I need to get a result table from an sql query.
Suppose i have 2 columns A,B. The column A contains multiple values which can be similar or distinct. Column B contains only 2 values 1 or 2. I tried the group by but i am getting all the results as different rows.
How can i expect a query which can return all the distinct values of A in a single row with one value of B.
Rough Data
| A | B | 
|---|---|
| ex1 | 1 | 
| ex2 | 1 | 
| ex3 | 2 | 
| ex4 | 2 | 
Expected Data
| A | B | 
|---|---|
| ex1,ex2 | 1 | 
| ex3,ex4 | 2 | 
select ....
group by a,b
