A SELECT...INTO statement does implicit type conversion; this works
fine:

SELECT CHARS_A, CHARS_B FROM T INTO :NUMERIC_A, :NUMERIC_B;

If I execute it this way, I get a runtime error:

EXECUTE STATEMENT 'SELECT CHARS_A, CHARS_B FROM T' INTO :NUMERIC_A,
:NUMERIC_B;

CHARS_A, CHARS_B' INTO does not match returned column type

What is the expected behavior, and what can I do to have it cast
implicitly?
