generate_series

generate_series(START, STOP) - Returns a table with the single ‘generate_series’ column (UInt64) that contains integers from start to stop inclusively.

generate_series(START, STOP, STEP) - Returns a table with the single ‘generate_series’ column (UInt64) that contains integers from start to stop inclusively with spacing between values given by STEP.

The following queries return tables with the same content but different column names:

SELECT * FROM numbers(10, 5);
SELECT * FROM generate_series(10, 14);

And the following queries return tables with the same content but different column names (but the second option is more efficient):

SELECT * FROM numbers(10, 11) WHERE number % 3 == (10 % 3);
SELECT * FROM generate_series(10, 20, 3) ;
