MySQL錯誤1242甚至與任何

Question

我開始使用OpenGeoDB查找郵政編碼和城市名稱。我的MySQL查詢內容是這樣的：

SELECT  `d`.`text_val` AS `city`, (
    SELECT `text_val` 
    FROM `geodb_textdata` 
    WHERE `loc_id` = ANY (
     SELECT `loc_id` 
     FROM `geodb_textdata` 
     WHERE `text_val` LIKE '08%' 
    ) 
     AND `text_type` = '500300000' 
) AS `plz`, `c`.`lat`, `c`.`lon` 
FROM  `geodb_textdata` AS `d` 
LEFT JOIN `geodb_coordinates` AS `c` USING (`loc_id`) 
WHERE  `loc_id` = ANY (
    SELECT `loc_id` 
    FROM `geodb_textdata` 
    WHERE `text_val` LIKE '08%' 
) 
    AND `text_type` = '500100000' 

如果我運行此查詢採用了全郵政編碼或城市名稱它的偉大工程，但上面的代碼中，我得到的錯誤代碼

#1242 - Subquery returns more than 1 row 

我正在使用Google，我發現，我應該在=和子查詢之間使用ANY。你有什麼想法我可以修復我的代碼？先謝謝你。 :)

我懷疑這個子查詢返回超過1行：

(
SELECT `text_val` 
FROM `geodb_textdata` 
WHERE `loc_id` = ANY (
    SELECT `loc_id` 
    FROM `geodb_textdata` 
    WHERE `text_val` LIKE '08%' 
) 
    AND `text_type` = '500300000' 
) AS `plz` 

更新：未經測試，但給這個查詢一個嘗試。

SELECT  `d`.`text_val` AS `city`, `d2`.`text_val` AS `plz`, `c`.`lat`, `c`.`lon` 
FROM  `geodb_textdata` AS `d` 
LEFT JOIN `geodb_textdata` AS `d2` USING (`loc_id`) 
LEFT JOIN `geodb_coordinates` AS `c` USING (`loc_id`) 
WHERE  `d`.`text_val` LIKE '08%' AND `d`.`text_type` = '500100000' 
AND   `d2`.`text_val` LIKE '08%' AND `d2`.`text_type` = '500300000'
