Question

以防万一，请允许我举一个例子以更好地理解。

DECLARE @HotelDes varchar(1000) = 'Wake up to breathtaking views of the iconic Sydney Opera House, the Harbour Bridge or Darling Harbour each morning. You will be spoiled for choice at the Shangri-La Hotel, with a day spa, fitness centre and indoor pool at your disposal. The Shangri-la Sydney is located in the historic Rocks area, where Europeans first settled in Australia in 1788. This enviable location is just 5 minutes’ walk from both the Sydney Opera House and the MCA (Museum of Contemporary Art). After a day of sightseeing, you can relax in the bathtub of your lavish marble bathroom. All rooms include free Wi-Fi and an iPod dock, as well as fluffy bathrobes and slippers. CHI, The Spa offers a luxurious escape in its private spa suites, with a range of body treatments and massages on offer. The hotel also offers a hot tub, sauna and sun deck so you can make the most of your stay. The award-winning Altitude Restaurant boasts magnificent views of the harbour. Café Mix offers international all-day dining, while the New York-inspired Blu Bar on 36 is the perfect spot for a creative cocktail.';
DECLARE @HotelCat varchar(200) = 'sauna';

所以我想要的是包含单词“ sauna”的字符串，并且该字符串将在两个句点之间。

我希望文本显示“酒店还提供热水浴池，桑拿浴室和日光浴平台，使您可以充分利用自己的住宿”。

我尝试过：

SELECT SUBSTRING(@HotelDes,CHARINDEX('.',@HotelDes)+1, CHARINDEX('.',@HotelDes,CHARINDEX('.',@HotelDes)+1) -CHARINDEX('.',@HotelDes)-1)

这将返回字符串“从第一个句点开始，您将被香格里拉大酒店所宠爱，并提供日间水疗中心，健身中心和室内游泳池”。

有人知道如何获取带有“桑拿”文本的字符串吗？

Answer 1

hsh.each do |key_value_pair|
  k, v = key_value_pair
  puts "The key is #{k} and the value is #{v}"
end

Answer 2

您需要创建表值拆分字符串函数来实现这一点。

CREATE FUNCTION [dbo].[fnSplitString] 
( 
    @string NVARCHAR(MAX), 
    @delimiter CHAR(1) 
) 
RETURNS @output TABLE(splitdata NVARCHAR(MAX) 
) 
BEGIN 
    DECLARE @start INT, @end INT 
    SELECT @start = 1, @end = CHARINDEX(@delimiter, @string) 
    WHILE @start < LEN(@string) + 1 BEGIN 
        IF @end = 0  
            SET @end = LEN(@string) + 1

        INSERT INTO @output (splitdata)  
        VALUES(SUBSTRING(@string, @start, @end - @start)) 
        SET @start = @end + 1 
        SET @end = CHARINDEX(@delimiter, @string, @start)

    END 
    RETURN 
END


DECLARE @HotelDes varchar(1000) = 'Wake up to breathtaking views of the iconic Sydney Opera House, the Harbour Bridge or Darling Harbour each morning. You will be spoiled for choice at the Shangri-La Hotel, with a day spa, fitness centre and indoor pool at your disposal.

select splitdata+'.' from [dbo].[fnSplitString] (@HotelDes,'.')
where splitdata like '%'+@HotelCat+'%'

如果您有xml不友好的字符用于交叉应用解决方案，另一种选择是使用反向字符串和charindex

with cte
