Question

Basically I need a min-heap functionality with sqlite as my data storage.
Lets say I need a table with 2 columns.
1st is unique ids and
2nd is integer value.
I always need the the id with smallest integer value.

Any suggestions ??

Answer 1

You get that for free on indexed columns

  CREATE TABLE table(
     one INTEGER PRIMARY KEY,
     two INTEGER
  );
  CREATE INDEX table_two ON table(two);

  INSERT ...

  SELECT MIN(two) FROM table;
