postgres 循环记录检索语法错误

Question

我有这个引发错误的循环：

SQL 错误 [42601]：错误：“.”处或附近的语法错误位置：435

DO
$$DECLARE
declare 
s_row record;
sch cursor for
SELECT  distinct n.nspname as "schema"
FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE pg_catalog.array_to_string(c.relacl, E'\n') LIKE '%user123%';
begin
    open sch;
    loop
    fetch sch into s_row;
    exit when not found;
    REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA s_row.schema FROM partner_reporting_user3_to_delete;
    end loop;
close sch;
END;$$;

我以为我可以通过说 s_row.schema 来引用记录行内容，但我在这里遗漏了一些东西..

Answer 1

为此尝试动态 SQL。

...
EXECUTE format('REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA %I FROM partner_reporting_user3_to_delete;', s_row.schema);
...
