combining two dataset different format

[monday89]

I have two dataset with different variable formats

dataset #1

reasons	group1	group2
reason1	1 (6%)	10 (48%)
reason2	4 (22%)	7 (33%)
reason3	6 (33%)	1 (5%)
reason4	7 (39%)	3 (14%)

group1 and group2 format are both $22.;

dataset2;

reasons	group1	group2
TOTAL	18	21

group1 and group2 are best12.;

i want to combine using UNION both tables to this:

reasons	group1	group2
reason1	1 (6%)	10 (48%)
reason2	4 (22%)	7 (33%)
reason3	6 (33%)	1 (5%)
reason4	7 (39%)	3 (14%)
TOTAL	18	21

I did:

proc sql; 

create table want_merge as

select  * from dataset1

union all

select * from dataset2;

quit;

I am getting error "group 1 has been defined as both character and numeric' . i changed the format in each dataset to 22.; but still not work

We'd need to see your actual SAS data sets, and how they were created. What you have shown us is not a SAS data set, it is an output from a PROC, and non-informative.

In any event, in the creation of data set #1 and data set #2, somehow you have created group1 as numeric in one and group1 as character in the other, and that has to be fixed so they are both character, or both numeric.

Yes, I understand. Dataset1 is derived dataset for calculations and dataset2 is the denominator. 

dataset1
Variable	Type	Len	Label
reasons	Char	1000
group1	Char	22
group2	Char	22

dataset2
Variable	Type	Len	Label
reasons	Char	5
group1	Num	8
group2	Num	8

I am trying forcing all variables to be character format. Not so much worried about what is in it. THANK YOU

So you have to create these data sets differently, so that group1 is numeric in both (or character in both); and the same for group2.
