Access Continuous Form with Linked Table - How to Avoid Hitting Database Server for Every Row in Form?

阅读更多关于 Access Continuous Form with Linked Table - How to Avoid Hitting Database Server for Every Row in Form?

I'm migrating the data from an Access database to SQL Server via the SQL Server Migration Assistant (SSMA). The Access application will continue to be used with the local tables converted to linked tables. One continuous form hangs for 15 - 30 seconds when it's loading. It displays approximately 2000 records. When I looked in SQL Server Profiler to see what it was doing, it was making a separate call to the backend database for each record in the form. So the delay when the form opens is caused by the 2000-odd separate calls to the database. This is amazingly inefficient. Is there any way to

Access continuous form: Add a control without modifying the underlying table?

阅读更多关于 Access continuous form: Add a control without modifying the underlying table?

I'm making a simple Access form (continuous view). This has a checkbox in the Details section and a Command button in the footer. This way, the user can use the checkbox to "select" multiple records then click the command button at the button to run a script which updates the selected records. There's no need to permanently store these check values. Normally, I'd add a boolean field to the underlying table and associate the checkbox to that field. But is there a way to do this without modifying the table? i.e. store the checkbox values in memory? You could include record selection check boxes

问题 I'm using access 2007 and this behaviour can be replicated as follows. 1) Create new access database accdb file. 2) Open database and create new vba module. 3) Create 1st subroutine sub1: Sub sub1() Msgbox Err.Description End Sub 4) Create 2nd subroutine sub2: Sub sub2(Description as String) Msgbox Description End Sub At this point everything is normal. 5) But if I go and change sub2 so that 'Description' reads 'description', i.e. change 'D' to 'd' like so: Sub sub2(description as String)
