How to get all the points that the distance between them is less than (some distance) in spatialite

I am working with "SpatiaLite" and i have a table with a geometric column. this column is a BLOB with POINTS. for example to insert a point i do:

"INSERT INTO exampletable(geom) VALUES(GeomFromText('POINT(-101.1 46.6)', 4326))"

I want to get all points in this table that the distance between them is less than some distance (3000m for example).

I have in this table 1800 row with different points.

Thx
