I'm a little uncomfortable with getters that create an object every time they're read.

Suggested change

	{"memused", SQLITE_STMTSTATUS_MEMUSED},
	{"memUsed", SQLITE_STMTSTATUS_MEMUSED},

Since SQLite does not use an underscore here, I think memused is a more faithful name to the SQLite API.

[geeksilva97]

yeah, that was the pattern followed

Please @nodejs/sqlite , share your thoughts

Another method to reset stats would be nice to have

[araujogui]

SQLITE_STMTSTATUS_FILTER_MISS and SQLITE_STMTSTATUS_FILTER_HIT was introduced in SQLite 3.38.0.

3.37.2: https://github.com/sqlite/sqlite/blob/version-3.37.2/src/sqlite.h.in
3.38.0: https://github.com/sqlite/sqlite/blob/version-3.38.0/src/sqlite.h.in

[araujogui]

So maybe we need to enforce a minimum SQLite version on --shared-sqlite

Another method to reset stats would be nice to have

[araujogui]

Suggested change

	using db = new DatabaseSync(nextDb());
	using db = new DatabaseSync(':memory:');

[araujogui]

nit: This is structurally identical to GetLimitInfoFromName just above, we can replace both with a single function template.

template <typename T, size_t N>
static constexpr const T* FindByJsName(const std::array<T, N>& mapping,
                                       std::string_view name) {
  for (const auto& info : mapping) {
    if (name == info.js_name) {
      return &info;
    }
  }
  return nullptr;
}
