Thread: new calculated column

Hi;

I've got a table with two fields and about 3000 rows, the second one is a
character field, what can have about twenty different values; of course these
values are repeated a lot of times in the table. I need to create a new
column of type integer, whose value depens on the character fields. The
values of the new column are not important, the important thing is who can I
create this column and assign a different integer to a different char value
in the other column.
Thanks

HI.


simple (tedious) solution would be do fire 20 sqls.


update tabel set f1=<some int 1> where f2='some varchar1';
update tabel set f1=<some int 2> where f2='some varchar2';
update tabel set f1=<some int 3> where f2='some varchar3';

incase there is some the integer is a function of varchar
u may translate to the corresponding SQL.
