Join statement is causing too many results...

I have a select statement that is joining to tables.

In the ConsolidatedBOLReports Table there is 1 record per ConsolidatedProNumber.  In the conbol table there is multiple records per consolidatedProNumber.  

I am using this query to show the report from the consolidatedbolreports table but it is returning 8 rows when I only want it to return 1.  I know it is returning multiple rows because the join is causing it to return a row for each record in the joining table which in this case is conbol.  How can I get it to only return 1 row?

Thanks.
select r.id,r.consolidatedpronumber,r.PlantId,r.carrier, c.tocompany as ShipToCompany, c.toaddr1 as ShipToAdd1,
c.tostate as ShipToState,c.tocity as ShipToCity,c.tozip as ShipToZipCode,c.conbolid as ConBol    
from consolidatedbolreports r join conbol c 
on r.consolidatedpronumber = c.conproid and r.Carrier=c.Carrier    
where consolidatedpronumber in (select conproid from conbol ) 
and r.consolidatedpronumber='123456' and r.PlantId='PLANT001' and r.carrier='Conway'

did you try using distinct
select distinct r.id,r.consolidatedpronumber,r.PlantId,r.carrier, c.tocompany as ShipToCompany, c.toaddr1 as ShipToAdd1,
c.tostate as ShipToState,c.tocity as ShipToCity,c.tozip as ShipToZipCode,c.conbolid as ConBol    
from consolidatedbolreports r join conbol c 
on r.consolidatedpronumber = c.conproid and r.Carrier=c.Carrier    
where consolidatedpronumber in (select conproid from conbol ) 
and r.consolidatedpronumber='123456' and r.PlantId='PLANT001' and r.carrier='Conway'

Obviously since it is returning 8 records, there is different data in the conbol table.

You can try this if it works in your situation ... select distinct r.id, r.consolidatepronumber ...

If the data c.tocompany, c.toaddr1, c.tostate1, c.tocity, c.tozip, c.conbolid is the same for all the 8 records, then it will work.

If not, you'll need to decide which record you want to select.

Come back to the forum and let us know if you need more help.
