Form Query Process Flow(F11 -> Ctrl+F11)

F11查询过程:
1)WHEN-CLEAR-BLOCK

2)WHEN-NEW-RECORD-INSTANCE

3)WHEN-NEW-ITEM-INSTANCE


在输入查询条件后点CTRL+F11:
4)PRE-QUERY
Provide additional query criteria programmatically, just before sending the SELECT statement to the database.
Sample Code:
If :parameter.G_query_find = 'TRUE' then
  :trans_reasons.reason_id := :parameter.trans_reasons_qf;
  :parameter.G_query_find := 'FALSE';
end if;

5)WHEN-CLEAR-BLOCK

6)POST-QUERY
Perform an action after fetching a record, such as looking up values in other tables based on a value in the current record.  Fires once for each record fetched into the block.
在返回查询结果之后的做的动作,例如根据现在的查询结果去其他关联表中再查,再每个record塞进block的时候触发。每查一条记录,触发一次。

7)WHEN-NEW-RECORD-INSTANCE

8)WHEN-NEW-ITEM-INSTANCE
