hi,

Table Name Chk_cal

id number primary key
col_a varchar2(10)
col_b varchar2(10)

The following values are stored
Col_a Col_b
raju 12,765.12
kumar 34,567.12

I just want sum col_b and store it in memory variable

I tried

select sum(to_number(col_b)) into mem_vari from chk_cal;

Error has come as wrong numeric identifier

Any one can help me without disturbing the formated number

yours
dr.s.raghunathan

No
This is the price you pay for storing a "number" in a varchar2 field.
What is in col_b is NOT a number but a string.
It is not valid to "sum" decimal point characters and/or comma characters.

TO_NUMBER can take a format.
Why are you storing numbers in varchar2 columns? This is really stupid.
