Ganesh,
Thanks a lot, when I am trying to test this I can see the following
behavior:
SQL> select decode(id_acc,123,(select count(*) from tab1),124,(select
count
(*) from tab1_mapper)) from tab1 where id_acc=123;
DECODE(ID_ACC,123,(SELECTCOUNT
------------------------------
64
SQL> select decode(id_acc,123,(select * from tab1),124,(select count(*)
fro
m tab1_mapper)) from tab1 where id_acc=123;
select decode(id_acc,123,(select * from tab1),124,(select * from
tab1_mapper)) from tab1 where id_acc=123
*
ERROR at line 1:
ORA-00913: too many values
SQL> select decode(id_acc,123,(select id_acc from tab1),124,(select
count(*
) from tab1_mapper)) from tab1 where id_acc=123;
select decode(id_acc,123,(select id_acc from tab1),124,(select id_acc from
tab1_mapper)) from tab1 where id_acc=123
*
ERROR at line 1:
ORA-01427: single-row subquery returns more than one row
It looks like it allows count(*) type of return from select but out actual
code is returing rows of data and oracle is throwing : too many values.
Let me know if there is workaround.
Thanks

Hi,
We are porting the application from SQL Server to Oracle, we have lot of
queries in the xml file and the application read the queries from the file.
In some scenarios we have following construct in sql server where we are
checking the value and depending upon it running one of the 2 sql's:
If (values = 'xyz')
Begin
Select….
End
Else
begin
Select…..
End
Oracle somehow don't like this construct and giving error : ORA-00900:
invalid SQL statement
What is the way to port this to oracle?
Thanks
