Wählen Sie Zeilen aus 3 Tabellen aus und zeigen Sie sie in 1 Zeile an.

Question

Ich muss aus diesen 3 Tabellen Building, RoomMin und RoomMax auswählen und sie in separaten Feldern darstellen.

Tabellen

GenericTableDataID Building 
17     B1 
18     B1 
20     B1 

RoomMinDataID RoomMin 
17    200 
20    100 

RoomMaxDataID RoomMax 
17    299 
18    399 

Gewünschtes Ergebnis

GenericTableDataID Building RoomMin RoomMax 
17     B1   200  299

Meine obige Abfrage zurückgeben keine Zeilen, weil ich für einen bestimmten suchen bin versucht, Gebäuderaumnummer im inneren WO AUSWÄHLT.

Answer 1

SELECT A.GenericTableDataID, A.Building, B.RoomMin, C.RoomMax 
FROM table_1 AS A 
JOIN table_2 AS B ON 
    A.GenericTableID = B.RoomMinDataID 
JOIN table_3 AS C ON 
    A.GenericTableID = C.RoomMaxDataID 
WHERE A.GenericTableID = 17 

table_1 ist die Top-Tabelle in Ihrer Frage, ist table_2 die Mitte und table_3 ist der Boden.

Answer 2

hier:

select 
    gt.GenericTableDataID, 
    gt.Building, 
    rmn.RoomMin, 
    rmx.RoomMax 
from 
    GenericTable gt, 
    Roommin rmn, 
    Roommax rmx 
where 
    gt.GenericTableDataID = rmn.RoomMinDataID 
    and gt.GenericTableDataID = rmx.RoomMaxDataID 

Answer 3

Try this:

SELECT generic.GenericTableId 
    , Building 
    , RoomMin 
    , RoomMax 
FROM GenericTableDataId generic 
    JOIN RoomMinDataId min_data ON generic.GenericTableDataId = min_data.RoomMinDataId 
    JOIN RoomMaxDataId max_data ON generic.GenericTableDataId = max_data.RoomMaxDataId 

Answer 4

als fellow "gr1zzly BE4R" post, Sie Funktionen JOIN und verwenden Sie ein paar alias

SELECT GenericTableDataID,Building,RoomMin,RoomMax 
From table1 
join table2 on 
    GenericTableDataID=RoomMinDataID 
join table3 on 
    RoomMinDataID=RoomMaxDataID 
where GenericTableDataID = 17 

auch

select GenericTableDataID,Building,RoomMin,RoomMax 
FROM table1,table2,table3 
where GenericTableDataID=RoomMinDataID and RoomMinDataID=RoomMaxDataID and GenericTableDataID=17 

Answer 5

meine letzte Abfrage, eine weitere Option könnte hier:

SELECT DISTINCT Data.GenericTableDataID AS AccessLevelID, TDRR.Building, TDRR.RoomMin, LTDRR.RoomMax, DataF.ValueString AS AccessLevel 
FROM GenericTableData Data 
    INNER JOIN GenericTableDataField DataF ON Data.GenericTableDataID = DataF.GenericTableDataID 
    INNER JOIN GenericTableDefinition Def ON Data.GenericTableDefinitionID = Def.GenericTableDefinitionID 
    INNER JOIN GenericTableDefinitionField DefF ON DataF.GenericTableDefinitionFieldID = DefF.GenericTableDefinitionFieldID AND 
     Def.GenericTableDefinitionID = DefF.GenericTableDefinitionID 
    INNER JOIN TableDataRoomRanges TDRR ON TDRR.BuildingDataID = Data.GenericTableDataID 
WHERE DefF.GenericTableDefinitionFieldID = 13 

-- Query for TableDataRoomRanges view 
SELECT TableDataBuildings.BuildingDataID, TableDataBuildings.Building, TableDataRoomMin.RoomMin, TableDataRoomMax.RoomMax 
FROM 
    TableDataBuildings 
INNER JOIN 
    TableDataRoomMin ON TableDataBuildings.BuildingDataID = TableDataRoomMin.RoomMinDataID 
INNER JOIN 
    TableDataRoomMax ON TableDataBuildings.BuildingDataID = TableDataRoomMax.RoomMaxDataID
