Postgresql 错误：运算符不存在：整数integer[]

我试图创建一个函数，其中我传递一个数组作为参数

当我尝试执行该函数时，出现以下错误：

[2020-12-07 13:53:58] [42883] ERROR: operator does not exist: integer <> integer[]
[2020-12-07 13:53:58] Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
[2020-12-07 13:53:58] Where: PL/pgSQL function vectors_paginated(uuid,text,integer[]) line 16 at IF

我做错了什么？

不在不能与数组一起使用，您需要使用vector.actor\u键入所有actors

但我认为，通过将条件放在WHERE中，并摆脱缓慢而低效的逐行处理，可以大大简化整个功能：

CREATE OR REPLACE FUNCTION vectors_paginated(analysisId uuid, vectorName text, actors int[])
  RETURNS SETOF vectors  
AS 
$$
  SELECT aiv.*
  FROM vectors AS aiv
  WHERE aiv.analysis_id = analysisId
    AND (vectorName is NULL OR Lower(aiv.name) NOT LIKE '%' || Lower(vectorName) || '%')
    AND (actors IS NULL OR aiv.actor_type <> ALL (actors));
$$
language SQL;

您向我们展示的代码中没有任何内容。这是我拥有的完整脚本。我假设它与我传递参数的方式有关，我添加了其余的参数

CREATE OR REPLACE FUNCTION vectors_paginated(analysisId uuid, vectorName text, actors int[])
  RETURNS SETOF vectors  
AS 
$$
  SELECT aiv.*
  FROM vectors AS aiv
  WHERE aiv.analysis_id = analysisId
    AND (vectorName is NULL OR Lower(aiv.name) NOT LIKE '%' || Lower(vectorName) || '%')
    AND (actors IS NULL OR aiv.actor_type <> ALL (actors));
$$
language SQL;
