Return 个 values 由 Postgresql 中的集合组成
Return values consisting of the set in Posgresql
我使用https://github.com/kyleconroy/sqlc生成代码。我想 return human_id 使用 group_id 数组。
-- name: HumansByGroupID :many
SELECT human_id FROM groups
WHERE group_id IN (UNNEST(::uuid[]));
return
ERROR: set-returning functions are not allowed in WHERE (SQLSTATE 0A000)
在我的理解中,... IN (UNNEST(::uuid[]));
变成了IN ('...','...','...');
您可以执行以下操作:
WHERE group_id IN (SELECT col FROM UNNEST(::uuid[]) AS col);
或者,您也可以这样做:
WHERE group_id = ANY (::uuid[]);
