Use PLSQL to reverse the integer

Use PLSQL to reverse the integer. For example, if 123 is converted to 321, * Formattedon201571514: 56: 34 (QP5v5.163.1008.3004) * Average (idINNUMBER) limit (10); ls_last_itemVARCHAR2 (10 );

Use PLSQL to implement reverse order of integers. For example, 123 is converted to 321 without/* Formatted on 14:56:34 (QP5 v5.163.1008.3004) */create or replace function get_reverse_value (id in number) RETURN VARCHAR2IS ls_id VARCHAR2 (10); ls_last_item VARCHAR2 (10); ls_curr_it
