Select with where condition comparing different domains

Question

SELECT *
           FROM table
           FOR ALL ENTRIES IN it_temp
           WHERE col1 =  it_temp-col_id.
col1 is of type char20
it_temp-col_id is of type char10.
"col1" and "it_temp-col_id" must have the same type and the same length.
do someone know a workaround?
thanks!!

types : begin of ity_temp_1,
               col_temp type table-col1, " this is type 20.
            endof ity_temp_1.
data: lt_temp_1 type standard table of ity_temp_1,
         ls_temp_1 type ity_temp_1.
loop at it_temp into is_temp.
    clear ls_temp_1.
    ls_temp_1-col_temp =    is_temp-col1. " passing col1(type 10 to col_temp of type 20.)
    append ls_temp_1 into lt_temp_1.
    clear : is_temp.
endloop.
"now lt_temp_1 holds matching domain.
SELECT *
FROM table
FOR ALL ENTRIES IN lt_temp_1 " comparing with passed values with same domain
WHERE col1 = lt_temp_1-col_temp.
