This is PROC SQL. Could anyone explain what I am getting as output ? Thanks !
proc sql;
select time into :date from end_date;
quit;
In addition to Chris J's answer, the INTO clause has a very versatile functionality. The following resources will give you very good overview.
Essentially using the INTO clause you can create a macro variable which holds a lists of items seperated by a custom delimiter, create a whole host of macro variables inside a single PROC SQL procedure - a task which could take multiple DATA _NULL_ steps & PROC SORT\MEANS\FREQ steps etc...
It is the PROC SQL equivalent of using %let date = <some time value>; or inside a datastep
DATA _NULL_;
set end_date;
call symputx("date", time);
RUN;
Using the Magical Keyword "INTO:" in PROC SQL
SAS(R) 9.2 Macro Language: Reference: INTO Clause
It simply puts the result into a macro variable, in this case the macro variable 'DATE' contains the time value off the record in the dataset end_date.

I have the following problem. We have several streams in Enterprise Miner and we would like to be able to tell how long was each run. I have tried to create a macro that would save the start and end time/date but the problem is that global variables defined in a node, are not seen anymore in a subsequent node (so are global only inside a node, but not between nodes). How people usually solve the problem? Any idea or suggestion?
Thanks, Umberto
Just write out timestamps to log (EM should produce a global log in the same fashion that EG and DI do)
Either use:
data _null_;
datetime = datetime();
put datetime= datetime20.;
run;
or macro language:
%put EM node started at at %sysfunc(time(),timeampm.) on %sysfunc(date(),worddate.).;
with a higly customised message you have read the log in SAS looking for those strings using regex.
Solution 2:
Other option is to created a table in a library that is visible from EM and EG for example and have sql inserts at the beginning/end of your process.
proc sql;
create table EM_logger
(jobcode char(100),
timestamp num informat=datetime20. format=datetime20.);
quit;
proc sql;
insert into EM_logger values('Begining Linear Reg',%sysfunc(datetime()));
quit;
data w;
do i=1 to 10000000;
output;
end;
run;
proc sql;
insert into EM_logger values('End Linear Reg',%sysfunc(datetime()));
quit;
Table layout can be as complex as you want and as long as you can access it you can get your statistics.
Hope it helps
I am trying to use a variable on PROC SQL but i cannot find a proper way through the internet. I just want to apply the following code of T-SQL on PROC SQL:
declare #example as int;
set #example=2;
select * from {table} where {column}=#example;
go
How can i apply this code on PROC SQL?
The translation to SAS SQL is to use a macro variable, the code looks pretty similar, need to wrap it in a PROC SQL block though.
%let example=2;
proc sql;
select *
from table
where variable=&example;
quit;
EDIT: my original reference to the macro variable was incorrect, use an ampersand in SAS not # symbol.
I have a dataset(liste_institution) that contain all the name of the variable that I want to "define" in my proc report statement. Here is my code that work when I call my macro not dynamically(%create_institution(815);). If I use the data statement with the call execute(in comment in my code) it not working. The reason seem to be that when I use the call execute the code is not interpreted in a PROC REPORT that is why it give me error.
proc report data = ventes_all_inst4
missing split = "*" nowd
style(header)=[font_weight=bold background = #339966 foreground = white]
style(column)=[cellwidth=15cm];
%macro create_institution(institution);
define TOTAL_&institution. / display "TOTAL*($)" style(column)=[cellwidth=4cm];
%mend;
/* Give error when I use this data step */
/*data _null_;
set liste_institution;
call execute('%create_institution(' || INS || ');');
run;*/
%create_institution(815);
run;
Is there an easy way to create dynamically define statement in a PROC REPORT from a dataset that contain the column name.
Basically, you have a misunderstanding of how macros work and timing. You need to compile the macro list previous to the proc report, but you can't use call execute because that actually executes code. You need to create a macro variable.
Easiest way to do it is like so:
proc sql;
select cats('%create_institution(',ins,')')
into :inslist separated by ' '
from liste_institution
;
quit;
which makes &inslist which is now the list of institutions (with the macro call).
You also may be able to use across variables to allow this to be easier; what you'd have is one row per ins, with a single variable with that value (which defines the column name) and another single variable with the value that goes in the data table portion. Then SAS will automatically create columns for each across value. Across variables are one of the things that makes proc report extremely powerful.
I am new to SAS and need to sgplot 112 variables. The variable names are all very different and may change over time. How can I call each variable in the statement without having to list all of them?
Here is what I have done so far:
%macro graph(var);
proc sgplot data=monthly;
series x=date y=var;
title 'var';
run;
%mend;
%graph(gdp);
%graph(lbr);
The above code can be a pain since I have to list 112 %graph() lines and then change the names in the future as the variable names change.
Thanks for the help in advance.
List processing is the concept you need to deal with something like this. You can also use BY group processing or in the case of graphing Paneling in some cases to approach this issue.
Create a dataset from a source convenient to you that contains the list of variables. This could be an excel or text file, or it could be created from your data if there's a way to programmatically tell which variables you need.
Then you can use any of a number of methods to produce this:
proc sql;
select cats('%graph(',var,')')
into: graphlist separated by ' '
from yourdata;
quit;
&graphlist
For example.
In your case, you could also generate a vertical dataset with one row per variable, which might be easier to determine which variables are correct:
data citiwk;
set sashelp.citiwk;
var='COM';
val=WSPCA;
output;
var='UTI';
val=WSPUA;
output;
var='INDU';
val=WSPIA;
output;
val=WSPGLT;
var='GOV';
output;
keep val var date;
run;
proc sort data=citiwk;
by var date;
run;
proc sgplot data=citiwk;
by var;
series x=date y=val;
run;
While I hardcoded those four, you could easily create an array and use VNAME() to get the variable name or VLABEL() to get the variable label of each array element.
My company just switched from R to SAS and I am converting a lot of my R code to SAS. I am having a huge issue dynamically declaring variables (macro variables) in SAS.
For example one of my processes needs to take in the mean of a column and then apply it throughout the code in many steps.
%let numm =0;
I have tried the following with my numm variable but both methods do not work and I cannot seem to find anything online.
PROC MEANS DATA = ASSGN3.COMPLETE mean;
#does not work
&numm = VAR MNGPAY;
run;
Proc SQL;
#does not work
&numm =(Select avg(Payment) from CORP.INV);
quit;
I would highly recommend buying a book on SAS or taking a class from SAS Training. SAS Programming II is a good place to start (Programming I if you have not programmed anything else, but that doesn't sound like the case). The code you have shows you need it. It is a complete paradigm shift from R.
That said, try this:
proc sql noprint;
select mean(payment) into :numm from corp.inv;
quit;
%put The mean is: &numm;
Here's the proc summary / data step equivalent:
proc summary data = corp.inv;
var payment;
output out = inv_summary mean=;
run;
data _null_;
set inv_summary;
call symput('numm',payment);
run;
%put The mean is: &numm;
Proc sql is a more compact approach if you just want a simple arithmetic mean, but if you require more complex statistics it makes sense to use proc summary.
