如何更改此视图，以便它可以在MS中使用

CREATE OR REPLACE VIEW users_with_meta_view AS
 SELECT
      u.id,
      u.user_login AS login,
      u.user_pass AS password,
      u.user_email AS email,
      (select meta_value from wp_usermeta where user_id = u.id and meta_key 
      = 'first_name' limit 1) as first_name,
      (select meta_value from wp_usermeta where user_id = u.id and meta_key 
      = 'last_name' limit 1) as last_name,
      (select meta_value from wp_usermeta where user_id = u.id and meta_key 
  = 'country' limit 1) as country
  FROM wp_users u

Answer 1

可能是：

SELECT
    u.id,
    u.user_login AS login,
    u.user_pass AS [password],
    u.user_email AS email,
    (select first(meta_value) from wp_usermeta where user_id = u.id and meta_key = 'first_name') As first_name,
    (select first(meta_value) from wp_usermeta where user_id = u.id and meta_key = 'last_name') As last_name,
    (select first(meta_value) from wp_usermeta where user_id = u.id and meta_key = 'country') As country
FROM 
    wp_users As u

如果备忘录出现问题，请尝试：

    (select first(Left(meta_value, 255)) from wp_usermeta where user_id = u.id and meta_key = 'first_name') As first_name,

或：

    (select top 1 meta_value from wp_usermeta where user_id = u.id and meta_key = 'first_name') As first_name,
