我有一個存儲過程，獲取項目列表，排序和應用分頁。
但是我也需要添加過濾。因此，我想要做的是通過在過濾器 像「27 =‘有些公司’; 32 ='奧克蘭」的字符串，並將其分割成一個臨時表（見下文分裂代碼）如何將動態過濾器傳遞到存儲過程與分頁
建議拆分代碼
CREATE TABLE #Filters
(
ModelEntityId int not null,
ValueText nvarchar(max)
)
WHILE (@pos <> 0)
BEGIN
SET @NextFilter = substring(@Filters,1,@Pos - 1)
SET @SubPos = charindex('=',@NextFilter)
insert into #Filters (ModelEntityId, ValueText)
Values (substring(@NextFilter, 1, @SubPos-1),
substring(@NextFilter,@subPos+1, len(@NextFilter)))
SET @Filters = substring(@Filters,@pos+1,len(@Filters))
SET @pos = charindex('~',@Filters)
END
我的數據存儲在一個非常通用的方式，使一個「記錄」可能是這樣的
ContainerModelEntityId DataContainerId ModelEntityId ValueText
4 17 5 'sunshine company'
4 17 6 '12999'
4 17 7 '01/12/2010'
...
4 18 5 'moonlight company...
- ContainerModelEntityId在容器類型（即企業，個人等）
- DataContainerId是「行」
- ModelEntityId是「田」
- ValueText是實際值
目前下方的SP有傳遞到成SortFieldId它可以說，這是一個5，然後我在我的數據表上進行連接，並對ModelEntityId = 5進行排序。但是現在我也想對我的#filter表中的值進行連接，並且只返回結果值匹配（我已經在下面的代碼中發表了評論，以顯示我認爲邏輯應該去的地方）。但在這一點上，我已經打消了我的想法，因爲設定的邏輯通常會讓我頭疼。任何幫助讚賞。
