Question

I’m getting this error in different places and I have no idea why so I was wondering if anyone here might have any clues. Here’s the sql.

select Intranet.dbo.tblPeople.FirstName,
     Intranet.dbo.tblPeople.LastName,
     Intranet.dbo.tblPeople.CellPhone
     tblActivities.OnSiteSupervisorID,
     tblActivities.OffSiteSupervisorID,
     tblProjects.projectid,
     tblVehicleData.Description AS vehicle,
     tblVehicleData.VehicleID,
    tblVehicleData.ActivityID as ActivityID, 
     tblProjects.ProjectName,
     tblActivities.numPersons,
     tblActivities.Description,
     tblActivities.ChannelNumber,
     tblActivities.StartDate,
     tblActivities.EndDate,
     tblActivities.estimatedExitTime,
     tblLocations.locationname,
from Intranet.dbo.tblPeople,
     smartroadmangement.dbo.tblVehicleData,
     smartroadmangement.dbo.tblProjects,
     smartroadmangement.dbo.tblActivities 
left join smartroadmangement.dbo.tblLocations 
    on smartroadmangement.dbo.tblActivities.locationId = smartroadmangement.dbo.tblLocations.locationid
left join Intranet.dbo.tblPeople as people 
    on people.PersonID = smartroadmangement.dbo.tblActivities.OnSiteSupervisorID
left join tblActivities as Activities 
    on Activities.ActivityID = tblVehicleData.ActivityID
left join tblActivities as Activitiez 
    on Activitiez.ProjectID = tblProjects.ProjectID 
WHERE (smartroadmangement.dbo.tblActivities.StartDate Between '2012-07-15 14:17:09' and '2012-07-15 20:17:09') 
    AND (smartroadmangement.dbo.tblActivities.EndDate Between '2012-07-15 20:17:09'and '2012-07-15 23:17:09')

My first suggestion would be to use proper JOIN syntax on all of your JOINs. You are joining using commas and JOIN syntax which is making is difficult to debug your query.

Your comment stated you are getting the error here:

left join tblActivities as Activities 
    on Activities.ActivityID = tblVehicleData.ActivityID
left join tblActivities as Activitiez 
    on Activitiez.ProjectID = tblProjects.ProjectID

Is that table actually smartroadmangement.dbo.tblActivities in your query?

Based on you comment below, you might want to try:

left join smartroadmangement.dbo.tblActivities as Activities 
    on Activities.ActivityID = tblVehicleData.ActivityID
left join smartroadmangement.dbo.tblActivities as Activitiez 
    on Activitiez.ProjectID = tblProjects.ProjectID

here is a query updated with proper JOIN syntax:

select ppl.FirstName,
     ppl.LastName,
     ppl.CellPhone
     a1.OnSiteSupervisorID,
     a1.OffSiteSupervisorID,
     tblProjects.projectid,
     v.Description AS vehicle,
     v.VehicleID,
     v.ActivityID as ActivityID, 
     tblProjects.ProjectName,
     a1.numPersons,
     a1.Description,
     a1.ChannelNumber,
     a1.StartDate,
     a1.EndDate,
     a1.estimatedExitTime,
     l.locationname,
from Intranet.dbo.tblPeople ppl
left join smartroadmangement.dbo.tblActivities a1
    on ppl.PersonID = a1.OnSiteSupervisorID
left join smartroadmangement.dbo.tblLocations l
    on a1.locationId = l.locationid 
left join smartroadmangement.dbo.tblVehicleData v
    on a1.ActivityID = v.ActivityID
left join smartroadmangement.dbo.tblProjects pj 
    on a1.ProjectID = pj.ProjectID 
WHERE (a1.StartDate Between '2012-07-15 14:17:09' and '2012-07-15 20:17:09') 
    AND (a1.EndDate Between '2012-07-15 20:17:09'and '2012-07-15 23:17:09')
