Problem with query

[Barbara Woolums <barb.woolums@xxxxxxxxx>]

Hi there,

Could someone please tell me why the following query won't work

select DISTINCT get_unit(unit) as unit, get_ingredient(ing) as ing, get_ing_aisle(1,ing) as aisle
from recipe_ing where recipe in(1084, 1086, 1012, 618) and qtydec>0 and ing not in(select ing from excluded_ing where owner=1)
order by aisle

the query returns the following with no values for aisle, but there should be some.

"c";"Pumpkin Seeds";""
"tb";"Horseradish";""
"c";"Puffed Quinoa";""
"c";"Honey";""
"c";"sesame seeds";""
"";"Red Onion";""
"ts";"Spicy Mustard";""
"c";"Dry Oatmeal";""
"c";"Ketchup";""
"ts";"Pepper";""
"tb";"Brown Sugar";""
"c";"Pecans";""
"ts";"Dijon Mustard";""
"single";"Cadbury Flake Bar";""
"g";"Caster Sugar";""
"g";"Low-fat Mozzarella Cheese";""
"md";"Onion";""
"sm";"Whole-wheat Pita";""
"medium";"Lemon";""
"c";"Raisins";""
"c";"Almonds";""
"c";"Dates";""
"g";"Ham";""
"lb";"Ground Sirloin";""
"c";"Shredded Coconut";""
"c";"Sunflower Seeds";""
"";"Tomato";""

The function used to extract aisle is

CREATE OR REPLACE FUNCTION get_ing_aisle(bigint, bigint)
  RETURNS character AS
'SELECT get_aisle(aisle) as aisle FROM ingredient_owner WHERE ingredient=$1 and owner=$2'
  LANGUAGE 'sql' VOLATILE
  COST 100;

 

Cheers
