This is probably obvious but I am not seeing what is going wrong with
this function definition:
CREATE OR REPLACE FUNCTION "public"."cproc_hli" (bgtemp NUMERIC,
humidity NUMERIC, wspeed NUMERIC) RETURNS NUMERIC AS
IF ($1 < 25)
THEN
SELECT (10.66 * (0.28 * $2)+(1.3 * $1) - $3)
ELSE
SELECT (8.62 * (0.38 * $2) + (1.55 * $1) - (0.5 * $3) + (exp(- $3 + 2.4)))
END IF
LANGUAGE 'plpgsql' VOLATILE RETURNS NULL ON NULL INPUT SECURITY INVOKER;
ERROR: syntax error at or near "IF" at character 119
LINE 2: IF ($1 < 25)
I have tried with dollar quoting around the function body, changing the
maguage to sql and using CASE ... WHEN instead of IF , tried Brackets
and no brackets around the Boolean expression.. and a number of other
variations, as well as rereading the Documentation.
I have also tried not having aliases/names for the arguments.
In every case I always get the syntax error directly after "AS".
Can somebody point what is probably obvious.
Cheers
