Insert rows

SannaSanna — Tue, 17 Nov 2020 16:27:11 GMT

Hi. I have a table with categories that I need to merge into another table table. Unfortunately for me, there are no common columns to merge by. Can this be done? I need each row (from table1) to merge with every row in my second table. Does anyone have suggestions on how I may do this? I have over 10,000 rows from my first table that I must add from table 2. Here are a few records and an example of my expected output: Thank you for any help!

Table 1
ID	GEO
22454	C56
845880	C37
842387	C19

Table 2

PID_Item

LEF

FEH

PHE

MOH

Output:
ID	GEO	PID_Item
22454	C56	LEF
22454	C56	FEH
22454	C56	PHE
22454	C56	MOH
845880	C37	LEF
845880	C37	FEH
845880	C37	PHE
845880	C37	MOH
842387	C19	LEF
842387	C19	FEH
842387	C19	PHE
842387	C19	MOH

I need each row (from table1) to merge with every row in my second table.

This is called a Cartesian Join, and can be done in PROC SQL as follows:

proc sql;
    create table want as select * from table1,table2;
quit;

I concur with @PaigeMiller

You just need an extra ORDER BY for the grouped results-

proc sql;
 create table want as
 select a.*, pid_item
 from one a, two
 order by id;
quit;
