Selection of the previous date and comparison of the result with the current one

Gieorgie — Fri, 19 Nov 2021 10:26:15 GMT

I have this problem because I have a promt set for which picks the report date for me, I select it with where in proc sql. However, it also needs to create a table where I will compare with the previous last date. What function to use for this?

%let gv_date_dly=%sysevalf(%bquote('&date_dly.'d));

this is the code for selecting the actual results,

proc sql;
create table zabcheck as
select 
sum(zab_hip) as hip_curr
,zab_data_spr as date_curr
from _mart.zab_kred 
where zab_data_spr=&gv_date_dly. and zab_hip = 1
group by zab_data_spr
;
quit;

And i would like to create table where

where zab_data_spr=&gv_date_dly. will be for previous date ( always last day of month)

So you have a macro variable with a date in DATE9. format, and need another macro variable that contains the raw value of the last day of the previous month from that?

Exactly, every day of the report until the last day of the month.

%let date_dly = 15nov2021;

%let gv_date_dl = %sysfunc(intnx(month,%sysevalf("&date_dly."d),-1,e));

%put &=gv_date_dl;

%put %sysfunc(putn(&gv_date_dl.,yymmdd10.));

The last two statements are for control purposes only.
