Hello, thank you for the great project.

I would like to use the uSQLite on the ESP32-S3 (8MB RAM, 32MB Flash), where the uSQLite database will have ~4MB. So to be faster the idea is to load all database to the RAM, and get (the selects) to the RAM database, and when need to write data (insert/update), write on disk database, syncing with the RAM database.

Is possible to copy entire database to the RAM and use uSQLite on RAM e when needed insert/update data, write that specific data to disc, like SQLite support?

Should be like this (https://stackoverflow.com/a/53253110):

import sqlite3

source = sqlite3.connect('existing_db.db')
dest = sqlite3.connect(':memory:')
source.backup(dest)

and/or this (https://stackoverflow.com/a/53253110):

# first connection
c1 = sqlite3.connect("file::memory:?cache=shared", uri=True)

# second connection, to the *same database*
c2 = sqlite3.connect("file::memory:?cache=shared", uri=True)

# third connection, to a different database altogether
c3 = sqlite3.connect('/tmp/sqlite3.db', uri=True)
# can attach to the shared in-memory database, but only if you used
# uri=True on the original connection
c3.execute("ATTACH DATABASE 'file::memory:?cache=shared' AS inmem")

Thank you in advance!

Good day

I get the following intermittent errors when running micropython (windows port, dev and standard variants) with the attached script.

usqlite_Error: database disk image is malformed
usqlite_Error: file is not a database

Sometimes it runs through successfully, but fails most of the time.

Sometimes it fails with null reference exceptions in different parts of sqlite3.c, so might be a loose pointer or buffer overflow?

I think there is a problem with the latest edits.. could you please check?

Hello! Im trying to build firmware for Lolin S2 Mini.
I put the sqlite directory into micropython/examples and include its cmake file into main cmake file in examples.

Using: make BOARD=LOLIN_S2_MINI and USER_C_MODULES with path to main micropython.cmake.
Get a lot of errors.

idf_py_stdout_output_20009.log
idf_py_stderr_output_20009.log

First, my apologies for the verbose post(complete build output in zip file). As you can see below the build fails for esp32. Any direction will be appreciated.
Thanks,
Rick

FYI, I can build esp32 successfully without usqlite.

Good day

If I run the attached script (see below), tested on windows, unix and stm32f769 builds, it runs fine until the free memory drops below 5%, and then crashes with the error:

Traceback (most recent call last):
File "E:\scratch\micropython\mp_usqlite\samples\producer_consumer_sd.py", line 167, in
File "asyncio/core.py", line 1, in run

usqlite_Error: error (26): file is not a database sql: 'SELECT COUNT(ID) from items;'
PS E:\scratch\micropython\mp_usqlite\micropython\ports\windows\build-dev>

If I run the script with useSqlite = False, the memory usage drops until about 1%, but the the gc kicks in and continues as expected.

Although, if useSqlite = True, when the memory usage drops to around 5%, the above error is displayed.
Might it be an issue in the interop between the gc and usqlite?

Hello!

I'm playing with an idea to use sqlite on microcontroller (RPI PICO). I've successfully built the firmware with usqlite module (with micropython v1.22.1)

When I execute the example script multiple times (from your README):

import usqlite

if not usqlite.mem_status():
    usqlite.mem_status(True) # Enable memory usage monitoring

con = usqlite.connect("data.db")

con.executemany(
    "BEGIN TRANSACTION;"
    "CREATE TABLE IF NOT EXISTS data (name TEXT, year INT);"+
    "INSERT INTO data VALUES ('Larry', 1902);"+
    "INSERT INTO data VALUES ('Curly', 1903);"+
    "INSERT INTO data VALUES ('Moe', 1897);"+
    "INSERT INTO data VALUES ('Shemp', 1895);"+
    "COMMIT;")

with con.execute("SELECT * from data") as cur:
    for row in cur:
        print("stooge:", row)
        
con.close()

print("usqlite mem - current:", usqlite.mem_current(), "peak:", usqlite.mem_peak())

the device freezes. I tried to disable the mem_status feature. I'm not sure how to debug this, but I noticed strange issue (at least for me). If I upload the generated uf2 using picotool, then connect to sqlite db from repl, disconnect, and then when I verify the uf2 with the device flash (using picotool verify) it shows that the images are not the same (ERROR: The device contents did not match the file).

