True. Another attempt: select * from MyTable where 2*length(MyField) != length(hex(MyField)); This relies on the fact that built-in function length() seems to stop (erroneously, in my opinion) on the first embedded NUL, while hex() doesn't seem to mind them. At least that's what happens with my copy of SQLite 3.7.2. Beyond this nasty hack, I can't think of anything short of writing a custom function. I tried LIKE and replace() - they don't work with embedded NULs either. -- Igor Tandetnik _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
