Please help with this problem. I want to convert a number say 5000 of data type varchar2 to the same number of data type number but if i use say " select to_number(5000) from dual" the figure 5000 is left padded with space ie. ----5000 where - represents space.
How then do i remove such leading spaces so i can store the formatted number in a table.

Once you use the to_number function, the result is a number datatype. For display purposes, it may be right-aligned, but it is still a number.
In any case, you actually don't even need to explicitly convert the datatype (unless you want to), because Oracle will convert it implicitly.
sql>create table t (varchar2_column varchar2(10), number_column number);
Table created.
sql>insert into t values ('4000', null);
1 row created.
sql>update t set number_column = varchar2_column;
1 row updated.
sql>select * from t;
VARCHAR2_C NUMBER_COLUMN
---------- -------------
4000 4000 |
