The default format of the access database is:
1. The version before 2007 is .mdb .
2, 2007 and later versions are .accdb.
Access has a report creation function that can handle any data source it can access. Access provides functional parameterized queries. These queries and Access tables can be accessed by other programs such as VB6 and .NET through DAO or ADO. In Access, VBA can access parameterized stored procedures through ADO. Unlike general CS relational database management, Access does not perform database triggering, stored procedures or interactive login operations.
Access 2010 includes table-level triggers and stored procedures embedded in the ACE data engine. In Access 2010, tables, queries, charts, reports and macros can be developed separately in web-based applications. Access 2010 integration with Microsoft SharePoint 2010 has also been greatly improved.
Extended information:
In Access Basic, if you know the entry point (the name of the function in the dynamic link library), you can call the dynamic link library external function. However, the limitation of using this method is that you can only declare the external function once.
If you install the same Windows API that your module calls, you won't get an unknown error: trying to install a module with the same function definition. The module you are trying to install either contains the same function name or procedure name in an existing module.
To make your name unique, use the FIND command in the EDIT menu to find duplicate process names and delete these processes. You can also declare all your procedures called from a dynamic link library with initial values and underscore precedence.
