请帮帮我，我有个问题：您的SQL语法有一个错误；检查与MySQL服务器版本相对应的手册，以了解第1行“as countPosts”附近使用的正确语法

SELECT users.id, users.name, users.email, users.avatar, users.about, users.birthday, users.gender, users.firstName, users.lastName, users.single, users.statement, users.mainTimelineId, media.preview as avatarMediaPreview, media.file as avatarMediaFile, media.fileType as avatarMediaFileType
              (select COUNT(id) from posts where posts.userId=121) as countPosts,
              (select COUNT(id) from followers where toId=121) as countFollowers,
              (select COUNT(id) from followers where fromId=121) as countFollowing,
              (select COUNT(id) from connections where fromId=121 or toId=121) as countConnections,
              (select id from followers where fromId=121 and toId=121) as followId
              FROM users
              LEFT JOIN media ON media.id = users.avatarMediaId 
              WHERE users.id=121


，
在
avatarMediaFileType
之后丢失。您也可以在子查询上使用
users.id
而不是
121
，这样您就不必在每个子查询上重复id。
