2012-06-13 10:42 sqlserver中CONTAINS用法

本文介绍了CONTAINS语法在全文本检索中的应用,通过多个实例演示了如何进行精确匹配、逻辑组合检索、位置敏感检索、通配符检索及加权检索等技巧。
CONTAINS 语法
我们通常在 WHERE 子句中使用 CONTAINS ,就象这样:SELECT * FROM table_name WHERE CONTAINS(fullText_column,'search contents')。

我们通过例子来学习,假设有表 students,其中的 address 是全文本检索的列。
1. 查询住址在北京的学生
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, 'beijing' )
remark: beijing是一个单词,要用单引号括起来。

2. 查询住址在河北省的学生
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, '"HEIBEI province"' )
remark: HEBEI province是一个词组,在单引号里还要用双引号括起来。

3. 查询住址在河北省或北京的学生
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, '"HEIBEI province" OR beijing' )
remark: 可以指定逻辑操作符(包括 AND ,AND NOT,OR )。

4. 查询有 '南京路' 字样的地址
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, 'nanjing NEAR road' )
remark: 上面的查询将返回包含 'nanjing road','nanjing east road','nanjing west road' 等字样的地址。
A NEAR B,就表示条件: A 靠近 B。

5. 查询以 '湖' 开头的地址
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, '"hu*"' )
remark: 上面的查询将返回包含 'hubei','hunan' 等字样的地址。
记住是 *,不是 %。

6. 类似加权的查询
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, 'ISABOUT (city weight (.8), county wright (.4))' )
remark: ISABOUT 是这种查询的关键字,weight 指定了一个介于 0~1之间的数,类似系数(我的理解)。表示不同条件有不同的侧重。

7. 单词的多态查询
SELECT student_id,student_name
FROM students
WHERE CONTAINS( address, 'FORMSOF (INFLECTIONAL,street)' )
remark: 查询将返回包含 'street','streets'等字样的地址。
对于动词将返回它的不同的时态,如:dry,将返回 dry,dried,drying 等等。

以上例子都使用英文,不使用中文是因为有的查询方式中文不支持,而且我的计算机是英文系统。
