How can I read in .SQL files and have them run within SAS?

[InspectahDex]

A colleague of mine does not uses SAS but uses R and SQL Server Management Studio. I need to collaborate with him to write SQL code but we were wondering if there was a way to import .SQL code (queries) into a SAS program and have them run within SAS. I couldn't find anything online but it seems like the only option is to copy and paste each SQL file separately into a SAS Program. Is there a better way to do this so SAS can run and write to a .SQL file?

You can import sql files: 

data _null_; 
  file "&wdir\t.sql";
  put 'select * from sashelp.class;';
run;
options source2;
proc sql;
  %include "&wdir\t.sql";
quit;

Running the file as pass-through SQL would be trickier.

Maybe something like:

data _null_; 
  file "&wdir\t-sql.sql";
  put ' * from [dbo].[tab1]' ;
run;
options source2;
proc sql;  
  connect using SQLSVR;
  select * from connection to SQLSVR(
    select
    %include "&wdir\t-sql.sql" ;
    order by AGE
  );
quit;

Hi,

I have a task where I need to read multiple texts files containing SQLs from a shared location on SAS studio and dump/export the output to a folder in SAS only. 

I am able to pick, read and run one .text file containing a SQL and export that to a folder. But how do I do if I have like 10 .text files present in the input location. Please help on this. 

data _null_; *reading the SQL script into a variable, hopefully under 32767?;
infile "/dslanalytics-shared/dgupt12/SQLs/Query.txt" recfm=f lrecl=32767 pad;
input @1 sqlcode $32767.;
call symputx('sqlcode',sqlcode); *putting it into a macro variable;
run;

proc sql;
connect to odbc as mycon (complete="DRIVER={SnowflakeDSIIDriver};
SERVER=;
UID=&usr.;
PWD=&pwd.;
WAREHOUSE=;
DATABASE=;
SCHEMA=;
dbcommit=10000 autocommit=no
readbuff=200 insertbuff=200;");

create table final_export as
select * from connection to mycon(&sqlcode.);
disconnect from mycon;
quit;

proc export data = work.final_export
outfile = "/dslanalytics-shared/dgupt12/Report/final_report.csv"
DBMS = csv REPLACE;
run;

The way you are doing it is complicated and also macro variables are limited to a length of 32K. Using @ChrisNZ 's %INCLUDE approach is way better:

%macro Run_SQL (SQL_File = , CSV_File = );

proc sql;
connect to odbc as mycon (complete="DRIVER={SnowflakeDSIIDriver};
SERVER=;
UID=&usr.;
PWD=&pwd.;
WAREHOUSE=;
DATABASE=;
SCHEMA=;
dbcommit=10000 autocommit=no
readbuff=200 insertbuff=200;");

create table final_export as
select * from connection to mycon(
%include "/dslanalytics-shared/dgupt12/SQLs/&SQL_File.";
);
disconnect from mycon;
quit;

proc export data = work.final_export
outfile = "/dslanalytics-shared/dgupt12/Report/&CSV_File."
DBMS = csv REPLACE;
run;

%mend Run_SQL;

%Run_SQL (SQL_File = Query1.txt, CSV_File = final_report1.csv);
%Run_SQL (SQL_File = Query2.txt, CSV_File = final_report2.csv);

@SASKiwi Thank you very much for the approach. This seems very easy from the one I am using.

But I am getting the below error while running the below code for the %Include statement. (File attached). I have executed the code as it is as you had shared. I have just updated the connection details to run. Was anything else needed to be changed?

And the output part which you have mentioned will have to written for each file, how do I get it to work dynamically which takes the name of the text file from the input location and generate output file with the same name?

Any help on this will be very much appreciated. I am new to SAS stuck with this task now.

Do not attach files to share error messages.  Just copy the text and paste it into the pop-up window you get when you click on the Insert Code icon.

If you must post a photo then just paste it in or use the Insert Photos icon.

I cannot see the files because the site the SAS communities uses is blocked by my company.  Here is what your DOCX file looks like when I attempt to view it using the link the forum creates.

@Tom Sorry, about that. I am getting this error when the code is taking the input files for processing. I hope it helps now.

It does not really work to try to invoke %INCLUDE in the MIDDLE of a statement.

Try copying the original file into another file with the extra code before and after it.

I don't have access to T-SQL but lets just do an example with a normal SAS SQL query instead.

So first create a file with the query. Let's call that file SQLCODE .

Then copy that into a file name WANT that adds some text before and after it.

Then use %INCLUDE to run it.

filename sqlcode temp;
data _null_; 
  file sqlcode ;
  put ' select * from sashelp.class ' ;
run;

filename want temp;

data _null_;
  infile sqlcode end=eof;
  file want;
  if _n_=1 then put 'create table class as (' ;
  input;
  put _infile_;
  if eof then put ');' ;
run;

proc sql;
%include want / source2;
quit;

Results:

2346  filename sqlcode temp;
2347  data _null_;
2348    file sqlcode ;
2349    put ' select * from sashelp.class ' ;
2350  run;
