In this post, I am sharing examples of the RANGE Data type of PostgreSQL.
Using RANGE data type, you can store different types of range data and can easily use range criteria for further filters.
PostgreSQL has different RANGE type like:
- int4range (Integer)
- int8range (Bigint)
- numrange (Numeric)
- tsrange (Timestamp without time zone)
- tstzrange (Timestamp with time zone)
- daterange (Date)
Below is an example of this:
Create a sample table with different types of RANGES:
CREATE TABLE tbl_SampleRange
Insert few sample records:
INSERT INTO tbl_SampleRange
(1,'[10,20)'::int4range,'[2015-06-06,2016-08-08)','[2014-06-08 12:12:45,2016-07-06 14:12:08)')
,(2,'[40,50)'::int4range,'[2013-07-07,2014-09-09)','[2015-05-05 11:08:40,2016-08-03 16:08:08)');
SELECT data which are between ranges:
SELECT *FROM tbl_SampleRange WHERE NumberRange @>15;
SELECT *FROM tbl_SampleRange WHERE DateOnlyRange @>'2014-08-08'::date;
SELECT *FROM tbl_SampleRange WHERE DateTimeRange @>'2015-06-06 12:08:40'::timestamp;
