Sure, you can, but it would require you to stop misusing dynamic sql, and *Learn* Pl/sql, instead of just hacking away. Actually you don't need it all for this statement, and an ordinary select into will just do fine. In that case you can refer directly to DayTimeValue.
Note: EXECUTE IMMEDIATE statements are always parsed. Using dynamic sql everywhere is the safest method to get awful performance. Seems you, without extensive reading and understanding the PL/SQL documentation, you are heading directly into a disaster.
