Even in today's world there are sysems (the ones i know for sure are
atmel's avr and microchip's pic, both microcontrollers with Harvard
architecture) for which the equality of dara and code pointers does not
stand.
By the way some PICs have a 12-14 or 24 bit wide program bus to complicate

I can't answer why, but I can tell you it's fraught with potential
error. Inventing syntax runs the risk of supporting undesirable
behavior.

Huh. An example of which is the "medium model" of the Intel 8086:
20-bit code pointers and 16-bit data pointers. A machine for which C

I thought that WITH could be used only for SELECT statements.

It especially is the wrong method in your scenario since you
Thanks Keith
That's what I'd tried with my first attempt but naturally it didn't work.
Why is it that SQLite does not support a FROM clause in an update statement?

Apologies all, I'm fast asleep, it should've read:
UPDATE target
SET resource = (
SELECT s.resource FROM source s
WHERE ( s.ID = ID AND s.resource IS NOT NULL )
);

Apologies if I'm asking an obvious question, but I've searched and
tried various options and have not been able to arrive at an UPDATE
statement in SQLite that does what I need.
I've two tables with a unique identifier that enables me to link them.
I'm wanting to update the values of a particular

Of course, if there was a FROM clause for UPDATE it would be as simple as:
UPDATE target
SET resource = source.resource
FROM source
WHERE source.id = target.id
AND source.resource IS NOT NULL;
This is semantically the same as:
SELECT ...
FROM target, source
WHERE source.id =

Hello !
When testing one application that uses sqlite3 with "-fsanitize=address" I
was getting an error:
==1310==ERROR: AddressSanitizer: heap-use-after-free on address
And after study the code I found that the problem is in the function
openDatabase in src/main.c , it only happens when
19 matches
