I have a table named **Data** as below

```
g_name    g_id      v_data    
-----     ----      ------
Test      123        ABC
Test      123        DEG
Test      123        None
Test      123        
Test      123        HIJ

```

I want one select query which returns me values like below(in Oracle Database):

```
Value
------------
Test,123,ABC
Test,123,DEG
...
...
...

```

* `LISTAGG()` function is not working in `Oracle Forms Builder 12c`.
* There may be more than 3 columns. Thus, I need a dynamic way in order
to combine all columns together.

Can someone help me out here?
