Your simpler method doesn’t work,
it didn’t put all cases into consideration.

For example when str_num = ‘1+)2+(3+4′

SQL> select str_num,
2 case when length(replace(str_num,’)')) = length(replace(str_num,’('))
3 then ‘T’ else ‘F’ end bal
4 from ( select ‘1+)2+(3+4′ str_num from dual);

STR_NUM BAL
——— —–
1+)2+(3+4 T

The correct answer should be “F”.

ArrayDescriptor descp= ArrayDescriptor.createDescriptor(”schemaname.EMP_TYP_TABLE”,dconn).

oci:217300 object schemaname.EMP_TYP_TABLE is not found or is marked for delete.can u plz help me with this !

Your other alternatives are views and/or programmatic interfaces built out of PL/SQL.

Cheers, APC

1) Learn and understand every new SQL features/functions in the manual
2) Thinking outside of the box and attack the problem from different directions.
Don’t limit your mind set to the conventional approach.
3) Draw diagrams if needed.
4) Implement the solution in layers,
Write the inline view on top of each other as if you are implementing a function.

SQL> desc testit
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 OPERATOR_NAME                                      VARCHAR2(10)
 NUMBERS                                            VARCHAR2(50)
 LOC                                                VARCHAR2(10)

And, my input dataset looks like this:

SQL> select * from testit;

OPERATOR_N NUMBERS                                            LOC
---------- -------------------------------------------------- ----------
sony       9848930997-9848931000                              pune
o2         65432-65435                                        hyd
voda       369852-369855                                      mum
orange     9290988345-9290988345                              blore

One solution, though I’m not convinced it’s optimal, is this:

SQL> l
  1  with source_data as
  2  (select operator_name,
  3          substr(numbers,1,instr(numbers,'-')-1) start_num,
  4          substr(numbers,instr(numbers,'-')+1) end_num,
  5          loc
  6     from testit)
  7  select distinct operator_name,
  8                  start_num+level-1 numbers,
  9                  loc
 10    from dual,
 11         source_data
 12   connect by level <=end_num-start_num+1
 13* order by 1,2,3
SQL> /

OPERATOR_N    NUMBERS LOC
---------- ---------- ----------
o2              65432 hyd
