I have wriiten following simple function in postgresql
CREATE OR REPLACE FUNCTION "MySchema".add_user(p_name character varying,
p_email1 character varying, p_email2 character varying)
RETURNS bigint AS
$BODY$
DECLARE
userId bigint;
BEGIN
INSERT INTO "MySchema"."User"("Name" ,"EMail1" , "EMail2")
VALUES ($1 , $2, $3) ;
Select CURRVAL('"MySchema".user_seq_userid') into userId;
return userid;
END;
$BODY$
LANGUAGE plpgsql VOLATILE STRICT
Function works absoolutely fine if I provide values for all three parameters.
Record gets inserted too.
But if I pass NULL for say last parameter, using SELECT
"MySchema".add_user('A' , 'A', NULL)
function does not do anything and return zero.
No error is shown. But record is not inserted in table.
All columns in table can have NULL value.
