Useful for debugging. Prints out a human-readable table of a database result.
Example (sorta):
pawn Код:
new DBResult:result = db_query(db, "SELECT * FROM blabla");
db_print_result(result);
db_free_result(result);
Beware that NULL values will cause it to crash,
that's not my fault.
Example output:
As you can see some content is cut-off, it's because of the field length limit (which you can easily modify).

Those are plain integer variables! Should be iWeapon and iAmmo.
