SORM
Description
SORM stands for SQL ORM. I made this because I have a love/hate relationship with both. I combined them together to have the best of both worlds!
The naming of my functions and variables are something to get used to. They are all abbreviations, kinda like C stdlib style. It looks weird, but you get used to it quickly and in reality, you just use a few of them.
Examples of common used functions are:
sormc(char *path)connect to database. Returnsint.sormq(int conn, char *sql, ...)execute query. Variadic arguments. Works likeprintf. Returns result in CSV format in case ofSELECT.sorm_csvd(char *csv_data)dumps your CSV result data to a nice fixed content width table in the terminal.
Thread safety
I wonder if I have configured sqlite3 the right way for thread safety. It maybe requires a manual compilation of the shared object file. Will look into that. SORM is written with thread safety in mind.
Design choices
I use mainly native types and not custom structs. For example, the db parameter is an int. This is so it can easily communicate with other languages using a shared object file.
Same argument is for the result set of sormq (the query function) resulting in a char * containing CSV data.
While the performance is nice, it's not written with performance in mind at all.
Python support
The Python library is low quality. I made it just for fun and test. This is not a defitive version. But it show very well how to communicate with a shared object file. I'm sure someone will be happy with examples how to use variadic functions trough Python to C. See sorm.py
C API examples:
Connecting
int db = sormc("db.sqlite3");
Create table
This one should return true if executed.
sormq(db, "CREATE TABLE IF NOT EXISTS pony (id INTEGER PRIMARY KEY AUTOINCREMENT,name,age);",NULL);
Inserting
sorm_pk iid = sormq(db, "INSERT INTO pony (id, name, age) VALUES (NULL, %s, %d);",
"Retoorded retoor",
42
);
Using ? is also possible for arguments like this (comfy for Python usage):
sorm_pk iid = sormq(db, "INSERT INTO pony (id, name, age) VALUES (NULL, ?s, ?d);",
"Retoorded retoor",
42
);
Selecting
IN query
sorm_str csv = sormq(db, "SELECT * FROM pony WHERE id in (?d,?d,?d)",1,2,3);
free(sorm_str);
LIKE query
sorm_str csv2 = sormq(db, "SELECT * FROM pony WHERE id > %d and age = %d AND name LIKE ?s", 1, 34, "%toor%"));
free(sorm_str);
Yes, you did see that right, you can use the default native free!
Disconnecting
sormd(db);
