I am new to here and please let me know if I didn't make the question clearly.
If I have a m rows in a table and I want to select n rows uniformly. In other words, the interval between first row and next row is m / n.
For example, if i have a 10 rows and I want to select 5 rows out of them, then the selected rows would be 1, 3, 5, 7, 9 because the interval is 10 / 5 = 2.
Does anyone can help?
