In my testing.

public int executeUpdate(String sql)
throws SQLException

Insert, update, delete
If success return >0, If failure return 0
return value means row count

public int[] executeBatch()
throws SQLException

It return int[], the ints are all "-2".
return "-2" means what.

The gif is at java.sql.Statement -> Field Summary -> Constant Field Values , you will get it.
