搜索用逗号分隔值的列 [英] Searching a column with comma separated values

问题描述

我有SQL Server 2008 R2的版本，这很努力和净网​​页作为前端。

来到了该问题，是基本上由用逗号分隔的各种技能的数据库中的列。例如，某些候选人有3种不同的技能，即设置 C＃， SQL服务器，的Oracle 。谁希望列出同时具有的技能候选人的用户 C＃和甲骨文将提供输入作为在网页上的文本框C＃，甲骨文。我想编写一个查询，可以列出这样的。我曾尝试自由文本搜索。但它未能提取若资本/小词，为通配符的支持，技能甚至秩序。

下面是示例查询

  SELECT * FROM型材，其中自由文本（技能，'C＃，甲骨文）
 

解决方案

从我的POV正确的（和不受欢迎的）答案是重新设计你的表结构：你永远也不会有值的列表中的一个字段，如果你要分别访问它们。

I have SQL server 2008 r2 edition, which am working on and a .Net webpage as front end.

Coming to the issue, there is a column in the database which basically consists of various skill sets separated by a comma. For example some candidate has a 3 different skill sets namely C#, SQL server, Oracle. The user who wants to list the candidates having the skills of both C# and Oracle will provide the input as C#, Oracle in a text box on the webpage. I want to write a query which can list out such. I have tried freetext search. But it fails to fetch if in Capital/small words, no support for wildcard character, even the order of skills.

Below is the sample query

Select * from profiles where freetext(skills, ‘C#,Oracle’)

解决方案

From my POV the correct (and unwelcome) answer is to redesign your table structure: You should never ever have a list of values in a single field, IF YOU WANT TO ACCESS THEM SEPARATELY.
