存儲過程當中拼寫sql並執行

直接上代碼吧，根據不一樣的條件拼寫sql後並執行

ALTER PROCEDURE [dbo].[usp_Statistic_WJB_DZSK_ZT]
(
    @year int,
    @half int,--0表示整年,1表示上半年,2下半年
    @isAll int --0表示只統計黨政幹部人員，1表示統計所有
)
as
declare @sql    nvarchar(4000)

set @sql=N'select id from 
chgrwpj
where id in(select distinct parentid from chgrymd'
if(@isAll=0)
set @sql=@sql + N' where ((unitcode between ''A0000'' and ''A0025'') or (unitcode between ''B0041'' and ''B0044'') or unitcode=''A1206'' or unitcode=''B0003'' or unitcode=''B0017'' or unitcode=''B0034'' or (unitcode=''B0045'' and positionLevel<=6 and positionLevel>0 and positionname<>''驗船師''))'
set @sql=@sql + N') and innerAmount<chgrsh and year(enddate)=@year'
if(@half=1)

set @sql=@sql + N' order by senddate asc'
exec sp_executesql @sql,
