I Am trying like this but not getting the correct result
select distinct d.Id,g.LOCATION_ID,d.Name,d.SerialNumber,d.ActiveFrom,d.ActiveTo,d.DeviceType,d.DevicePlans,d.VehicleIdentificationNumber,d.LicensePlate,d.LicenseState,d.WorkTime,d.ProductId,d.HardwareId, d.TimeZoneId,tz.TimeZone,d.Groups,d.Comment,d.ImportDate from [adl].[GEOTAB_VEHICLE_INFO_DEVICES] d left join [pbi].[GEOTAB_INFO_GROUPS] g on d.Groups = g.GROUP_ID left join [pbi].[Location_Time_Zone] tz on tz.LocationNumber = g.LOCATION_ID
CodePudding user response:
Select d.*, t.TimeZone
From [adl].[GEOTAB_VEHICLE_INFO_DEVICES] d
Left Join [pbi].[GEOTAB_INFO_GROUPS] g ON g.Group_Id= d.Group_Id
Left Join [pbi].[Location_Time_Zone] t ON g.Location_Id = t.LocationNumber
CodePudding user response:
In SAP ABAP we use this code to use left join :
tables : GEOTAB_VEHICLE_INFO_DEVICES, GEOTAB_VEHICLE_INFO_DEVICES.
