问题描述
我正在使用的功能正常。唯一的问题是响应时间有点长。任何人都可以帮忙这个
感谢您提供
我尝试过：
Below function i have which is working correctly. The only issue with is response time is a bit longer. Can anyone help with this
Thanks in adv

It too long code to execute for each request. Try to create simplified objects a
for each database query.Creating a datatable on the go retrieve DataTable from database as
an object and manipulate that DataTable as per requirement. After looking at your queries
it seems your database needs to be normalized to get better efficiency and quick response.
Please see the code part

this part shows database design needs more care. A single query can retrieve whole database
so why query in loop? A single hit at server takes some specific time. If a single query
is hitting 1000 times the response delay will increase exponentially.
So my suggestion is to re-design database and a single query should bring up a DataSet and
then play with dataset in memory. It needs more RAM but page can be loaded
within 5 seconds.
