Wie zwei Abfragen beitreten?

Question

Ich habe 2 separate Abfragen und möchte join sie und weiß nicht wie. Wenn ich die unten erhalte ich die Fehler laufen:

The used SELECT statements have a different number of columns.

Wie join ich sie erfolgreich?

erste Abfrage

SELECT 

hardware_info.id as ComputerID, 
software_info.OSPlatform as OperatingSystemName, 
software_info.OSVersion as OSVersion, 
agent_info.AgentName as DeviceName, 
hardware_info.last_modified as LastUpdate, 
software_info.AD_MachineOUPath as NTDomainName, 
software_info.AD_UserOUPath as AD_Site, 
hardware_info.ComputerManufacturer as Manufacturer, 
hardware_info.MachineModel as Model, 
hardware_info.CPUCount as NoOfCPUs, 
software_info.OSPlatform as OperatingSystemName, 
hardware_info.MachineSerialno as SerialNumber, 
hardware_info.CPUIDString as CPUDescription, 
hardware_info.CPUSpeed as MaxClockSpeed, 
hardware_info.PrimaryMACAddress as PhysicalAddress, 
hardware_info.PhysicalMemorySize as Memory  

FROM 
agent_info, 
hardware_info, 
software_info, 
machine_tracking_info, 
installed_software_titles  
WHERE 
agent_info.heartbeat_record_id = hardware_info.agent_info_record_id limit 10

**second query** 
SELECT 
enum_value as osplatform 
FROM 
software_info 
INNER JOIN 
    enum_osplatform ON software_info.OSPlatform = enum_osplatform.enum_key 

**SAMPLE RESULT**

Answer 1

Nummernfeld im Schlepptau Abfrage muss gleich sein.

versuchen, wie diese

SELECT 
    hardware_info.id as ComputerID, 
    agent_info.AgentName as DeviceName, 
    hardware_info.last_modified as LastUpdate, 
    software_info.AD_MachineOUPath as NTDomainName, 
    software_info.AD_UserOUPath as AD_Site, 
    hardware_info.ComputerManufacturer as Manufacturer, 
    hardware_info.MachineModel as Model, 
    hardware_info.CPUCount as NoOfCPUs,   
    hardware_info.MachineSerialno as SerialNumber, 
    hardware_info.CPUIDString as CPUDescription, 
    hardware_info.CPUSpeed as MaxClockSpeed, 
    hardware_info.PrimaryMACAddress as PhysicalAddress, 
    hardware_info.PhysicalMemorySize as Memory, 
    software_info.OSVersion , 
    software_info.OSPlatform as OperatingSystemName, 
    null  
FROM 
    agent_info, 
    hardware_info, 
    software_info, 
    machine_tracking_info, 
    installed_software_titles  
WHERE 
    agent_info.heartbeat_record_id = hardware_info.agent_info_record_id 

union 

SELECT 
    null as ComputerID, 
    null as DeviceName, 
    null as LastUpdate, 
    null as NTDomainName, 
    null as AD_Site, 
    null as Manufacturer, 
    null as Model, 
    null as NoOfCPUs,   
    null as SerialNumber, 
    null as CPUDescription, 
    null as MaxClockSpeed, 
    null as PhysicalAddress, 
    null as Memory, 
    null as OSVersion, 
    osplatform ,enum_value 
FROM 
    software_info 
INNER JOIN 
    enum_osplatform ON software_info.OSPlatform = enum_osplatform.enum_key 

Answer 2

Wie oben Sie UNION können und NULL ‚s im zweiten Teil verwenden.

Ich habe es anders angegangen. Füllen Sie einfach den XXX aus, wenn Sie die Informationen bereitstellen.

SELECT 
h.id AS ComputerID, 
a.AgentName AS DeviceName, 
h.last_modified AS LastUpdate, 
s.AD_MachineOUPath AS NTDomainName, 
s.AD_UserOUPath AS AD_Site, 
h.ComputerManufacturer AS Manufacturer, 
h.MachineModel AS Model, 
h.CPUCount AS NoOfCPUs, 
s.OSPlatform AS OperatingSystemName, 
h.MachineSerialno AS SerialNumber, 
h.CPUIDString AS CPUDescription, 
h.CPUSpeed AS MaxClockSpeed, 
h.PrimaryMACAddress AS PhysicalAddress, 
h.PhysicalMemorySize AS Memory, 
s.OSVersion, 
enum_value as OSPlatform 
FROM agent_info a 
INNER JOIN hardware_info h ON a.heartbeat_record_id = h.agent_info_record_id 
INNER JOIN software_info s ON a.heartbeat_record_id = s.agent_info_record_id 
INNER JOIN enum_osplatform e ON s.OSPlatform = e.enum_key