What could be the cause? What information do you need from me? Thanks a lot.

Good day

Are there any plans to make usqlite compatible with micropython 1.21? I get a compile error in usqlite_cursor.c in function:

STATIC mp_obj_t row_tuple(usqlite_cursor_t *cursor) {
int columns = sqlite3_data_count(cursor->stmt);

mp_obj_tuple_t *o = m_new_obj_var(mp_obj_tuple_t, mp_obj_t, columns);
o->base.type = &mp_type_tuple;
o->len = columns;

for (int i = 0; i < columns; i++)
{
    o->items[i] = usqlite_column_value(cursor->stmt, i);
}

return MP_OBJ_FROM_PTR(o);

}

syntax error: ')' in line:
mp_obj_tuple_t *o = m_new_obj_var(mp_obj_tuple_t, mp_obj_t, columns);

Micropython supports native code in mpy files. This means that, theoretically, you could build this project in such a way that you do not need to build and use a new micropython firmware image... You would just download a pre-built usqlite.mpy file for your microcontroller architecture, copy it over, and away you go.

This would be a super useful option, especially for those who are hesitant to try building their own firmware.

Un grand merci !!! for this package ...
We introduce python, tcp, sql but also recurcivité, graph, conquer and divide, dynamic programmic for the new curriculum of informatic for the grade 11 and 12
So, use ESP32 with micropython and sqlite, it's amazing for us !!!!

Three day after, i just goal to compil a firmware with micropython and usqlite ....

The big purpose is :

• use gcc8 and not gcc9
• python 3.8 and not python 3.10
• micropython 1.18 and not mycropython 1.19
  Some changes in new upgrade make impossible the compilation of usqlite

More information (in french) on my website : https://chinginfo.fr/dossier-esp32/?p=c

A big thank you for the porting of sqlite to micropython which will make the field of possibilities immense in our teaching

The following SQL

CREATE TABLE IF NOT EXISTS login(
  key TEXT NOT NULL PRIMARY KEY,
  name TEXT
);

Gives the error:

usqlite_Error: malformed database schema (sqlite_autoindex_login_1) - orphan index

Same happens if I try to set a column as UNIQUE.

I am using ESP32-S3 and ESP-IDF4.4.2, but there was an error during compilation:
#define TYPE_HAS_ITERNEXT(type) (type->flags & (MP_TYPE_FLAG_ITER_IS_ITERNEXT | MP_TYPE_FLAG_ITER_IS_CUSTOM | MP_TYPE_FLAG_ITER_IS_STREAM))
I think it should be caused by an incompatible version of MicroPython. May I ask which version of MicroPython you are using?

Or, how should I modify it for version 1.19?

Good day

I am following the getting started section on https://github.com/spatialdude/usqlite

I get the following error when following the instructions on https://github.com/spatialdude/usqlite/wiki/unix

sqlite/usqlite_module.c:127:35: error: ‘mp_obj_type_t’ {aka ‘const struct _mp_obj_type_t’} has no member named ‘make_new’

Hello, I started compiling firmware again for ESP32 (generic, c3, s3) ... I tried again to include your usqlite module and I get the following errors (see attached file)

I saw that in your "micropython.cmake", you had put a conditional for compilation under ESP32 ... I took the liberty of "short-circuiting" the conditional to make sure the command would run with all my compilations, but it didn't change anything

I'll have some time in March and April to try things out if you like ... Unfortunately my knowledge of C and Python is too limited (as well as esp-idf) to hope to solve this problem myself.

I compile my files with the latest specifications for micropython :
ESP-IDF: 5.0
Micropython : 1.22
(and python 3.10)

Sincerely

Hello, I just try the new version of uSqlite for micropython 1.196 ... No problems with the ports "unix" but it fails with the port "ESP32" ...

/sauvExt/esp32-1.19-4.4/modules/usqlite/sqlite3.c: In function 'sqlite3RunParser':
/sauvExt/esp32-1.19-4.4/modules/usqlite/sqlite3.c:171920:61: error: 'startedWithOom' undeclared (first use in this function); did you mean 'searchWith'?
     assert( db->mallocFailed==0 || pParse->rc!=SQLITE_OK || startedWithOom );

It's seems to be a problem of NDEBUG et SQLITE_DEBUG but i'm not able to correct it ...
Thanks for your work
Thomas
