解决了!请看下面的答案!
在我解释我的问题之前,我想为那些觉得这个问题太长的人道歉,但我觉得我必须提供一些细节,以使事情更清晰。虽然,问题很容易理解,但实施并不是那么简单。
我有3张桌子。
Hata和Icon包含我想要与包含文本的Succes链接的图像
[畑]
id, INTEGER, AUTO_INCREMENT, PRIMARY_KEY
hata Image
idLang, VARCHAR(5)
[ICON]
id, INTEGER, AUTO_INCREMENT, PRIMARY_KEY
icon, IMAGE
idPhrase, INTEGER
[SUCCES]
id, INTEGER, AUTO_INCREMENT, PRIMARY_KEY
idPhrase, INTEGER
titre, VARCHAR(25)
desc, VARCHAR(125)
idLang, VARCHAR(5)
以下示例显示了Succes表的外观
+----+----------+-----------------+------------------+--------+
| id | idPhrase | titre | desc | idLang |
+----+----------+-----------------+------------------+--------+
| 1 | 1 | Hello | Desc in English | en-GB |
+----+----------+-----------------+------------------+--------+
| 2 | 1 | Salut | Desc in French | fr-FR |
+----+----------+-----------------+------------------+--------+
| 3 | 1 | 今日は | Desc in Japanese | ja-JP |
+----+----------+-----------------+------------------+--------+
| 4 | 2 | Goodbye | Desc in English | en-GB |
+----+----------+-----------------+------------------+--------+
| 5 | 2 | Au revoir | Desc in French | fr-FR |
+----+----------+-----------------+------------------+--------+
| 6 | 2 | またね | Desc in Japanese | ja-JP |
+----+----------+-----------------+------------------+--------+
| 7 | 3 | You're welcome | Desc in English | en-GB |
+----+----------+-----------------+------------------+--------+
| 8 | 3 | Je vous en prie | Desc in French | fr-FR |
+----+----------+-----------------+------------------+--------+
| 9 | 3 | どういたしまして | Desc in Japanese | ja-JP |
+----+----------+-----------------+------------------+--------+
...
现在使用此 WHERE 条件
连接表格Icons.idPhrase = Succes.idPhrase AND Hata.idLang = Succes.idLang
如果Succes表中没有任何具体内容,那么一切都会好的。
事实上,对于每个Icon,有3个句子,idPhrase链接它们,但在实际结果集中,我不知何故有冗余。
Icon1|FlagIcon1|TitreLang1|DescLang1
Icon1|FlagIcon2|TitreLang2|DescLang2
Icon1|FlagIcon3|TitreLang3|DescLang3
Icon2|FlagIcon1|TitreLang1|DescLang1
Icon2|FlagIcon2|TitreLang2|DescLang2
Icon2|FlagIcon3|TitreLang3|DescLang3
...
我想要实现的目标如下(只是第一行):
Icon1|FlagIcon1|TitreLang1|DescLang1|FlagIcon2|TitreLang2|DescLang2|FlagIcon3|TitreLang3|DescLang
或
Icon1|FlagIcon1|FlagIcon2|FlagIcon3|TitreLang1|DescLang1|TitreLang2|DescLang2|TitreLang3|DescLang3
甚至
Icon1|FlagIcon1|FlagIcon2|FlagIcon3|TitreLang1|TitreLang2|TitreLang3|DescLang1|DescLang2|DescLang3
换句话说,就像我一起加入了几个问题,例如
SELECT icon FROM Icon
加入
SELECT Hata.hata AS fEN, Succes.titre AS tEN, Succes.desc AS dEN
FROM Hata, Succes
WHERE Hata.idLang=Succes.idLang AND Succes.idLang='en-GB'
加入
SELECT Hata.hata AS fFR, Succes.titre AS tFR, Succes.desc AS dFR
FROM Hata, Succes
WHERE Hata.idLang=Succes.idLang AND Succes.idLang='fr-FR'
依旧...... 只是确保表格之间链接的问题(图标1和句子1)
这是另一个关于它应该(可能)如何的样本
+-------+-------+-------+-------+----------------+------------------+------------+-----------------+----------------+------------------+
| icon | fEN | fFR | fJP | tEN | tFR | tJA | dEN | dFR | dJA |
+-------+-------+-------+-------+----------------+------------------+------------+-----------------+----------------+------------------+
| <img> | <img> | <img> | <img> | Hello | Salut | 今日は | Desc in English | Desc in French | Desc in Japanese |
+-------+-------+-------+-------+----------------+------------------+------------+-----------------+----------------+------------------+
| <img> | <img> | <img> | <img> | Goodbye | Au revoir | またね | Desc in English | Desc in French | Desc in Japanese |
+-------+-------+-------+-------+----------------+------------------+------------+-----------------+----------------+------------------+
| <img> | <img> | <img> | <img> | You're welcome | Je vous en pries | どういたしまして | Desc in English | Desc in French | Desc in Japanese |
+-------+-------+-------+-------+----------------+------------------+------------+-----------------+----------------+------------------+
...
