buffer overflow error is not due to cursor. Do you have any dbms_output.put_line statements in your program?.
run following stmt
set serveroutput on size 100000
alter table to drop column.
alter table tablename drop column colname;

hi suresh,
To increase the buffer size use
dbms_output.enable(1000000);
this statement is first statement in your code.
next question i am not clear that yr asking a column of object in 8i concepts or from ordinary table.
if this from ordinary table there is no specific syntax for to delete a column. But u can do another way.
create a table with required columns
drop old table
rename new table to old table
if it is related to 8i objects refer the syntax given on oracle 8i documentation

hai sanjib,
To drop a column , give the follwing command in sql prompt ,It will work only in oracle8i.
alter table
drop column <column_name>;
If you are having only one column it won't allow to drop.
If the column having any master detail realtionship it won't allow.
Cursors:
If you have been used the cursor in infinte loop,there may be chance for buffer overflow.
So pls check your program.
Regards,
Muruganantham.
