SQL

Question

我一直在处理一份报告，但我不能使用@variable。所以我试图用 "simple" SQL.

来解决我的问题

我的问题是我有一个 table (DEPTH) 包含仓库中的所有位置。但是这个 table 并不能说明该位置是否被占用。要找出答案，我需要在 table (PRODUCTLOCATION)

中使用 "where in" 或 "where not in"

我想将其作为一个输出而不是运行 2 个查询。使用 UNION 我得到了我想要的，但格式错误。

所以 LoationCount 结果应该是 1 列中存在的位置和另一列中不存在的位置

我尝试了很多东西。如您所见，我希望按 EquipmentType 等分组

这是我现在的脚本。

select EquipmentType, EquipmentName, LocationName, LocationCount, Used_Or_UnUsed,  LocationID, LocationType
from 
    (select et.equiptext EquipmentType, 
    e.EQUIPTEXT EquipmentName,
    s.SIZETEXT LocationName, count(*) LocationCount, 'Empty Locations' as Used_Or_UnUsed, s.sizeid LocationID ,
    case when d.LOCATIONTYPE=1 then 'Pick Location' when d.LOCATIONTYPE=2 then 'Buffer Location' else 'Unknown' end as LocationType 
    from depth d with (nolock)
    join SIZEPARAM s with (nolock) on d.SIZEID=s.SIZEID
    join POSITIONS p with (nolock) on d.POSITIONID=p.POSITIONID
    join shelf sh with (nolock) on p.SHELFID=sh.SHELFID
    join EQUIPMENT e with (nolock) on sh.EQUIPID=e.EQUIPID
    join EQUIPMENTTYPE et with (nolock) on e.EQUIPTYPEID=et.EQUIPTYPEID
    where d.DEPTHID not in (select depthid from productlocation) 
    and d.SIZEID in (select SIZEID from SIZEPARAM where SizeCategoryID in (10,20,30,40,50,60,70,210))
    group by et.EQUIPTEXT,e.EQUIPTEXT, d.SIZEid, s.SIZEID, s.SIZETEXT, d.LOCATIONTYPE
    ) t
    group by t.EquipmentType, t.EquipmentName, t.LocationName, t.LocationCount, t.Used_Or_UnUsed, t.LocationID, t.LocationType
union all   
select EquipmentType, EquipmentName, LocationName, LocationCount, Used_Or_UnUsed,  LocationID, LocationType
from 
    (select et.equiptext EquipmentType, 
    e.EQUIPTEXT EquipmentName,
    s.SIZETEXT LocationName, count(*) LocationCount, 'Used Locations' as Used_Or_UnUsed, s.sizeid LocationID ,
    case when d.LOCATIONTYPE=1 then 'Pick Location' when d.LOCATIONTYPE=2 then 'Buffer Location' else 'Unknown' end as LocationType
    from depth d with (nolock)
    join SIZEPARAM s with (nolock) on d.SIZEID=s.SIZEID
    join POSITIONS p with (nolock) on d.POSITIONID=p.POSITIONID
    join shelf sh with (nolock) on p.SHELFID=sh.SHELFID
    join EQUIPMENT e with (nolock) on sh.EQUIPID=e.EQUIPID
    join EQUIPMENTTYPE et with (nolock) on e.EQUIPTYPEID=et.EQUIPTYPEID
    where d.DEPTHID in (select depthid from productlocation) 
    and d.SIZEID in (select SIZEID from SIZEPARAM where SizeCategoryID in (10,20,30,40,50,60,70,210))
    group by et.EQUIPTEXT,e.EQUIPTEXT, d.SIZEid, s.SIZEID, s.SIZETEXT, d.LOCATIONTYPE
    ) t 
    group by t.EquipmentType, t.EquipmentName, t.LocationName, t.LocationCount, t.Used_Or_UnUsed, t.LocationID, t.LocationType
    order by t.EquipmentName asc

请原谅我这个问题的蹩脚格式。

Answer 1

征得您的同意，我不会重复整个查询。并把你需要的精华放在这里。

  SELECT d.depthid AS depthid
        ,CASE WHEN pr.depthid IS NULL THEN 1 END AS not_in_flag
        ,CASE WHEN pr.depthid IS NOT NULL THEN 1 END AS in_flag
    FROM depth d
    LEFT OUTER JOIN productlocation pr
      ON d.depthid = pr.depthid

Answer 2

只需将 d.depthid [not] in (select depthid from productlocation) 从您的 WHERE 子句（它使您只能获得一组或另一组）移动到带有 CASE WHEN 的 select 子句：

select 
  et.equiptext as equipmenttype, 
  e.equiptext as equipmentname,
  s.sizetext as locationname, 
  count(*) as locationcount, 
  case when d.depthid in (select depthid from productlocation) then 'Used Locations' 
       else 'Empty Locations'
  end as used_or_unused, 
  s.sizeid as locationid,
  case when d.locationtype = 1 then 'pick location' 
       when d.locationtype = 2 then 'buffer location' 
       else 'unknown' 
  end as locationtype
from depth d with (nolock)
join sizeparam s with (nolock) on d.sizeid = s.sizeid
join positions p with (nolock) on d.positionid = p.positionid
join shelf sh with (nolock) on p.shelfid = sh.shelfid
join equipment e with (nolock) on sh.equipid = e.equipid
join equipmenttype et with (nolock) on e.equiptypeid = et.equiptypeid
where d.sizeid in (select sizeid from sizeparam where sizecategoryid in (10,20,30,40,50,60,70,210))
group by et.equiptext, e.equiptext, d.sizeid, s.sizeid, s.sizetext, d.locationtype
order by e.equiptext asc

SQL - 其中 "in" 和 "not in" 从同一列到 2 个新列

SQL - Where "in" and "not in" from same column into 2 new columns

select

count

notin
