Given the SAS data sets:
WORK.EMPLOYEE WORK.NEWEMPLOYEE
Name Dept Names Salary
-------- ----- -------- ------
Alan Sales Michelle 50000
Michelle Sales Paresh 60000
A SAS program is submitted and
the following is written to the SAS log:
101 proc sql;
102 select dept, name
103 from WORK.EMPLOYEE
104 where name=(select names
from newemployee
where salary > 40000)
ERROR: Subquery evaluated to more than one row.
105 ;
106 quit;
What would allow the program to
successfully execute without errors?
A.
Replace the where clause with:
where EMPLOYEE.Name=(select Names delimited with ','
from WORK.NEWEMPLOYEE
where Salary > 40000);
B.
Replace line 104 with:
where EMPLOYEE.Name =ANY (select Names separated with ','
from WORK.NEWEMPLOYEE
where Salary > 40000);
C.
Replace the equal sign with the IN operator.
D.
Qualify the column names with the table names.
Answer:(C)
I am wondering why (B) is not correct. Any thoughts? Thanks a lot.
