Answer 1

“why it is so..can u explain”I take it that you are unaware of what chr(10) does which you are using in your SQL statement.
Any clue what “\n” in ‘c’ programming does. When you try using it in printf statements or echo statements in UNIX shell - something similar.
It’s like a “line feed”. Breaks the string at that point and prints the remaining in the subsequent lines.
Visually, you will see the result appearing in separate lines (i.e 3 in your example) – It’s actually not 3 rows which is displayed but actually only 1 row.
In your example,
All commas ‘,’ in the string is replaced with chr(10) “line feed” (control character) thus making each name to appear in separate lines.
1 select rownum, 'AB', 'A' || chr(10) || 'B'
2* from dual
SQL> /
ROWNUM 'A 'A'
1 AB A
B
