我想链接 LOV 和 Select 列表。 （甲骨文 APEX 21.1）

Question

I want to change the "Select List" List when the LOV (P2_LOV_ID) is changed.

I tried setting

• Actions - Settings - Set Type: SQL Statement

• SQL Statement:

   SELECT SHOP_NAME, GROUP_ID FROM T_ENTRY_SHOPS WHERE ID=:P2_LOV_ID;

With the same Action and SQL, the value displayed in the Text Field shows the expected SHOP_NAME . ( GROUP_ID column is not displayed. Maybe it's because that Text Field has not multi columns)

But "Select List" List does not change. Was it the wrong property on Action?

Answer 1

"LOV" stands for "List of values". It is used in a "Select list item". So far so good.

That SELECT statement's result depends on another item - P2_LOV_ID .

In that case, you'll have to modify Select item's properties:

• navigate to "Cascading list of values" property group
• set " Parent item(s) " to P2_LOV_ID

It means that - when you change P2_LOV_ID 's value, the next LoV will display different values (that depend on the parent item).
