存儲過程：數據截斷：截斷不正確DOUBLE值

我缺乏經驗，構建存儲過程也碰到了這個錯誤，我不明白背後的原因：存儲過程：數據截斷：截斷不正確DOUBLE值

[2015年9月29日1時01分55秒] [22001] [1292]數據截斷：截斷不正確DOUBLE值： '5609d3e6c89be'

值 '5609d3e6c89be' 是「FLIGHTID」。

我的存儲過程的代碼：

DROP PROCEDURE IF EXISTS initFlight; 
CREATE PROCEDURE initFlight (flightid VARCHAR(50)) 
BEGIN 

    -- rules, player should only fly if not in jail, not in missions 
    -- and is in the city the flight will take off from 
    DECLARE fname VARCHAR(50); -- flight name 
    DECLARE depart int; -- city number of departure 
    DECLARE dest int; -- city number of destination 

    -- assign values to our variables 
    select flightname, source_airport, destination_airport 
    into fname, depart, dest 
    from airport_flights where id = flightID; 

    -- show in console the variable values for debugging 
    -- select concat(" fname: ", fname, " depart: ", depart, " dest: ", dest); 

    -- set players flying means p.live = '-1' 
    update `[players]` as p set p.live = '-1' where p.id in (
    select id from airport_tickets where flight = flightID 
) and p.live = depart; 

    -- insert into alerts a message for players boarding the flight (are in the city of departure) 
    insert into player_alerts (alert_text, player_id) 
    select concat("Boarding flight ", fname) as alert_text, p.id as player_id from `[players]` as p 
    where p.id in (
     select id from airport_tickets where flight = flightID 
    ) and p.live = depart; 

    -- insert into alerts a message for players that missed the flight (are not in the city of departure) 
    insert into player_alerts (alert_text, player_id) 
    select concat("You missed flight ", fname) as alert_text, id as player_id from `[players]` as p 
    where p.id in (
     select id from airport_tickets where flight = flightID 
    ) and p.live != depart; 

    -- stop sales 
    update airport_flights set selling_tickets = 0 where id = flightID; 

END; 
call initFlight('5609d3da016bf');

這到底是怎麼回事？爲什麼我的「字符串」被轉換爲雙精度，然後被截斷？

airport_flights.id is varchar(50) 
airport_flights.source_airport is int(11) 
airport_flights.destination_airport is int(11) 

airport_tickets.id is varchar(50) 
airport_tickets.flight is varchar(50) 
airport_tickets.owner_id is int(11) 


`[players]`.id is int(11) 
`[players]`.live is int(11) 
`[players]`.name is varchar(200) 

player_alerts.id is int(11) 
player_alerts.alert_text is varchar(250)

PS：如果你需要更多的信息，讓我知道和批評是一如既往歡迎

如果你把球員表也放在一起，這將有所幫助。 – e4c5

從http://stackoverflow.com/questions/26743197/err-1292-truncated-incorrect-double-value：**這是真正蹩腳的錯誤之一，可能與實際問題沒有任何關係。**是否知道該過程中的哪個查詢出錯？ – Barmar

現在添加播放器字段。至於錯誤的查詢，我不知道，這些查詢是由1，然後結合到存儲過程，有沒有辦法來調試呢？ –
