我怎么能从一个领域(SQL)中看到一行?
原标题:How do I get all rows that contains a string in a field (SQL)?

我有一个叫作文章的表格,我想检索到在<代码>Tags领域包含标记的所有文章。 <代码>Tags 外地载有一套经限定的座标。

如果我试图找到一个包含标签php的文章。 它应当从一张表格中收回有一条规定的结果。 a. 看起来如此的塔格领域:

  • php
  • c++,php,python

如果我在PHP中这样做的话,我会简单地利用探索,但我不想通过数据库中的每一行,而是使用更有效的方法。

最佳回答

您可以使用同样的经营者。

select * from articles where tag like  %php% 

如果你对不属于营地但拥有像Aphphp这样的营地的广场感到担忧,那么你就可以使用 com子。

select * from articles where tag like  %php,%  or tag like  %,php% 
问题回答

it match:

  1. php
  2. randomwordphp
  3. phprandomword
  4. randomphpword

学历

SELECT *
FROM articles
WHERE articleTags LIKE "%php%"

在Oracle, 您可使用Oracle text

简单地说,查询数据就象

select * from articles where contains(fieldName, contentText) > 0

关于Oracle文本的询问,请上http://docs.oracle.com/cd/B28359_01/text.111/b28303/query.htm>rel=“nofollow”>here
