Question

我想创建一个查询，它可以在我的＆＃34;条件＆＃34;中使用短语的单词。（像谷歌一样）

实施例：我的短语：＆＃39; Foo Bar Test＆＃39;

我的数据库表：

|柱|

＆＃39;嗨Bar＆＃39;

＆＃39;测试栏＆＃39;

＆＃39; Hi Foo＆＃39;

＆＃39;这里没什么＆＃39;

＆＃39; Foo再次＆＃39;

我等待的结果：

|柱|

＆＃39;嗨Bar＆＃39;

＆＃39;测试栏＆＃39;

＆＃39; Hi Foo＆＃39;

＆＃39; Foo Again＆＃39;

Answer 1

您可以在Sql server中使用FULL Text Index执行此操作。也可以使用split string函数实现

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 + '%'

Answer 2

任何分组/解析功能都可以提供帮助

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

UDF（如果需要）

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',' ')
