SQLite Select data from multiple rows returned as one row

Question

I would like to know whether it is possible to use a SELECT statement in SQLite to merge the data from two rows into one, similar to how is suggested in the SQL Server forum

Answer 1

Doug's solution didn't work for me. The code below, however, did work for me but it's very slow...

SELECT 
   a.ID, 
   a.Name AS Name1,
   (SELECT b.Name FROM Emp b 
             WHERE b.ID = a.ID
             AND b.Name != a.Name LIMIT 1) AS Name2
FROM emp a 
GROUP BY a.ID

Answer 2

SELECT 
   a.ID, 
   COALESCE(a.Name,'') as "Name-1", 
   COALESCE((SELECT b.Name FROM Emp b 
             WHERE b.ID = a.ID
             AND b.rowid != a.rowid LIMIT 1),'') as "Name-2"
FROM emp a 
GROUP BY a.ID

Answer 3

try this:::

select id, group_concat(name) from emp group by id;
