[英]SQL Server Full Text Search to find containing characters
I have a table with a column Document
that is FullText Index. 我有一个表,其中有一个Document
为全文索引的列。 Let say I have this in this table: 可以说我在这张桌子上有这个:
| ID | Document |
| 1 | WINTER SUMMER SPRING OTHER |
My requirement is to find rows that contains 'ER'. 我的要求是找到包含“ ER”的行。
For this I am querying like this: 为此,我这样查询:
SELECT TOP 100
[FullTextSearch].[Document], [FullTextSearch].[ID]
FROM
[FullTextSearch]
WHERE
CONTAINS(Document, '"*ER*"')
But this is not working. 但这是行不通的。
Please suggest what should be best way to do this using FullTextSearch. 请提出使用FullTextSearch的最佳方法。
I am expecting id 1 should be returned. 我希望应该返回ID 1。
You can user LIKE operator to find the value. 您可以使用LIKE运算符来查找值。
The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. 在WHERE子句中使用LIKE运算符在列中搜索指定的模式。
There are two wildcards used in conjunction with the LIKE operator: LIKE运算符与两个通配符一起使用:
% - The percent sign represents zero, one, or multiple characters _ - The underscore represents a single character %-百分号表示零个,一个或多个字符_-下划线表示单个字符
Syntax, 句法,
SELECT column1, column2, ... FROM table_name WHERE columnN LIKE pattern; SELECT column1,column2,... FROM table_name WHERE columnN LIKE模式;
This query can help to find the result. 该查询可以帮助找到结果。
SELECT Document,ID FROM FullTextSearch WHERE Document LIKE '%ER%'; 从FullTextSearch中选择文档,ID,其中文档类似于'%ER%';
It's a wildcard query...This should work. 这是一个通配符查询...这应该工作。
SELECT TOP 100
[FullTextSearch].[Document], [FullTextSearch].[ID]
FROM
[FullTextSearch]
WHERE
Document like '%ER%'
========OR============= ======== OR =============
SELECT TOP 100
[FullTextSearch].[Document], [FullTextSearch].[ID]
FROM
[FullTextSearch]
WHERE
CONTAINS(Document, '%ER%')
