創建一個存儲過程來返回一個機場列表lat和long

Question

這是我到目前爲止，但我不能讓它正常運行。我不斷收到語法不正確的錯誤ON FROM FROM TBL_AIRPORT AIR。但我無法弄清楚應該在那裏，或者改變什麼，所以我不能運行它。任何幫助，將不勝感激。

重寫你select條款，因爲你用「TBL_AIRPORT」表兩次相同的關鍵字「FROM」，並還適當編寫開始，提交事務的語法。

SELECT 
    GEOLOCATION.LAT, GEOLOCATION.LONG, ICAOCODE, IATACODE, STRNAME, 
    STRCITY, COUNTRY.COUNTRYNAME, INT_ELEVATION 
FROM 
    TBL_AIRPORT AIR 
JOIN 
    TBL_COUNTRY C ON C.COUNTRY_ID = AIR.COUNTRY_FK 
WHERE 
    GEOLOCATION.LAT <> 0 OR GEOLOCATION.LONG <> 0
