[英]TYPO3: exec_SELECTquery with where clause
The following select
returns an empty result set, although it shoudn't: 以下
select
返回一个空结果集,尽管它不是:
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('*', 'tx_xmluploader_xml_import_tree', 'xml_import_id='.$xml_import_id);
$xml_import_id
is set. $xml_import_id
已设置。 And it works if I remove the where
clause.. 如果我删除
where
子句,它的工作原理..
Thanks 谢谢
I still don't understand why it doesn't work.. A simple workaround suggested by a coleague: 我仍然不明白为什么它不起作用。一个简单的解决方法由一个coleague建议:
// select all from the db
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('*', 'tx_xmluploader_xml_import_tree');
while( $entry = $GLOBALS['TYPO3_DB']->sql_fetch_assoc() )
{
if( $entry['xml_import_id'] == $xml_import_id ) {
....
}
}
First, make sure the following is set in localconf.php: 首先,确保在localconf.php中设置以下内容:
$TYPO3_CONF_VARS['SYS']['sqlDebug'] = '1';
$TYPO3_CONF_VARS['FE']['debug'] = '1';
Then try 然后试试
$res = $GLOBALS['TYPO3_DB']->SELECTquery('*', 'tx_xmluploader_xml_import_tree', 'xml_import_id='.$xml_import_id);
t3lib_div::debug($res);
Result is the output of the query in the frontend. 结果是前端中查询的输出。 You can then execute it in MySQL for debugging.
然后,您可以在MySQL中执行它以进行调试。
a) make sure $xml_import_id actually has a value (one which is in the database as well) a)确保$ xml_import_id实际上有一个值(一个也在数据库中)
b) Try this: b)试试这个:
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery(
'*',
'tx_xmluploader_xml_import_tree',
"xml_import_id='".$xml_import_id."'"
);
How do you process the result? 你如何处理结果? How does your expected $xml_import_id value look like?
您期望的$ xml_import_id值如何?
