Hello all,

I would be happy to get your guidance in the following query.

I have two data sets- Data1 and Data2 and I need Dataset called data3 as shown below

Data1- Looks like Data2-Looks like Data3- Output required

Var1 (Num) Var2 (Char) (it is blank) Var1 (Num) Var2 (Char) Var1 (Num) Var2 (Char)

1 Blank 1 green 1 green

1 Blank 2 Red 1 green

1 3 Orange 1 green

2 4 White 2 Red

2 2 Red

2 .

3 3 Orange and for 4 White and so on.

3 I used the following- after sorting-----data data3; merge data1 (in=a) data2 (in=b); by var1; if a; run;

Please guide me

Thank you

Problem is the existence of VAR2 on your 'many' table. Since it reads only one record from the 'few' table only the first value will be replaced. Easiest solution is to DROP or RENAME the variable.

data data3;

merge data1 (in=in1 drop=var2) data2 (in=in2);

by var1;

if in1;

run;

Try this:

Data Data1;

INPUT VAR1;

VAR2=' ';

cards;

;

RUN;

DATA Data2;

LENGTH VAR1 8 VAR2 $ 8;

INPUT VAR1 VAR2;

CARDS;

1 green

2 Red

3 Orange

4 White

;

RUN;

data data3;

merge data1 (keep=var1) data2;

by var1;

run;
