When we try to create a view within a funcion we get ERROR: there is no parameter $1. This is the sample code.
Begin
CREATE VIEW artikelnr AS
SELECT datum, 'uitgifte' as "type", CASE WHEN 'test'='test' THEN 0 END as "aantal ontvangen", aantal as "aantal uitgegeven"
FROM uitgifteregel
JOIN artikel ON artikel.artikelnr = new.artikelnr
JOIN uitgifte ON uitgifte.uitgiftenr = uitgifteregel.uitgiftenr
UNION
SELECT datum, 'ontvangst' as "type", aantal as "aantal ontvangen" , CASE WHEN 'test'='test' THEN 0 END as "aantal uitgegeven"
FROM ontvangstregel
JOIN artikel ON artikel.artikelnr = new.artikelnr
JOIN ontvangst ON ontvangst.ontvangstnr = ontvangstregel.ontvangstnr;
Return new;
end;
When we replace new.artikelnr on line 7 with value 1 it works like it should, but the function needs to work with different artikelnr's.
example line 7: JOIN artikel ON artikel.artikelnr = new.artikelnr
Please point us in the right direction.
