amazon-redshiftHow do I generate a series in Amazon Redshift?
Generating a series in Amazon Redshift is done using the generate_series
function. This function allows you to generate a series of values based on a start and end value, as well as an interval.
For example, this code will generate a series of numbers between 1 and 10, with an interval of 2:
SELECT *
FROM generate_series(1, 10, 2);
The output of this code will be:
1
3
5
7
9
The syntax of the generate_series
function is as follows:
generate_series(start, end, interval)
start
: The start of the seriesend
: The end of the seriesinterval
: The interval between each number in the series
You can also generate a series of dates using the generate_series
function. For example, this code will generate a series of dates between two dates, with an interval of one day:
SELECT *
FROM generate_series('2020-01-01', '2020-01-10', '1 day');
The output of this code will be:
2020-01-01
2020-01-02
2020-01-03
2020-01-04
2020-01-05
2020-01-06
