I created a function abcd_insert() which inserts data into table abcd, which has 8 columns. The code inside the function looks similar to below :

BEGIN
INSERT INTO abcd
VALUES
(
x ,
y ,
select sum(count) from (select count(*) from a where a1 = x and a2 = y and a3 = 1 union all select count(*) from b where b1 = x and b2 = y and b3 = 1 ) as n1,
select sum(count) from (select count(*) from a where a1 = x and a2 = y and a2 = 2 union all select count(*) from b where b1 = x and b2 = y and b3 = 2 ) as n2 ,
select sum(count) from (select count(*) from a where a1 = x and a2 = y and a2 = 3 union all select count(*) from b where b1 = x and b2 = y and b3 = 3 ) as n3 ,
select sum(count) from (select count(*) from a where a1 = x and a2 = y and a2 = 4 union all select count(*) from b where b1 = x and b2 = y and b3 = 4 ) as n4 ,
select sum(count) from (select count(*) from a where a1 = x and a2 = y and a2 = 5 union all select count(*) from b where b1 = x and b2 = y and b3 = 5 ) as n5 ,
SELECT sum(q1) from
(SELECT CASE WHEN COUNT(1) > 0 THEN 1 ELSE 0 END as q1 FROM p1 where p11 = x and p12 = y union all
SELECT CASE WHEN COUNT(1) > 0 THEN 1 ELSE 0 END as q1 FROM p2 where p21 = x and p22 = y ) as q1
);
END;

‘x’ and ‘y’ are my input parameters whose values will be passed to the function abcd_insert(). a,b,p1 and p2 are tables within the same schema.
When I pass ‘x’ and ‘y’ to the function at run time, it throws error.
Can someone please tell me what I am doing wrong here.
