Question

我具有以下功能：

create or replace function getEdit (farm bigint [], retreat bigint [], dateLot date)
returns integer as $$
declare
qtde bigint = 0;
begin
select sum (e.est_qtde) into qtde
   from stocked and
   left join catanimal c on c.can_chave = e.can_chave
   left join farm f on f.faz_chave = e.faz_chave
  where e.cfg_chave = 1922
    and e.est_data <= $ 3
    and COALESCE (c.can_situation, 0) = 0
    and COALESCE (f.faz_situacao, 0) = 0
    and e.faz_chave in ($1::bigint[])
    and e.ret_key in ($2::bigint[]);
    return qtde;
end;
$$ language plpgsql;

当您称呼它时：

select * from getSet (array [19220200006, 19220200005], array [19220200005, 19220200004], '2019-03-01')

我收到以下错误：

ERROR: operator does not exist: bigint = bigint []
LINE 8: and e.faz_chave in ($ 1 :: bigint [])

我要去哪里错了？

Answer 1

对于数组，您需要使用ANY运算符：

and e.faz_chave = ANY (farm)
and e.ret_key = ANY (retreat);

无需将参数强制转换为已声明的类型。

带有数组参数的调用函数postgresql