我已经浏览过SQL引用尝试很多东西,但它们似乎没有按照我的预期进行(CONCATENATE,UNION等...) 我也尝试了以下查询,但它给了我一条错误信息。
SELECT Icon.icon, Hata.hata AS fEN,Hata.hata AS fFR,Hata.hata AS fJA
,'FR'.'titre', 'FR'.'desc'
,'JA'.'titre', 'JA'.'desc'
,'UK'.'titre', 'UK'.'desc'
FROM Hata, Icon
LEFT JOIN Succes AS FR ON 'FR'.'idLang' = 'Hata'.'idLang' AND 'FR'.'idLang' = 'fr-FR'
LEFT JOIN Succes AS JA ON 'JA'.'idLang' = 'Hata'.'idLang' AND 'FR'.'idLang' = 'ja-JP'
LEFT JOIN Succes AS UK ON 'UK'.'idLang' = 'Hata'.'idLang' AND 'FR'.'idLang' = 'en-GB'
消息是
Statut SQL: HY000
Error Code: 1000
syntax error, unexpected $end, expecting BETWEEN or IN or SQL_TOKEN_LIKE
但根据我在StackOverflow上发现的样本,我的语法似乎很好。 我还必须指定我正在使用OpenOffice Base,我的目的是发布文档。也许有一些特定于OOo的东西,例如LEFT JOIN没有实现,但代码变色,所以我认为应该没问题。
感谢您的支持和帮助。

我真的不明白。 我尝试使用MySQL,它做了类似于独占连接的东西
mysql> SELECT titre AS tfr, titre AS ten, titre AS tjp FROM data WHERE idlang=1
-> UNION
-> SELECT null,titre AS ten, null FROM data WHERE idlang=2
-> UNION
-> SELECT null, null, titre as tjp FROM data WHERE idlang=3;
+------------------+------------------+------------------+
| tfr | ten | tjp |
+------------------+------------------+------------------+
| Salut | Salut | Salut |
| Au revoir | Au revoir | Au revoir |
| Je vous en pries | Je vous en pries | Je vous en pries |
| NULL | Hello | NULL |
| NULL | Goodbye | NULL |
| NULL | You're Welcome | NULL |
| NULL | NULL | Konnichiha |
| NULL | NULL | Mata ne |
| NULL | NULL | Douitashimashite |
+------------------+------------------+------------------+
9 rows in set (0.00 sec)
如果在第一个SELECT中我做了滴定AS tfr,为null,则列标题变为null。
mysql> SELECT titre AS tfr, titre AS ten, titre AS tjp FROM data WHERE idlang=1
-> UNION
-> SELECT null,titre AS ten, null FROM data WHERE idlang=2
-> UNION
-> SELECT null, null, titre as tjp FROM data WHERE idlang=3;
+------------------+------------------+------------------+
| tfr | NULL | NULL |
+------------------+------------------+------------------+
| Salut | NULL | NULL |
| Au revoir | NULL | NULL |
| Je vous en pries | NULL | NULL |
| NULL | Hello | NULL |
| NULL | Goodbye | NULL |
| NULL | You're Welcome | NULL |
| NULL | NULL | Konnichiha |
| NULL | NULL | Mata ne |
| NULL | NULL | Douitashimashite |
+------------------+------------------+------------------+
它看起来仍然不像我想要的结果。
我需要专注于那个数据表以获得所有的一行,但我一直想知道如何实现这一目标。原则上它很简单,但我不能在SQL中翻译它。
mysql> DESCRIBE data;
+-----------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| id_phrase | int(11) | YES | | NULL | |
| titre | varchar(20) | YES | | NULL | |
| desc | varchar(50) | YES | | NULL | |
| idicon | int(11) | YES | | NULL | |
| idlang | int(11) | YES | | NULL | |
+-----------+-------------+------+-----+---------+----------------+
6 rows in set (0.00 sec)
实际上idicon对于id_phrase是多余的(不需要它,所以假装它不存在)。
谢谢。

如果您遇到重新解决的问题,这里有一些提议。
注意:列名和表名可能与原始问题不同,但问题是相同的。
我一直在另一个论坛上提出这个问题,这里有2个我测试的查询,可以证明正在使用MySQL 5.5
查询1:
SELECT id_phrase
, idicon
, max(case idlang when 1 then titre end) AS tfr
, max(case idlang when 1 then DESC end) AS dfr
, max(case idlang when 2 then titre end) AS ten
, max(case idlang when 2 then DESC end) AS den
, max(case idlang when 3 then titre end) AS tjp
, max(case idlang when 3 then DESC end) AS djp
FROM DATA
WHERE idlang IN (1, 2, 3)
GROUP BY id_phrase, idicon
ORDER BY id_phrase ASC
查询2:
SELECT t1.id_phrase, t1.idicon, t1.titre AS tfr, t1.descr AS dfr, t2.titre AS ten, t2.descr AS den, t3.titre AS tjp, t3.descr AS djp
FROM DATA AS t1
LEFT OUTER JOIN DATA AS t2
ON t1.id_phrase=t2.id_phrase
LEFT OUTER JOIN DATA AS t3
ON t1.id_phrase=t3.id_phrase
WHERE t1.idlang=1 AND t2.idlang=2 AND t3.idlang=3
如果这些查询对您有所帮助,欢迎您。
