What can we use in Select Query instead of cursor - sql

Question

I do not want to use cursor in my select query directly but I could not find any alternative ways to use.
My first query is
select 'Joe' as Name,'Last' as LastName, cursor(select * from temp) as Details from dual;
Table Temp:
A
B
C
1
2
3
2
3
4
OUTPUT:
Name
LastName
Details
Joe
Last
{<A=1,B=2,C=3>,<A=2,B=3,C=4>,}
I do not want to use cursor in select query directly. Is there any different usage of "cursor(select * from temp) as details"?
If it is possible in Declare begin end statments, it will be okay too. I am getting error when I try below way.
DECLARE
cursor cur is (select * from temp);
x cur%rowtype
BEGIN
open cur;
loop
fetch cur into x;
end loop;
close cur;
SELECT NAME,LASTNAME,CUR FROM DUAL;
END;
Error:
Expression is of wrong type

Answer 1

Well, what do you want to get as a result?
This is what you have now:
SQL> select 'Joe','Last', cursor(select * from dept) as details from dual;
'JO 'LAS DETAILS
--- ---- --------------------
Joe Last CURSOR STATEMENT : 3
CURSOR STATEMENT : 3
DEPTNO DNAME LOC
---------- -------------- -------------
10 ACCOUNTING NEW YORK
20 RESEARCH DALLAS
30 SALES CHICAGO
40 OPERATIONS BOSTON
SQL>
Would this be OK for you?
SQL> select 'Joe', 'Last', d.deptno, d.dname, d.loc from dept d;
'JO 'LAS DEPTNO DNAME LOC
--- ---- ---------- -------------- -------------
Joe Last 10 ACCOUNTING NEW YORK
Joe Last 20 RESEARCH DALLAS
Joe Last 30 SALES CHICAGO
Joe Last 40 OPERATIONS BOSTON
SQL>
[EDIT]: a function that returns refcursor
SQL> create or replace function f_temp return sys_refcursor is
2 l_rc sys_refcursor;
3 begin
4 open l_rc for select * from temp;
5 return l_rc;
6 end;
7 /
Function created.
SQL> select 'Joe','Last', f_temp
2 from dual;
'JO 'LAS F_TEMP
--- ---- --------------------
Joe Last CURSOR STATEMENT : 3
CURSOR STATEMENT : 3
A B C
---------- ---------- ----------

Answer 2

You can wrap your cursor into xmltype() , for example:
select
'Joe'
,'Last'
,xmltype (cursor(select * from temp)) as details
from dual

Answer 3

You may create a function that returns desired string to you, and then invoke the function in your SELECT
select 'Joe' as Name,'Last' as LastName, funcDesiredString() as Details from dual;
The function's logic would be something like this -
desiredDetails := '{';
for rec in (Select A, B, C from Temp)
Loop
desiredDetails := desiredDetails || '<A=' || rec.A || ',B=' || rec.B || ',C=' || rec.C || '>,';
End Loop;
desiredDetails := TRIM(',' FROM desiredDetails);
desiredDetails := desiredDetails || '}';
