Home -> Community -> Mailing Lists -> Oracle-L -> RE: Convert LONG to VARCHAR2
Rick,
One way of doing this is:
Add a new column to the table with a type of Varchar2. Write a PL/SQL routine to convert the long to a varchar2. You can do this simply by assigning the long data type to a varchar2 variable:
create table tomtest(col1 long, col2 varchar2(100));
1 declare
2 cursor c1 is select col1,col2 from tomtest;
3 l_vc varchar2(100);
4 begin
5 for c1_rec in c1 loop
6 l_vc := c1_rec.col1; 7 update tomtest 8 set col2 = l_vc;
Obviously, you need a better 'where clause' in your PL/SQL. :)
Another way is to create a new table, and migrate the data using PL/SQL like above.
Hope this helps.
