问题 When creating a new database in Access 2007, should ADO (ActiveX Data Objects) or DAO (Data Access Objects) be used?

问题 Access 2007 databases querying linked oracle 10g tables are returning flawed result sets when using the WHERE clause to filter-out unwanted records. Oddly, some filtering is happening, but not reliably. I can reliably demonstrate/produce the problem like this: Create a *new* database with Access 2007. Create a second *new* database with Access 2007, and then "save-as" 2000. Create a third *new* database with an older version of Access. Run the following query in each database: SELECT STATUS,

问题 I have an append query that is trying to append some records to one of my tables.

问题 I have a front-end Access 2007 database connecting to MySql tables using MySQL ODBC connector. The problem is that a form linked to a table will not refresh its data if the data are changed by another user on the network or if the data was changed by a pop-up form.
