Merge table by Column Join?

Hi here is my problem-

I have two query output tables (sample data below):

 

kgiboin_0-1642426034900.png

 

I want to add columns to table 1 with the contract information from table 2, but only where the suppliers match, I.E SUP2 in Table 1 might not be equal to SUP2 in Table 2, or even be in that dataset for that matter.

 

Alternatively, If I can recreate Table 2 with only the suppliers that exist in Table 1 I can just load that new table next to Table 1. That also works.

 

I think I might be able to figure it out if I was to transpose the tables and do a join based on supplier names, but is there a better way to do that? not even sure thats doable yet.

Any Ideas?

Hi @kgiboin ,

 

1) Select the [Part Number] column in your first table (t1), then go to Transfom tab > Unpivot Columns (dropdown) > Unpivot Other Columns.

2) Do the same on your second table (t2).

2.5) At this point, you can edit the generated code (or just add a rename step) to rename your columns to something more useable than 'Attribute' and 'Value'. I will assume 'Attribute' has been changed to 'Supplier'.

3) Select the t1 query, then go to Home tab > Merge Queries.

4) In the merge dialog, multi-select (Ctrl+click) [Part Number], then [Supplier], in that order on t1 (top preview box).

5) Do the same (on the same columns, in the same order) for t2 (bottom preview box).

6) Hit ok and expand your resulting merged column.

 

This will firstly allow you to do a merge on two table dimensions at the same time and, secondly, will have structured your data in the most efficient format for reporting.
