Question

我试图建立一个联合，其中一列是带时区的时间戳。

 UNION(SELECT au.accountId AS accountid, 
                                u.id AS userId,
                                CAST (NULL AS INTEGER) AS searchprofileid,
                                u.name, 
                                u.email AS email, 
                                3 as searchitemtype,                                  
                                ac.name AS accountname,
                                null AS searchprofiletype,
                                false AS isdeleted,
                                false AS hashostednewsroom,
                                u.lockoutenabled AS lockoutenabled,
                                u.lockoutend AS lockoutend
                            FROM users u                              
                            LEFT JOIN accountusers au
                            ON u.id = au.userid
                            LEFT JOIN accounts ac
                            ON au.accountid = ac.id
                            WHERE u.name ILIKE '%%'
                            OR u.email ILIKE '%%'
                            LIMIT 5)ORDER BY

这是一个更大的联盟的一部分，但我得到了这个错误：

UNION类型文本和时区与时区无法匹配

所以我把它投射到像这样的文本u.lockoutend :: text AS lockoutend 这确实有效，但是当我尝试将字符串解析为DateTimeOffset时，我的后端（C＃）失败了？。为什么要将lockoutend作为文本？我怎么能这样做？

编辑

CREATE TABLE public.users
(
  id integer NOT NULL DEFAULT nextval('users_id_seq'::regclass),
  accessfailedcount integer NOT NULL,
  concurrencystamp character varying(255) COLLATE pg_catalog."default",
  email character varying(128) COLLATE pg_catalog."default",
  emailconfirmed boolean NOT NULL,
  lockoutenabled boolean NOT NULL,
  lockoutend timestamp with time zone,
  name character varying(128) COLLATE pg_catalog."default",
  normalizedemail character varying(128) COLLATE pg_catalog."default",
  normalizedusername character varying(128) COLLATE pg_catalog."default",
  passwordhash character varying(512) COLLATE pg_catalog."default",
  phonenumber character varying(50) COLLATE pg_catalog."default",
  phonenumberconfirmed boolean NOT NULL,
  securitystamp character varying(255) COLLATE pg_catalog."default",
  twofactorenabled boolean NOT NULL,
  username character varying(50) COLLATE pg_catalog."default",
  locale integer NOT NULL DEFAULT 1,
  CONSTRAINT users_pkey PRIMARY KEY (id)
  )

C＃

   using (var dbConnection = _dapperConnection.Open())
        {
            _logger.LogDebug("Executing AdminSearchRepository.AdminSearch {sql}", sql);
            return await dbConnection.QueryAsync<DapperAdminSearchDto>(sql);
        }

DapperAdminSearchDto的一部分：

   public bool LockoutEnabled { get; set; }
    public DateTimeOffset? LockoutEnd { get; set; }

POSTGRES与时区的时间戳联合
