目前，它需要太多的時間，我覺得可能是不是一次又一次的重複代碼的一些更簡單的方法，但我不知道怎麼樣。

Answer 1

非常奇怪的查詢，但看起來像你正在做一個基於半小時增量的T1和T2值的數據透視表樣式查詢。我會堅持下去，直到預先聚合了獨特的行。由於您的「ts」列看起來代表「時隙」，並且半小時增量沒有變化，所以我會先將您的第一個查詢簡化爲下一個。

drop temporary table if exists inverted; 
create temporary table inverted as 
select 
     s.table_chart, 
     cast(s.name as char(30)) as name, 
     s.ename, 
     s.ts, 
     MAX(CAST(s.value_t1 as decimal(9,2)) as t1Val, 
     MAX(CAST(s.value_t2 as decimal(9,2)) as t2Val, 
     '#ffffff' as tsColor 
from 
    splitted_table s 
group by 
    s.table_chart, 
    s.name, 
    s.ename, 
    s.ts 

所以，現在，您可以在每個圖表，名稱，爲ename 24時隙行，但在自己的行已經預聚合。您的下一個UPDATE可以針對通用行進行簡化。我刪除了你的（小時，值，系列）列，因爲它們在最後一次插入之前沒有使用過，所以我在那裏添加了它們。

UPDATE inverted 
    SET tsColor = fn_rep_get_color_for_field(t1Val, t2Val, p_min, p_max) 
    where SUBSTRING(table_chart, 2, 1) = 'p'; 

UPDATE inverted 
    SET tsColor = fn_rep_get_color_for_field(t1Val, t2Val, q_min, q_max) 
    where SUBSTRING(table_chart, 2, 1) = 'q'; 

UPDATE inverted 
    SET tsColor = fn_rep_get_color_for_field(t1Val, t2Val, u_min, u_max) 
    where SUBSTRING(table_chart, 2, 1) = 'u'; 

現在，您可以透視。由於您的第一個查詢是按表格和名稱分組的，因此根據相應的T1或T2值獲取MAX（）值時，每個時隙/表格圖表/ eName只會有一條記錄。

現在，爲您的顏色。既然你從不查詢這些，他們甚至不會成爲你結果集的一部分，並且根據「p」，「q」或「u」值可能會有不同的值，你希望對其他... MIN，MAX，還是一個特別基於「u」的勝利？或者可能是「p」？你將不得不添加IF（）或case /當這樣的東西......

你的表結構將有基於你原來的樞軸查詢結構和CREATE LIKE條件，但由於你從來沒有插入到那些專欄，他們一直都是空白的。所以爲了您的額外時間，價值觀，系列欄目。

MAX(if(i.ts='00:30:00', 
     case when SUBSTR(i.table_chart, 2, 1) = 'p' then i.tsColor 
       when SUBSTR(i.table_chart, 2, 1) = 'q' then i.tsColor 
       ELSE i.tsColor end, 
     null)) as '0:30:00_Color', 
etc for rest of colors. 

希望這可以幫助您從另一個角度看到可能的解決方案。
