7.  Why D?  I think A and D are both wrong.

Which one of the following programs contains a syntax error?

A.      proc sql;

select product.*, cost.unitcost, sales.quantity

from product p, cost c, sale s

where p.item = c.item and p.item = s.item;

quit;

B.      proc sql;

select product.*, cost.unitcost, sales.quantity

from product , cost , sale

where product.item = cost.item and product.item = sales.item;

quit;

C.      proc sql;

select p.*, cost.unitcost, sales.quantity

from product as p , cost as c , sale as s

where p.item = c.item and p.item = s.item;

quit;

D.      proc sql;

select p.*, cost.unitcost, sales.quantity

from product , cost , sale

where product.item = cost.item and product.item = sales.item;

quit;

14. Why D?

Consider the following SAS log:

229 data sasuser.ranch sasuser.condo / view = sasuser.ranch;

230 set sasuser.houses;

231 if style='RANCH' then output sauser.ranch;

232 else if style='CONDO' then output sasuser.condo;

233 run;

NOTE: DATA STEP view saved on file SASUSER.RANCH. NOTE:

A stored DATA STEP view cannot run under a different operating system.

234 235 proc print data = sasuser.condo;

ERROR: File sasuser.condo data does not exist.

236 run;

NOTE: The SAS system stopped processing this step because of errors.

Which one of the following explains why the PRINT procedure fails?

A. sasuser.condo is a stored DATA STEP program.

B. A SAS data file and SAS data view cannot be created in the same DATA STEP.

C. A second VIEW= sasuser.condo OPTION was omitted on the DATA statement.

D. The view sasuser.ranch must be processed before sasuser.condo is created.

[size=14.6667px]21. Why D not C?

[size=14.6667px]The following SAS program is submitted:

[size=14.6667px]%let lib = %upcase (sasuser);

[size=14.6667px]pro sql;

[size=14.6667px]select nvar from dictonary.tables

[size=14.6667px]where libname = "&lib";

[size=14.6667px]quit;

[size=14.6667px]Given that several SAS data sets exist in the SASUSER library, which one of the following is generated as output?

[size=14.6667px]A.      no result set

[size=14.6667px]B.      a syntax error in the log

[size=14.6667px]C.      a report showing the names of each table in SASUSER

[size=14.6667px]D.      a report showing the number of columns in each table in SASUSER
