Question

I’m having trouble figuring out how to correctly merge rows. Looking at the sample table below:

TYPE  | NAME   | COLOR | DESCRIPTION
=================================
Fruit | Apple  | Red   | -----    
Fruit | Apple  | ----- | sweet    
Fruit | Orange | ----- | ripe

What I want to do is merge the rows 1 and 2 so that rows with the same type and name will have a single row and its values be merged as one row.

Is there a way to do this?

Answer 1

It sounds like you just want

SELECT type, 
       name, 
       MAX(color) color, 
       MAX(description) description
  FROM table_name
 GROUP BY type, name;
