hello
we use (select data.*) to choose those variables we want, but how can we do a selection to choose all variables but to exclude just one variable?
This question came up when i tried to merge two datasets by "id", but I got a warning msg said the "id" had already existed.
Then I have to manually rewrite the 'select' statement.
Any suggestion ? Thanks! se
That would work better using a RENAME dataset option.
create table want(drop=x) as
select a.*,b.*
from data1 a
, data2(rename=(id=x)) b
where a.id = b.x
;
I think there might be an option to turn off that warning but I don't recall.
One other method is to run it with the feedback option:
proc sql feedback;
create table want as
select *
from sashelp.class;
quit;
Get the list from the log and then delete the one(s) you don't want.
You can rename it ,then drop it at the output datasets.
proc sql;
create table want(drop=x) as
select a.* , b.b1,b.b2,...., b.id as x
That would work better using a RENAME dataset option.
create table want(drop=x) as
select a.*,b.*
from data1 a
, data2(rename=(id=x)) b
where a.id = b.x
;
