Just modify the last line from:
$$ LANGUAGE plpgsql;
To
$total$ LANGUAGE plpgsql;
You can call your function by
Select testFunc();
Create function documentation
Question
I`ve got only one database which name is "testDB". In command line: 1)
psql testDB
2) create a function as easies as is possible:
CREATE or replace FUNCTION testFun()
RETURNS integer AS $total$
declare
total integer;
BEGIN
SELECT count(*) into total FROM "Run";
RETURN total;
END;
$$ LANGUAGE plpgsql;
I don`t know what it is for?: $$ LANGUAGE plpgsql; but it was in some example.
So I copied it to command line.
After all nothing happen.
user@LenovoUbuntu:~$ psql testDB
psql (9.1.11)
Type "help" for help.
testDB=> CREATE or replace FUNCTION testFun()
testDB-> RETURNS integer AS $total$
testDB$> declare
testDB$> total integer;
testDB$> BEGIN
testDB$> SELECT count(*) into total FROM "Run";
testDB$> RETURN total;
testDB$> END;
testDB$> $$ LANGUAGE plpgsql;
testDB$>
Pay attention on:
testDB=>
testDB->
testDB>
