Answer / richa

The PROC SQL step does not require a RUN statement. PROC
SQL executes each query automatically. If you use a RUN
statement with a PROC SQL step, SAS ignores the RUN
statement, executes the statements as usual, and generates
the note shown below in the SAS log:

NOTE: PROC SQL statements are executed immediately;
The RUN statement has no effect.

As per SAS certification guide.

Answer / sandeep

I agree with the above ans and here is little more addition
to the above one is

if you give the run statement SAS ignores the run statement
and executes the query as usual but in editor window you can
see that the query is still running (PROC SQL RUNNING), we
can terminate the proc sql queries with Quit statement only.

like wise in SAS some procedures can be terminated with Run
statements (ex: proc print, proc append) and some procedures
can be terminated with Quit statement only (ex: proc sql).

more views welcome...

Answer / cutepa1

The diff b/n QUIT n RUN is very simple here.... Using a RUN statement one can generate a result for an SQL statement and without terminating the procedure one can continue on the same Procedure with other SQL statements and generate another result using one more RUN statements. This can be done until a QUIT statement is executed or another PROC step or DATA step is initialised ...

Answer / ayetullah

SQL is a non-sas product.WE use RUN statement only with the
SAS codes.Though we can use SQL also and stop the data block
by using QUIT.

Answer / bm

Thank you both for the answers.

But they were basically asking about the internal
processing of QUIT statement. the question was like 'Why
cant SAS recognise RUN as an ending statement in PROC SQL?'.

I heard from someone that PROC SQL is not native to SAS(i
am not very clear by this) and hence a QUIT statement is
required.

any feedback ?

Answer / sandeep

I dont know the exact ans for the what was the internal
process...

here is what I understand is..

some procedures result (output window) can be seen only
using Run statement only... It means we can see the output
only we the procedure is running (so here we use RUN
statement at end of the programme).

where as some procedures result (output window) will be only
after terminating the programme running... so here we use
QUIT statement to terminate the programme. (If we use run
statement the programme is excuted asausual and result is
displayed but the editor window is displayed front of the
output window showing the programme is running)

if anyone know the internal process about this... pls post
the ans.

Answer / dipak

If PROC SQL is ended with Run statement then there will be
no output generated in output window. however if 'Create
table ... as' command is given in proc sql then it will
create the table.

Quit tells SAS to print output to output window, if to be
printed.

how does sas know on which server the piece of code to be executed ? say if a proc olap code is written then how the sas application would detect on which server to execute.
