Hi, all
I want to merge to datasets
data1 has VAR1 VAR2 VAR3 year
data2 has VAR1 VAR2 VAR4 VAR 5 year
I use proc sql left join data1 with data2 with the following conditions :
data1.var1=data2.var1
1993<year<2000
i got error using the code below:
proc sql;
create table WANT as select
A.*, B.*
From DATA1 as A left join DATA2 as B
WHERE 1993<=YEAR<=2000
On A.VAR1 =B.VAR2
order by VAR1, year;
quit;
please help and Thanks!

Let me try to guess and at least give you a starting point :
proc sql;
create table WANT as select
A.*, B.VAR4, B.VAR5
From DATA1 as A left join DATA2 as B
on A.VAR1=B.VAR1 and A.VAR2=B.VAR2 and A.year=B.year
WHERE A.year between 1993 and 2000
order by VAR1, year;
select * from WANT;
quit;

Which of the two YEAR variables do you want to subset on?
Perhaps you want to add the condition that A.year = B.year ?
Since you are doing a LEFT JOIN perhaps you want to subset on A.year ? Or perhaps both?
Let me try to guess and at least give you a starting point :
proc sql;
create table WANT as select
A.*, B.VAR4, B.VAR5
From DATA1 as A left join DATA2 as B
on A.VAR1=B.VAR1 and A.VAR2=B.VAR2 and A.year=B.year
WHERE A.year between 1993 and 2000
order by VAR1, year;
select * from WANT;
quit;
