How would you code a merge that will keep only the observations that have matches from both sets.

Accenture, Bank Of America,

How would you code a merge that will write the matches of both to one data set, the non-matches from the left-most data set to a second data set, and the non-matches of the right-most data set to a third data set.

Accenture,

What is the Program Data Vector (PDV)? What are its functions?

Accenture,

Does SAS ‘Translate’ (compile) or does it ‘Interpret’? Explain.

Accenture,

At compile time when a SAS data set is read, what items are created?

Accenture,

Name statements that are recognized at compile time only?

Accenture,

Identify statements whose placement in the DATA step is critical.

Accenture,

How could you generate test data with no input data?

CTS,

How do you debug and test your SAS programs? What can you learn from the SAS log when debugging? How do you test for missing values? How would you create multiple observations from a single observation? What are some good SAS programming practices for processing very large data sets? Briefly describe 5 ways to do a "table lookup" in SAS. Why is SAS considered self-documenting? Are you sensitive to code walk-throughs, peer review, or QC review? What other SAS features do you use for error trapping and data validation? How does SAS handle missing values in: assignment statements, functions, a merge, an update, sort order, formats, PROCs?

WHAT DIFFERRENCE DID YOU FIND AMONG VERSION 6 8 AND 9 OF SAS.

Genzyme,

Hello, I have PROC SQLs results group by 3 fields and I use SUM and COUNT functions in SQL. The problem is when I try to display my result with PROC TABULATE. I am getting very big numbers. I believe I make a mistake some where in Tabulate. Here is my Proc Tabulate. PROC TABULATE DATA=OUT04_05 FORMAT=12.; CLASS YR CENTRE VISA / PRELOADFMT EXCLUSIVE; VAR NEWUSER FRAUD TRANSFER AUTUSER REISSUE; TABLE CENTRE ALL, (YR ALL)*VISA, (NEWUSER*F=COMMA12. AUTUSER*F=COMMA12. FRAUD*F=COMMA12. TRANSFER*F=COMMA12. REISSUE*F=COMMA12.) / MISSTEXT={LABEL='0'} PRINTMISS RTS=20; FORMAT VISA VISAFMT.; KEYLABEL SUM = ' ' ALL = 'TOTAL'; LABEL YR = 'DATE YEAR' NEWUSER = 'TOTAL NEW ACCT' TRANSFER = 'TOTAL TRANSFER' FRAUD = 'TOTAL FRAUD TRANSFER' AUTUSER = 'TOTAL AUTH USERS' REISSUE = 'TOTAL REISSUE'; When I code it like : NEWUSER*N*F=COMMA12. AUTUSER*N*F=COMMA12. I get same amount numbers but to find a NEWUSER I use COUNT(*) and to find AUTUSER I use SUM(xxxx) function so both result shouldn’t be the same my problem is in this point. Could you tell me where the problem in code is. How can I display my result? TX.
