How will get subquery return multiple values and passing to the main query

Question

Hi all ;
here i given one sql query
1)select decode(a.FLG,'Y','yes','N','no','null')||'] '||a.p_type||' : '|| initcap(replace(substr(b.mgr,0,instr(b.mgr,'@')-1),'.',' '))||' - '||
b.name||' ('|| substr(a.name,0,instr(a.name,'-')-1)||')'
from table1 a
join table3 c on c.emptype = a.emptype
left outer join table2 b on a.name = b.name
where a.mgrid = 100;
if i run this above query returning multiple values depend on sa.mgr values.
like output coming like this
[yes]:2000-anbarasan
[yes]:2700-anb
[yes]:2000-rasan
[yes]:2807-anbarasan
[yes]:2700-anbanu
[yes]:2000-null
2) this sub query i am passing with main query
select sa.mgrid,sa.sal,(select decode(a.FLG,'Y','yes','N','no','null')||'] '||a.p_type||' : '||
initcap(replace(substr(b.mgr,0,instr(b.mgr,'@')-1),'.',' '))||' - '||
b .name||' ('|| substr(a.name,0,instr(a.name,'-')-1)||')'
from table1 a
join table3 c on c.emptype = a.emptype
left outer join table2 b on a.name = b.name
where a.mgrid = 100)" test " from table4 sa,table5 te ,table6 ft where sa.id(+)=te.id and sa.mgr=ft.mgr;
my final out put required like this:
mgrid sal test
100 20000 [yes]:2000-anbarasan
[yes]:2700-anb
[yes]:2000-rasan
[yes]:2807-anbarasan
[yes]:2700-anbanu

Answer 1

Hi,
It doesn't look like you posted either the complete query or the complete error message (including line number). Try again.
"single row subquery return more then one row" usually means you are using a sub-query in a place where a single expression is expected, for example the column called avg_sal in this query:
SELECT  ename
,       sal
,       (SELECT  AVG (sal) FROM scott.dept WHERE deptno = e.deptno) AS avg_sal  -- Scalar-sub-query
FROM    scott.emp  e; The error occurs when the sub-query returns more than one row
If the sub-querry really is supoosed to be returning only one row, the solution is to fix the sub-query, usually be adding something to the WHERE clause.
If the sub-query is supposed to return more than one row, then the main query has to be re-written, perhaps as a join.
Post a little sample data and the results you want from that data if you need help.
