最近開發是遇到sql查詢時，以查詢結果作為列名，也就是動態列查詢，案列如下：
declare @sql varchar(max);
set @sql='select fname 銷售經理,fnumber as 客戶代號 ,
sum(case when 月份 = ''01'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '01') + '],
sum(case when 月份 = ''02'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '02') +'],
sum(case when 月份 = ''03'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '03') +'],
sum(case when 月份 = ''04'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '04') +'],
sum(case when 月份 = ''05'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '05') +'],
sum(case when 月份 = ''06'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '06') +'],
sum(case when 月份 = ''07'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '07') +'],
sum(case when 月份 = ''08'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '08') +'],
sum(case when 月份 = ''09'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '09') +'],
sum(case when 月份 = ''10'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '10') +'],
sum(case when 月份 = ''11'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '11') +'],
sum(case when 月份 = ''12'' then (bordlocal) else 0 end ) as [' + (select top 1 年月 from #orderamount where 月份 = '12') +'],
(case when sum(bordlocal)<0 then 0 else sum(bordlocal) end ) as 接單金額, (case when sum(bordlocal)<0 then 0 else sum(bordlocal) end )* 0.001 as 獎金 from #orderamount t
group by fname,fnumber
order by fname,right(fnumber,2)'
exec(@sql);
執行結果如下：
sql動態查詢
所以我有乙個從網頁傳遞的dict。我想基於dict動態構建查詢。我知道我可以做 session.query myclass filter by web dict 但是，僅當值完全匹配時才起作用。我需要做 像 過濾。我最好的嘗試使用 dict 屬性 for k,v in web dict.items ...
SQL裡動態生成列
一般這種比較複雜一點都用乙個儲存過程來寫比較好。因為單一的檢視不能滿足我們的需求。類似這種，有規律可循的列。如果按照原始的方法 case when then end。我估計是又繁瑣又累，純粹的體力活啊。其實我最開始的時候就是醬寫的 不過好在有大神師傅的指點，簡單多了，而且這個區間值是可以改變的。如下...
