Home -> Community -> Mailing Lists -> Oracle-L -> RE: NEED YOUR OPINION
LYNDA,
If you look at my table staructure service_code in varchar2(30)and the data
in this column can be a number or a number start with a charachter(A-Z)like
A1200,B6500,Z9098 etc,in first subquery I want to select all those
service_code wich start with (0-9) then in WHERE Clause I use TO_NUMBER
becaz I know in subqury It returns all the numeric values:
E.G
select count(*)
> from (select MSC_SERVICE_CODE,MSC_MTF_SERVICE_ID
> from MTF_SERVICE_CODE_MSC
> where
> substr(MSC_SERVICE_CODE, 1, 1) in
> ('9','8','7','6','5','4','3','2','1','0')) a ----->>> reurn all service
code start with 0-9
> where
> to_number(a.MSC_SERVICE_CODE) between 7 and 30
--->> Here a.MSC_SERVICE_CODE convert it to TO_NUMBER .
Thanks allot

I believe that in your request you have a problem of conversion of a
varchar2 in number.
