Question

I am using IBM BPM V8.5.7. I want to use a single select to select an item which are retrieved via a service. The problem is that the service returns 10k+ items and I currently use a search function. What I want to achieve basically is to search in the single select dropdown and whilst doing that it must fire the service and return the search results.

I have managed to get the search function working properly but searching through so many items slows down BPM. I've tried using a piece of code but that just cleared the items once the service was called

您的DB-Select可能看起来像这样：

SELECT name, value FROM YOURTABLE

这会给您的ibm控件带来压力（您使用的是经典控件还是其他类似顶点的控件）？尝试从您的SQL查询中限制结果集。一个例子可能是：

SELECT name, value FROM YOURTABLE  FETCH FIRST 100 ROWS ONLY

（请注意，这是DB2样式）-在MS SQL中如下所示：

SELECT TOP(100) name, value FROM YOURTABLE

Loading items from service into a single select
