Return value based on another field using a muilti-value field

[pyroman26]

Here is my data in the table:

Index Field1 Field2
1 0 A,B,C
1 -5 D,E,F
1 -10 G,H,I

I have a complex query that returns a single row of data that includes index, field1 (as a multi-value field) and field2 (as a multi-value field) like:

1 0,-5,-10 A,B,C,D,E,F,G,H,I

I can get field 2 to return just one value by utilizing the min command that gives me the desired result. If I use the mvexpand field2 I limit the result to index =1, I get the below result:

1 -10, A,B,C

Looking at the data, I want the row for field2 to be the row that corresponds with the the value of the min statement. For a result of:

1, -10 G,H,I

Hope this makes sense. What I am really looking for is the query to return the value based on the value of another field knowing that I currently get have the result in a multi-value field.

Hi, It's strange when it comes from dummy data.
