SQL查找字符串

Question

我想知道是否可以从另一个表中查找字符串。这有点复杂。

这里的表：（tbl_dishes）

| dish    | Type  | 
| egg, hotdog & bread | Breakfast | 

从上面的表，我想从另一个表获得列盘子的个人描述

第二个表（tbl_Foods）

| food | Description | 
| egg | Fresh  | 
| hotdog | red   | 
| bread | toasted  | 
| steak | meat  | 

假设我的查询是这样的:(但它是错误的）

SELECT food, description FROM tbl_Foods 
    WHERE food Exists IN (SELECT dish FROM tbl_Dishes) 

个

我期望的结果将是：

| food | Description | 
    | egg | Fresh  | 
    | hotdog | red   | 
    | bread | toasted  | 

这就像让在盘中列所有匹配的字。我不知道这是否可能。请帮忙。

谢谢。

Answer 1

SELECT food, description 
FROM tbl_Foods 
join tbl_Dishes 
on tbl_Dishes.dish like ('%' + tbl_Foods.food +'%') 

Answer 2

您将需要拆分列表

DECLARE @DelimString VARCHAR(100) 
SET DelimString = SELECT REPLACE(REPLACE(dish,'&',','),' ', '') FROM tbl_Dishes 

DECLARE @Dish TABLE (Dish VARCHAR(50)); INSERT INTO @Dish SELECT CAST(ParamValue AS VARCHAR) FROM MultiValueParams_String(@DelimString) 

使用此功能。

Create function [dbo].[MultiValueParams_String] (@ParamList varchar(4000)) 
returns @Values table (RoNum INT,ParamValue varchar(4000)) 
as 
begin 
declare @Delim char(1) = ',' -- comma is always the delimiter 
declare @Chrind int = 1 
declare @Piece nvarchar(50) 
declare @RoNum int = 0 
while @Chrind>0 
    begin 
     select @Chrind=charindex(@Delim,@ParamList) 
     if @Chrind>0 
      select @Piece=left(@ParamList,@chrind-1) 
     else 
      select @Piece=@ParamList 
     insert @values(RoNum,ParamValue) values (@RoNum,@Piece) 
     select @ParamList = right(@ParamList,len(@ParamList)-@chrind) 
     if len(@ParamList)=0 break 
     SELECT @RoNum = @RoNum + 1 
    end 
return 
end 

SELECT food, description 
FROM tbl_Foods f 
INNER JOIN @Dish d ON f.food = d.dish 

就像这样。
