Merge two tables with different number of columns

Maria_Frankfurt — Mon, 16 Oct 2017 03:38:07 GMT

Hello,

I want to merge two tables with different number of lines in a horizontal layout. Table 1 has two rows, table 2 has six rows. The goal (table 3) is a table with five rows. The two rows are like a header, table 2 includes the data that belongs to those sentences.

I have tried different ways to merge the tables. I have either two many sentences, or some data is missing.

Please check the attachments, for the data. I think hat can explain better what I want.

I work in SAS Enterprise Guide with a sas programm on Version 9.2.

Thank you.

Ok...what are the rules here for creating Table 3?

Re: Merge two tables with different number of columns

Maria_Frankfurt — Mon, 16 Oct 2017 04:14:54 GMT

Hi Reeza,

Merge the tables with key1, it's unique.

Tab1_Field1, Tab1_Field2, Tab1_Field3 are header fields.

match Tab1_Field4 with Tab2_Field1 as a group 1 with Tab2_Field2 Tab2_Field3 Tab2_Field4 Tab2_Field5 Tab2_Field6 Tab2_Field7 Tab2_Field8
match Tab1_Field5 with Tab2_Field1 as a group 2 with Tab2_Field2 Tab2_Field3 Tab2_Field4 Tab2_Field5 Tab2_Field6 Tab2_Field7 Tab2_Field8
match Tab1_Field6 with Tab2_Field1 as a group 3 with Tab2_Field2 Tab2_Field3 Tab2_Field4 Tab2_Field5 Tab2_Field6 Tab2_Field7 Tab2_Field8

The goal is to match the three groups on Key1 and on the Tab1_Field4, Tab1_Field5, Tab1_Field6.

Result is in table 3.

I hope this helps to understand.

Unfortunately this is more than I have time for tonight, if someone else doesn't answer this I'll take another look tomorrow.

Re: Merge two tables with different number of columns

The easiest way I see is to transpose table_1 so that fields 4, 5 and 6 are stacked vertically, then do the merge, and then re-transpose to the wide format.

If the wide format is needed at all, as it's usually easier in SAS to stay in a long format.

Maria_Frankfurt — Mon, 16 Oct 2017 15:43:32 GMT

@Kurt_Bremser: Thank you for your advice. I tried transpose and I got a little further. But it is still not working how I want it.

First: I have to update my table3, my desired result.

My Goal looks like this:

Key1	Tab1_Field1	Tab1_Field2	Tab1_Field3	Tab1_Field4	Tab2_Field2	Tab2_Field3	Tab2_Field4	Tab2_Field5	Tab2_Field6	Tab2_Field7	Tab2_Field8	Tab1_Field5	Tab2_Field2	Tab2_Field3	Tab2_Field4	Tab2_Field5	Tab2_Field6	Tab2_Field7	Tab2_Field8	Tab1_Field6	Tab2_Field2	Tab2_Field3	Tab2_Field4	Tab2_Field5	Tab2_Field6	Tab2_Field7	Tab2_Field8

To make it easer to understand my problem, I created table01 and table02 in sas. I was able to transpose table01 and then merge table01 and table02.

But after that I am stuck, I don't know how to transpose my result back to horizontal layout to match my table3.

Here ist my code:

data table01;

format key1 $16. Tab1_Field1 $13. Tab1_Field2 $3. Tab1_Field3 $5. Tab1_Field4_1 $15. Tab1_Field4_2 $15. Tab1_Field4_3 $15. ;

I still question any reason for such an unwieldy and complicated dataset structure, that will only make working with the data harder and solves (IMHO) no purpose.
