Question

我正在尝试使用以下查询在Joomla系统中进行全文搜索：

SELECT `id`,`user_id`,`article_id`,`body`,`created_time`
FROM `#__user_notes`
WHERE (`user_id` = '660' AND `article_id` IN (23, 24) AND `id` < '385') 
OR (MATCH (body) AGAINST (`test`) AND `id` < '385' AND `user_id` = '660')
ORDER BY id DESC LIMIT 10

抛出此错误：

JDatabaseExceptionExecuting: Unknown column 'test' in 'where clause'

在没有全文搜索行的情况下工作正常：

OR (MATCH (body) AGAINST (`test`) AND `id` < '385' AND `user_id` = '660')

我已将ENGINE设置为MYISAM，因为此答案建议fulltext query in joomla

Answer 1

您应该从查询中删除反引号。

OR (MATCH (body) AGAINST (`test`) AND `id` < '385' AND `user_id` = '660')

上方应替换为

OR (MATCH (body) AGAINST ('test') AND `id` < '385' AND `user_id` = '660')

Mysql使用反引号作为列名，但是test是您要搜索的文本。

因为您正在使用Joomla，所以在Joomla中应该使用$db->quoteName而不是$db->quote。 quoteName用于转义列名，quote用于值

SQL全文搜索-“ where子句”中的未知列“ test”
