Hey guys...

I want to have multiple PROC SQL statements to be run based on the value of a variable in a dataset.

e.g. If the value of the 'FLAG' is 1 then i want to run

PROC SQL A

create table example

sel * from example1 where key = FLAG

, if it is 2, then

PROC SQL B

create table example

sel * from example1 where key = FLAG

and so on...

I was planning to have PROC SQL within a data step, is it possible?? else what could be the best possible approach to this problem?

Thanks in advance!!

To propose "the best" approach is kind of hard as you don't really tell us what you have and what you want (have this data / need this output).

Are you eventually only looking for a way to split up a table based on some condition?

data outds0 outds1;

     set example;

     if flag=0 then output outds0;

     else if flag=1 then output outds1;

run;

And another option could be using CALL EXECUTE...

It is possible to use PROC SQL within a DATA step.  Take a look at my South Central SAS User's Group paper from last year:  http://www.scsug.org/SCSUGProceedings/2011/poling1/SQL%20Function.pdf.  While the code presented in the paper only executes a SELECT statement, I think that you could modify the code to execute a CREATE TABLE statement.
