Often there is large but not complete overlap between these two groups due to frame issues etc. You can add a limit to the solution I described and it will not give you more than that number of rows. Minimax sampling In imbalanced datasets, where the sampling ratio does not follow the population statistics, one can resample the dataset in a conservative manner called. The SAMPLE clause will give you a random sample percentage of all rows in a table. R example, here we obtain 25% of the rows: SELECT FROM emp.
