-SQLite* db = sqlite_connect("/tmp/app.sqlite");

-StringMap params;

 Result rows are objects keyed by column name. SQLite integer, float, text, blob, and null values are converted to DValue values. Blob values are returned as byte strings.
 
 For statements that do not return rows, inspect `sqlite_affected_rows()` or `sqlite_insert_id()` after the call.
