tested 3.7.9 on both Windows and Linux.
Both gave just "31|" as the output instead of "31|0" as you show.
And changing the select 9 made no difference...still got the same "31|"
answer for both.
I'm compiling with default options.

Your test_case.sql didn't come thru.
Can you report it in-ilne with an email?

From:
Do like a lot of us do and forget the DLL and just put sqlite3.c/h into your
project.
Then you can build and forget about it and it will always work in your project
(barring any future 32/64 incompatibilities). And you don't have to worry about
who's testing what bitset as it's completely
You're seeing on of my pet peeves...error messages like "cannot open file" or
Microsoft's famous "cannot load dll". Some of us need to know WHY.
So, change all your "cannot open" lines in shell.c to this:
fprintf(stderr, "Error: cannot open \"%s\":%s\n", zFile, strerror(errno));
Then

I have read through the ext/fts3/fts3/exp
Because tokenizers expect the pointer to increment and you're apparently not
doing that.
It says "here's token 'hal'" and if you return the pointer to "h" it points to
the same place so it returns "hal" right back to youergo the loop.
I think you would have to maintain state and your
