Use something like is:
char buffer[1024];
//char_pointer_for_field1 AND char_pointer_for_field2 are char*
//type variables

buffer = sprintf("INSERT INTO TABLE(field1,field2) VALUES('%s','%s'),
char_pointer_for_field1, char_pointer_for_field2
);

NOTE: You may have to use a bigger buffer string. This depends on the
length of variables char_pointer_for_field1 and char_pointer_for_field2.
If for some reason the buffer space reserved is smaller, it means that the
previous sprinf instaruction will *corrupt* other SO memory...and you will
notice an error like: Segmentation fault.
