將5個查詢合併爲1

我有我運行的以下代碼（請參閱下圖中的輸出）。我試圖做的是將所有5個mysql_cteX表（其中X = 1,2,3,4,5）合併到一個完整的查詢表中。將5個查詢合併爲1

但是，輸出我得到的是這些，而不是1個整體合併表：

請幫助，我也不太清楚我做錯了什麼。我得到的錯誤消息是：消息208，級別16，狀態0，行25 無效的對象名'＃mysql_cte1'。

您正在創建臨時表，但未插入到它們中。只要調用select就不會將數據插入到它們中，而只是按照您所看到的顯示它們。 [插入示例]（https://www.tutorialspoint.com/sql/sql-insert-query.htm） – Ranjeet

如果所有表都具有相同的列數和通訊員數據類型

你可以使用聯盟「合併」表（如第一個3臺）,, UNION ALL合併所有的行.. UNION合併不同的行

    a.tickerid as '+quotename(Concat(@product, ' ', 'TickerID'))+',
