LAST_QUERY in Form and OAF Page

1.Form里查看Last_Query

SYSTEM.LAST_QUERY

Represents the query SELECT statement that Oracle Forms most recently used to populate a block during the current Run form session. The value is always a character string.

从上面的Last_Query定义的解读：
1.SYSTEM.LAST_QUERY返回的只能是查询(Select)的SQL语句，不会有Update,Insert,Delete SQL语句;
2."The current Run form session"说明不同的Form，SYSTEM.LAST_QUERY可以有不同的值的，不会混淆;
3."Used to populate a block"说明只有查询类的Block，才能查出值来。所以不要指望，执行一个LOV后，SYSTEM.LAST_QUERY返回一个查询语句

System.Last_Query的业务处理的逻辑代码写在框架APPCORE.pld

2.OAF页面如何查看Last_Query
