Question

PROC SQL stops running when it encounters which of the following?

a. Semicolon
b. FROM clause
c. RUN statement
d. QUIT statement
e. A second SELECT statement

Answer 1

The QUIT statement causes PROC SQL to stop running in SAS by terminating the procedure. Other options listed do not end PROC SQL's execution.

Step-by-step explanation:

The student asked which statement causes PROC SQL in SAS to stop running. The correct answer is d. QUIT statement. In SAS, the QUIT statement is used to end a PROC SQL step. The presence of a semicolon by itself does not stop the execution of PROC SQL, as semicolons in SAS are used to signify the end of a statement within the procedure

Similarly, the FROM clause is part of the syntax within a SELECT statement, and the RUN statement is used to execute the statements within PROC SQL but does not end its execution. A second SELECT statement is simply part of the continued PROC SQL code. Thus, it is the QUIT statement that signifies the completion of all PROC SQL code and instructs SAS to terminate the PROC SQL procedure.
