不说语句质量及难易度。。
我想知道大家遇到这钟情况一般怎么处理？？？
是分到不同包含查询语句的函数里面还是像我这样一条语句写出来？？？
这条语句查询出来的都是一个页面上的所以“页签”所包含的内容，最后拼接如下：
SELECT WF_w_pc.XXXX,w_pc_ProjectId,ISNULL(WF_w_pc.w_pc_AnnualPlan,'') w_pc_AnnualPlan,w_pc_ProjectName,Dept_Name,ISNULL(WF_R_BI.YYYYName,'') w_pc_Nature,ISNULL(WF_R_BI2.YYYYName,'') w_pc_SOURCE ,w_pc_StartDate,w_pc_EndDate,ISNULL(WF_w_pc_AP.w_pc_AP_Plan,'') w_pc_AP_Plan
,CASE WF_w_pc.w_pc_Status
WHEN 10 THEN '草稿'
WHEN 20 THEN '审核中'
WHEN 30 THEN '完成'
ELSE '' END
AS w_pc_Status
,w_pc_Backdrop,w_pc_MainContent,w_pc_TechLines,w_pc_ResultForm,w_pc_SocialBenefits,w_pc_EconomicBenefit,w_pc_TechBenefits,w_pc_CooperationForm,w_pc_CooperationByUnit
,ISNULL(WF_w_pc_P.w_pc_P_UserName,'') w_pc_P_UserName
,ISNULL(WF_w_pc_P.proHead,'') proHead
,ISNULL(WF_w_pc_P.proArticipants,'') proArticipants
FROM WF_Research_ProjectCharter WF_w_pc
LEFT JOIN WF_Research_PC_AnnualPlan WF_w_pc_AP
ON WF_w_pc.XXXX=WF_w_pc_AP.XXXX
LEFT JOIN WF_Research_BasicInfo WF_R_BI
