Why cannot I merge these two tables?

Mirisage — Sun, 16 Sep 2012 17:10:11 GMT

Hi SAS Forum,

I have been trying to merge the attahced two tables for hours using the follwoing code but didn't work.

Book1 dataset is having a single record which is not taken into the final mereged file called "COMBINED_file" despite the fact its bank_number and account_number

are identically found in book2 talbe as well.

Could any help me?

Thanks

Mirisage

proc sort data=A.BOOK1 out=file_A;

by bank_number Account_number ;

run;

proc sort data=A.BOOK2 Out=file_B;

by bank_number account_number ;

run;

data COMBINED_file;

merge file_A (IN=a)

file_B (IN=b)

;

by bank_number account_number ;

if a and b;

run;

I am not sure if I understand what you are after. You code behaved the way it should. If you want to stack them, then use 'set' to replace 'merge', or if you don't want the variable from file_a being replace by file_b, then switch their order in the merge statement:

merge file_b(in=b) file_a(in=a);

or rename the variable names.

HTH,

Hi Haikuo,

Thanks.

Sorry for the confusion.

The final merged table that I want should look like below table. It should comprise all 5 records of Book2 data set and the single record of Book1 data set.

Please see the bottom-most row that I have bolded in below table. It is the single record that belongs to Book1 data set.

My merging code returns into the final merged table only the five records that belong to Book2 data set. And my code is not stacking the single record belongs to Book1 data set into the final merged table.
