使用短语SQL Server查询查询单词

Question

我想创建一个查询，它将能够在我的"标准"中使用一个短语的单词(像谷歌一样)

的例子:我的短语:'Foo Bar Test'

我的数据库表:

| |列

"你好棒"

测试棒的

"嗨Foo"

"也没有"

再次"Foo"

我正在等待的结果:

| |列

"你好棒"

测试棒的

"嗨Foo"

再次"Foo"

Answer 1

任何拆分/解析函数都可以提供帮助

Declare @YourTable table (YourFieldName varchar(100))
Insert Into @YourTable values
('Hi Bar'),
('Test Ba'),
('Hi Foo'),
('Nothing here'),
('Foo again')
Declare @SearchString varchar(max) = 'Foo Bar Test'
Select A.*
 From  @YourTable A
 Join  [dbo].[udf-Str-Parse](@SearchString,' ') B
   on  Charindex(RetVal,YourFieldName)>0

返回

YourFieldName
Hi Foo
Foo again
Hi Bar
Test Ba

如果需要的话UDF

CREATE FUNCTION [dbo].[udf-Str-Parse] (@String varchar(max),@Delimiter varchar(10))
Returns Table 
As
Return (  
    Select RetSeq = Row_Number() over (Order By (Select null))
          ,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
    From (Select x = Cast('<x>'+ Replace(@String,@Delimiter,'</x><x>')+'</x>' as xml).query('.')) as A 
    Cross Apply x.nodes('x') AS B(i)
);
--Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
--Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')

您可以在Sql server中使用FULL Text Index来完成此操作。也可以使用拆分字符串函数来实现

Declare @str varchar(500) = 'Foo Bar Test'
SELECT distinct tc.*
FROM   (VALUES ('Hi Bar' ),
               ('Test Bar' ),
               ('Hi Foo' ),
               ('Nothing here' ),
               ('Foo again' ) ) tc (columnss)
       JOIN [dbo].[Delimitedsplit8k](@str, ' ') f
         ON columnss LIKE '%' + f.Item + '%'
