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.
