I have a script migrating from oracle to Postgres. I have checked online and don't see anything wrong on for ... loop statement. Would you please tell me what is wrong where?
CREATE OR REPLACE FUNCTION "CIDRDBA"."CIDRDBA_CONSTRAINTS" ( val in varchar(4000) ) RETURNS VOID
as $$
begin
if val = 'DISABLE' then
raise notice '%', 'CIDRDBA Constarints are being disabled';
for c in ( select table_name, constraint_name from information_schema.table_constraints
where constraint_type = 'R' )
loop
raise notice '%', 'Processing table: ' || c.table_name || ' - constraint
' || c.constraint_name;
execute immediate 'alter table ' || c.table_name ||' ' || val || ' constraint
' ||
c.constraint_name ;
end loop;
for c in ( select table_name, constraint_name from information_schema.table_constraints
where constraint_type = 'P' )
loop
raise notice '%', 'Processing table: ' || c.table_name || ' - constraint
' || c.constraint_name;
execute immediate 'alter table ' || c.table_name || ' ' || val || ' constrain

c.constraint_name ;
end loop;
elsif val = 'ENABLE' then
raise notice '%', 'CIDRDBA Constarints are being enabled';

To call him a dog hardly seems to do him justice though in as much as he had four legs, a tail, and barked, I admit he was, to all outward appearances. But to those who knew him well, he was a perfect gentleman (Hermione Gingold)
