Problem while merging

rishabhmehra13 — Mon, 26 Sep 2016 23:53:32 GMT

i want to join table d.p4 with dig ,Probability is the id

proc sql;
create table p1 as select a.Account_Name as client ,a.Opportunity_Owner as champ,
a.Last_Modified_Date as modified , sum(a.Total_Media_Value) as Tot_Budget,a.Deal_Comments,

b.Total_Media_Value as Digital_bdgt
from d.p3 as a left join dig as b
on a.Probability____= b.Probability____
group by Probability____
order by Probability____ desc;

quit;

log

63 group by Probability____

64 order by Probability____ desc;

ERROR: Ambiguous reference, column Probability____ is in more than one table.

When you joined the data sets, you specified a.Probability___ or b.Probability___. That's the right way to do it.

When you get to GROUP BY or ORDER BY, you have to do the same thing. Pick one. When you just say Probability___, SQL doesn't know which one you mean.

I am still not getting the desired output.
both the data sets have the same values of probability and other columns
too which i require but i want that the output should be all the required
columns of set 1 and only 1 column to be joined to that set 1based on
probability,i dont want repeating probabilities.

proc sql;
create table p1 as select a.Probability____ , a.Account_Name as client
,a.Opportunity_Owner as champ,
a.Last_Modified_Date as modified , sum(a.Total_Media_Value) as
Tot_Budget,a.Deal_Comments,

b.Total_Media_Value as Digital_bdgt
from d.p3 as a left join dig as b
on a.Probability____= b.Probability____
group by a.Probability____
order by a.Probability____ desc;

quit;

If you include variables NOT in your group by clause (or an aggregate function) in your SELECT statement they are considered distinct and are repeated for each row. If you want distinct values add them to your group by or an aggregate function as appropriate.

better display a group of input and its output to show what is wrong

All variables in the select that are not the subject of a summary function need to go into the group by clause.
