join tables with "lag"

usuario_estudo — Tue, 04 Jun 2019 20:46:52 GMT

Hello,

Please, can anybody help me?

I need to join two tables (TABLE 1 and TABLE 20 to get TABLE 3, as I explain and exemplify it in the attached excel.) Can you help me, because I am not able to create this code.

I need to do this in SAS in sql, for a number of variables and a larger amount of values. What I send in excel is just one example.

Hello,

Here is the solution

data table1;
input CART $	INI_3	MED_1	FIN_2;
datalines;
A 1.50 2.90 4.30
B 1.30 2.40 4.80
;
run;

data table2;
input REF	INI	MED	FIN;
datalines;
1 1.44 9.50 5.76
2 3.70 7.80 6.80
3 5.96 6.10 7.84
4 8.22 4.40 8.88
5 10.48 2.70 9.92
6 12.74 1.00 10.96
7 4.70 6.98 11.00
8 17.26 12.96 11.04
9 29.82 18.94 11.08
10 42.38 24.92 11.12
;
run;

proc sql;
create table test as
select a.*,b.* from table1 as a , table2 as b;

proc sql;
create table &finaldata as
select cart,sum(output1) as output from

PROC SQL;
SELECT MEMNAME INTO :DATASETNAME SEPARATED  BY ' ' FROM DICTIONARY.TABLES WHERE LIBNAME='WORK' AND MEMNAME LIKE '_W%';
