MySQL和PHP - 使用'LIKE'和'NOT LIKE'

我需要一些使用LIKE和NOT LIKE的帮助...我有一个查询，我通过WHERE子句通过基于我的请求变量来自另一个服务器。其中一个查询如下所示：MySQL和PHP - 使用'LIKE'和'NOT LIKE'

'CONNECT' => 
    "(detail_head.comment LIKE '%port%' 
     or detail_head.comment LIKE '%forward%' 
     or detail_head.comment LIKE '%connect%' 
     or detail_head.comment LIKE '%router%' 
     or detail_head.comment LIKE '%fire%wall%' 
     or detail_head.comment LIKE '%sonic%' 
    ) AND (
     detail_head.comment NOT LIKE '%report%' 
     OR detail_head.comment NOT LIKE '%portal%' 
    )",

您可以看到我使用了LIKE而不是LIKE。不幸的是，这种方式并不按照我希望的方式工作。我猜这是因为我要求PORT，但不是REPORT，所以无论如何它都给了我LIKE。

我想知道在这种情况下我应该做些什么。我正在考虑将另一个查询或数组作为“排除列表”使用。如果查询是LIKE语句，我可以在我的WHERE子句中使用'table_uid NOT IN（COMMA SEPARATED UID列表）'。

我有我的LIKE语句，我想排除：

$exclude_where_clauses = array(
     'CC'   => "(detail_head.comment LIKE '%ccb%') ", 
     'CONNECT'  => "(detail_head.comment LIKE '%report%' OR detail_head.comment LIKE '%portal%') ", 
     'EO'   => "(detail_head.comment LIKE '%OCU%' AND detail_head.comment LIKE '%KS%' AND detail_head.comment LIKE '%screen%' AND detail_head.comment LIKE '%term%') ", 
     'INVENTORY'  => "(detail_head.comment LIKE '%discount%') ", 
     'KS'   => "(detail_head.comment LIKE '%panel%' or detail_head.comment LIKE '%PMIX%' or detail_head.comment LIKE '%pmix%') ", 
     'OCUS'   => "(detail_head.comment LIKE '%document%') ", 
     'SALES'   => "(detail_head.comment LIKE '%point%') ", 
     'SECURITY'  => "(detail_head.comment LIKE '%km%') ", 
     'TERMS'   => "(detail_head.comment LIKE '%forward%' or detail_head.comment LIKE '%sales%' or detail_head.comment LIKE '%intermittent%' or detail_head.comment LIKE '%print%' or detail_head.comment LIKE '%de%min%' or detail_head.comment LIKE '%reciept%' or detail_head.comment LIKE '%time%') ", 
);

所以，到最后，我想转产我目前的查询阵列说"(detail_head.comment LIKE '%port%' or detail_head.comment LIKE '%forward%' or detail_head.comment LIKE '%connect%' or detail_head.comment LIKE '%router%' or detail_head.comment LIKE '%fire%wall%' or detail_head.comment LIKE '%sonic%') AND table_uid NOT IN(LIST OF COMMA SEPARATED UIDs) "

请张贴一个例子评论，也一样，所以我们可以看到在上下文中的“报告”和“端口”。 – 2013-05-13 13:35:43

另外请注意，我认为我最想做的事情是编码出来......我只是不确定它会如何工作： – brandoncluff 2013-05-13 13:36:30

$ exclude_where_clause = $ exclude_where_clauses [$ _ REQUEST ['count_request']]; $ not_like_qry =“SELECT detail_head.scr FROM detail_head WHERE detail_head.call_status！='c'AND call_origins_uid！= 5 AND $ exclude_where_clause”; $ qry。=“AND call_origins_uid！= 5 GROUP BY detail_head.scr”; $ dob-> setQuery（$ not_like_qry）; （$ dob-> fetch（MYSQL_ASSOC））{ $ rows [] = $ dob-> getRowAsArray（）; } foreach（$ rows as $ row）{ fputcsv（$ tmpdata，$ row，'|'）; } – brandoncluff 2013-05-13 13:37:51

试试这个：

'CONNECT' => " 
    ( detail_head.comment LIKE '%port%' 
    OR detail_head.comment LIKE '%forward%' 
    OR detail_head.comment LIKE '%connect%' 
    OR detail_head.comment LIKE '%router%' 
    OR detail_head.comment LIKE '%fire%wall%' 
    OR detail_head.comment LIKE '%sonic%' 
    ) 
    AND NOT (
      detail_head.comment LIKE '%ccb%' 
     OR detail_head.comment LIKE '%report%' 
     OR detail_head.comment LIKE '%portal%' 
     OR detail_head.comment LIKE '%OCU%' 
     OR detail_head.comment LIKE '%KS%' 
     OR detail_head.comment LIKE '%screen%' 
     OR detail_head.comment LIKE '%term%' 
     OR detail_head.comment LIKE '%discount%' 
     OR detail_head.comment LIKE '%panel%' 
     OR detail_head.comment LIKE '%PMIX%' 
     OR detail_head.comment LIKE '%pmix%' 
     OR detail_head.comment LIKE '%document%' 
     OR detail_head.comment LIKE '%point%' 
     OR detail_head.comment LIKE '%km%' 
     OR detail_head.comment LIKE '%forward%' 
     OR detail_head.comment LIKE '%sales%' 
     OR detail_head.comment LIKE '%intermittent%' 
     OR detail_head.comment LIKE '%print%' 
     OR detail_head.comment LIKE '%de%min%' 
     OR detail_head.comment LIKE '%reciept%' 
     OR detail_head.comment LIKE '%time%' 
    ) 
",

我不要相信这会更有效率（效率可能确实较低），但它可能是一种更合理地定义规格的方法 - 使用regexp()中的单词边界。

这将返回0：

SELECT 'foo report bar' REGEXP '[[:<:]]port[[:>:]]';

如果这返回1：

SELECT 'foo report bar' REGEXP '[[:<:]]report[[:>:]]';

MySQL has more info in the manual。（5.1手动链接）

根据手头任务的性质，以及这将对我的数据库服务器施加多少压力和多少压力，我可能会考虑添加字段或相关表以帮助我处理（当我插入数据时），所以我可以在事后以更轻的方式运行这样的报告 - 而不必在全文字段中进行繁重的文本处理。
