我现在有一个工作的MySQL查询我需要它转换为Typo3语法
SELECT
tt_news_tx_extendnews_subscriber_mm.uid_local,
fe_users.*
FROM fe_users
JOIN tt_news_tx_extendnews_subscriber_mm
ON tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid
WHERE tt_news_tx_extendnews_subscriber_mm.uid_local = 101
TYPO3
$res0 = $GLOBALS['TYPO3_DB']->exec_SELECT_mm_query(
'tt_news_tx_extendnews_subscriber_mm.uid_local,fe_users.*',
'fe_users',
'tt_news_tx_extendnews_subscriber_mm',
'tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid',
'tt_news_tx_extendnews_subscriber_mm.uid_local = 101',
'',
'',
''
);
结果是空的......有人知道这与typo3一起工作吗?
Debug带来:$ GLOBALS ['TYPO3_DB'] - > debug_lastBuiltQuery;
SELECT tt_news_tx_extendnews_subscriber_mm.uid_local,fe_users.*
FROM fe_users,tt_news_tx_extendnews_subscriber_mm,tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid
WHERE fe_users.uid=tt_news_tx_extendnews_subscriber_mm.uid_local
AND tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid.uid=tt_news_tx_extendnews_subscriber_mm.uid_foreign tt_news_tx_extendnews_subscriber_mm.uid_local = 101
答案 0 :(得分:4)
通过exec_SELECT_mm_query
,第4个参数是外键表名,而不是引用。你需要而不是:
tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid
仅
fe_users
在TYPO3 api : exec_SELECT_mm_query中查看更多详情。
我想,您可以尝试以下方法:
$res0 = $GLOBALS['TYPO3_DB']->exec_SELECT_mm_query(
'tt_news_tx_extendnews_subscriber_mm.uid_local,fe_users.*',
'tt_news',
'tt_news_tx_extendnews_subscriber_mm',
'fe_users',
'tt_news_tx_extendnews_subscriber_mm.uid_local = 101',
'',
'',
''
);
或者您可以使用以下小技巧完全使用SQL,因为exe_SELECTquery仅将您的字符串连接到SELECT..., FROM...
(等等......)部分。因此,您可以在JOIN
部分使用FROM
。
$res0 = $GLOBALS['TYPO3_DB']->exec_SELECTquery('tt_news_tx_extendnews_subscriber_mm.uid_local,fe_users.*',
'fe_users
JOIN tt_news_tx_extendnews_subscriber_mm
ON tt_news_tx_extendnews_subscriber_mm.uid_foreign = fe_users.uid',
'tt_news_tx_extendnews_subscriber_mm.uid_local = 101',
'',
'',
'');
