我想知道如何在函数内使用动态查询。我尝试了很多方法，但是，当我尝试编译我的函数时，会显示一条消息 SQL 42601。

我使用的代码：

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN
  WITH v_tb_person AS (return query execute sql)
  select name, count(*) from v_tb_person where nome like '%a%' group by name
  union
  select name, count(*) from v_tb_person where gender = 1 group by name;
END     
$$ LANGUAGE plpgsql;

我收到的错误消息：

ERROR:  syntax error at or near "return"
LINE 5:     WITH v_tb_person AS (return query execute sql)

我尝试使用：

WITH v_tb_person AS (execute sql)

WITH v_tb_person …

在PostgreSQL中存在一些使用批量收集的声明的方法,就像在Oracle中一样？

Oracle中的示例:

create or replace procedure prc_tst_bulk_test is

type typ_person is table of tb_person%rowtype;
v_tb_person typ_person;

begin

select *
bulk collect into v_tb_person
from tb_person;

-- make a selection in v_tb_person, for instance    
select name, count(*) from v_tb_person where age > 50
union 
select name, count(*) from v_tb_person where gender = 1

end;

谢谢
