PostgreSQLFunction with two select statements
I'm trying to create a PostgreSQL function declaring two variables to return on each one the result of a different query, the query themselves are really simple, and rely on the same select with different conditions:
select count (*) from editions where year >= '2000'
and
select count (*) from editions where year < '2000'
The structure of the table is also simple, there are three rows:
- Code (numeric)
- Version (character)
- Year (integer)
How can I create this function?

This is so basic.. I think you can find many tutorial in Google to create this Function.. And your Year column are Integer so don't treat like String use Single Quote..
Function totalRecords1()
CREATE OR REPLACE FUNCTION totalRecords1()
RETURNS integer AS $total1$
declare
total1 integer;
BEGIN
SELECT count(*) into total1
FROM your_table
WHERE year >= 2000;
RETURN total1;
END;
$total1$ LANGUAGE plpgsql;
Function totalRecords2()
CREATE OR REPLACE FUNCTION totalRecords2()
RETURNS integer AS $total2$
declare
total2 integer;
BEGIN
SELECT count(*) into total2
FROM your_table
WHERE year < 2000;
RETURN total2;
END;
$total2$ LANGUAGE plpgsql;
And Select Statement
select totalrecords1(), totalrecords2();
