Javascript 从联接表中选择计数

我正在尝试选择每个帖子的赞数。在我的代码中，表是T3。我似乎不能得到想要的结果，我不确定为什么。请帮忙

function timeLineSql(Id, ifRoute) {
  var preparedStatement, query;
  ifRoute == "post" ? 
  (preparedStatement = [Id, lastIdOfPosts],  query = "SELECT T1.postTitle, T1.youtubeUrl, T1.posterId, T1.textarea, T1.category, T1.postTime, T1.id, T2.name, T2.title, T2.pathToProfilePicture, COUNT(T3.likerId) FROM posts AS T1 " +
  "JOIN likes AS T3 ON T3.idOfPost = T1.id " +
  "JOIN singleHorizontal AS T2 ON T1.posterId = T2.id AND T1.posterId = ? AND T1.id > ? ORDER BY T1.id LIMIT 1")
  : (preparedStatement = [Id],  query = "SELECT T1.postTitle, T1.youtubeUrl, T1.posterId, T1.textarea, T1.category, T1.postTime, T1.id, T2.name, T2.title, T2.pathToProfilePicture FROM posts AS T1 " + 
  "JOIN singleHorizontal AS T2 ON T1.posterId = T2.id AND T1.posterId = ? ORDER BY T1.id LIMIT 1");
  return { ps: preparedStatement, q: query };
}

您可能需要按（T3.idOfPost）分组，但这只是一个猜测。看起来您的

和

s应该是

WHERE

s。？我不知道你这是什么意思
