Question

问题：

我想将一个值@Test传递给存储过程，我知道当@Test是某些值时，一切都很好。但是，我希望在一个@Test值下过滤Table / Gridview中的几个值。

即。用户搜索＆＃34; Red＆＃34;我想展示＆＃34; Red＆＃34; ＆＃34;粉红＆＃34;等...

我确信必须有一些例子，但我已经搜索过但没找到它们。我尝试了BEGIN和IF语句。

如果.net我会添加一个If @Text =＆＃39; Pink＆＃39;然后 sql = sql＆amp; ......陈述......

到目前为止，我有......

SELECT * FROM TblColours
WHERE 

Room LIKE  '%' + @sRoom + '%'   
or Colours LIKE  '%' + @sColours  + '%' 

IF @sColours  = 'Pink'
or Colours = 'Red'
or Colours = 'Shade of Pink'

END

我同意Andrew的观点，将颜色及其分组存储在单独的表中要容易得多 - 它可能看起来像下面的那样（使用了两个新表，＃Colours和#Colourgroup）。

-- SETUP TABLES AND VALUES
----------------------------------------------------------------------------------------------
IF OBJECT_ID('tempdb.dbo.#Colours') IS NOT NULL DROP TABLE #Colours
IF OBJECT_ID('tempdb.dbo.#TblColours') IS NOT NULL DROP TABLE #TblColours
IF OBJECT_ID('tempdb..#ColourGroups') IS NOT NULL DROP TABLE #ColourGroups

CREATE TABLE #Colours
( Id        INT         NOT NULL PRIMARY KEY CLUSTERED
 ,GroupId   INT         NOT NULL
 ,Name      VARCHAR(50) NOT NULL)

CREATE TABLE #ColourGroups
( Id    INT         NOT NULL PRIMARY KEY CLUSTERED
 ,Name  VARCHAR(50) NOT NULL)

CREATE TABLE #TblColours
( Room      VARCHAR(50) NOT NULL
 ,ColourId  INT         NOT NULL)

INSERT #Colours
    SELECT * FROM
        (SELECT 1 AS Id, 1 AS GroupId, 'Red'        AS Name UNION
         SELECT 2 AS Id, 2 AS GroupId, 'Orange'     AS Name UNION
         SELECT 3 AS Id, 3 AS GroupId, 'Yellow'     AS Name UNION
         SELECT 4 AS Id, 1 AS GroupId, 'Pink'       AS Name UNION
         SELECT 5 AS Id, 1 AS GroupId, 'Scarlet'    AS Name UNION
         SELECT 6 AS Id, 1 AS GroupId, 'Rose'       AS Name)        AS SomeRandomColours
    ORDER BY Id

INSERT #ColourGroups
    SELECT * FROM 
        (SELECT 1 AS Id, 'Red'      AS Name UNION
         SELECT 2 AS Id, 'Orange'   AS Name UNION
         SELECT 3 AS Id, 'Yellow'   AS Name)        AS SomePossibleGroups
    ORDER BY Id

INSERT #TblColours Values ('Gail''s Bedroom', 6)
INSERT #TblColours Values ('The Horrid Bathroom', 2)
INSERT #TblColours Values ('The Main DrawingRoom', 5)
INSERT #TblColours Values ('Paul and Barbara''s Bedroom', 4)
INSERT #TblColours Values ('Paul''s Study', 1)

-- Include Derived colour working back from the group if you want to find all the colours in
-- the same group as your search.
DECLARE
     @sRoom     VARCHAR(50) = 'Barbara'
    ,@sColours  VARCHAR(50) = 'Pink'

SELECT DISTINCT
     Room.Room
    ,Colour.Name

FROM        #TblColours     AS Room
INNER JOIN  #Colours        AS Colour           ON Room.ColourId = Colour.Id
INNER JOIN  #ColourGroups   AS ColourGroup      ON Colour.GroupId = ColourGroup.Id
INNER JOIN #Colours         AS DerivedColour    ON ColourGroup.Id = DerivedColour.GroupId
WHERE 
    Room LIKE  '%' + @sRoom + '%'   
OR Colour.Name = @sColours
OR ColourGroup.Name = @sColours
OR DerivedColour.Name = @sColours

SQL存储过程添加到语句
