請教這段sql語法是錯在哪裡?

Question

怎麼欄位的它牌會消失了?
語法哪裡錯了?

 select g.維修人員,g.接單數,g.保固內,g.保固外,h.它牌 from (
 select e.維修人員,e.接單數,e.保固內,f.保固外 from (
 select c. 維修人員,c.接單數,d.保固內 from (
 select a.維修人員 維修人員,b.接單數 from (
    
	select distinct wo.MECHANIC_NAME 維修人員 from WO
    group by MECHANIC_NAME

    )a Left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(*) 接單數 from  WO
     group by wo.MECHANIC_NAME
    )b ON (A.維修人員 = b.維修人員)

--需確認 ASSET.HAVEWARRANTY=1 (保內還是外)
    )c left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(ASSET.HAVEWARRANTY) 保固內 from ASSET
     join wo on (wo.ASSET_ID = ASSET.ASSET_ID)
     where ASSET.HAVEWARRANTY = 1
     group by wo.MECHANIC_NAME
    )d on (c.維修人員 = d.維修人員)

    )e left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(ASSET.HAVEWARRANTY) 保固外 from ASSET
     join wo on (wo.ASSET_ID = ASSET.ASSET_ID)
     where ASSET.HAVEWARRANTY = 0
     group by wo.MECHANIC_NAME
    )f on (e.維修人員 = f.維修人員)

	)g left join( --它牌
		 select wo.MECHANIC_NAME 維修人員,count(ASSET.BRAND_NAME) 它牌 from ASSET
         join wo on (wo.ASSET_ID = ASSET.ASSET_ID) 
         where (ASSET.BRAND_NAME NOT IN ('brother', 'NCC'))
		 group by wo.MECHANIC_NAME
	)h on (g.維修人員 = h.維修人員)

這裡欄位它牌
下面再加一段sql指令它牌欄位就不見了

select i.維修人員,i.接單數,i.保固內,i.保固外,j.已完修數 from (
 select g.維修人員,g.接單數,g.保固內,g.保固外,h.它牌 from (
 select e.維修人員,e.接單數,e.保固內,f.保固外 from (
 select c. 維修人員,c.接單數,d.保固內 from (
 select a.維修人員 維修人員,b.接單數 from (
    
	select distinct wo.MECHANIC_NAME 維修人員 from WO
    group by MECHANIC_NAME

    )a Left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(*) 接單數 from  WO
     group by wo.MECHANIC_NAME
    )b ON (A.維修人員 = b.維修人員)

--需確認 ASSET.HAVEWARRANTY=1 (保內還是外)
    )c left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(ASSET.HAVEWARRANTY) 保固內 from ASSET
     join wo on (wo.ASSET_ID = ASSET.ASSET_ID)
     where ASSET.HAVEWARRANTY = 1
     group by wo.MECHANIC_NAME
    )d on (c.維修人員 = d.維修人員)

    )e left join (
     select distinct wo.MECHANIC_NAME 維修人員,count(ASSET.HAVEWARRANTY) 保固外 from ASSET
     join wo on (wo.ASSET_ID = ASSET.ASSET_ID)
     where ASSET.HAVEWARRANTY = 0
     group by wo.MECHANIC_NAME
    )f on (e.維修人員 = f.維修人員)

	)g left join( --它牌
		 select wo.MECHANIC_NAME 維修人員,count(ASSET.BRAND_NAME) 它牌 from ASSET
         join wo on (wo.ASSET_ID = ASSET.ASSET_ID) 
         where (ASSET.BRAND_NAME NOT IN ('brother', 'NCC'))
		 group by wo.MECHANIC_NAME
	)h on (g.維修人員 = h.維修人員)
	 
	)i left join ( 
       select wo.MECHANIC_NAME 維修人員,count(wo.STATE_NAME) 已完修數 from WO
	   where wo.STATE_NAME  like N'%已完修%'
       group by MECHANIC_NAME
    )j on (i.維修人員 = j.維修人員)

麻煩各位大神語法錯在哪?

Answer 1

select i.維修人員,i.接單數,i.保固內,i.保固外,j.已完修數 ,??? from (
 select g.維修人員,g.接單數,g.保固內,g.保固外,h.它牌 from (
是不是最後SELECT缺了它牌?
