Hi All,
I am using SAS 9.4 and have two SAS datafiles in which there are observations with the identifier, customer ID, listed as 'custID'.
The first file, "HairColor" has the following layout:
custID sex HairCol
1 M Black
2 F Brown
3 F Brown
4 M Red
10 M Black
The second file, "VisitCost" has the following layout:
custID VisDate Cost Sex
2 12/01/10 150 F
4 12/15/10 180 M
4 12/28/10 210 F
7 12/28/10 140 F
9 12/31/10 500 M
10 01/05/11 200 F
I would like to be able to delete the observations in the "VisitCost" file that don't have a corresponding CustID in the "HairCol" file. Thus, the resulting dataset, "VisitCost2" would look like this:
custID VisDate Cost Sex
2 12/01/10 150 F
4 12/15/10 180 M
4 12/28/10 210 F
10 01/05/11 200 F
Any help would be much appreciated!
To delete without creating a new dataset:
proc sql;
delete from VisitCost
where custId not in (select custId from HairColor);
quit;
