Data types Access and SQL Server have similar data types, but be aware of the following potential issues. You can use this data type to efficiently calculate large numbers but it requires using the Access 16 For more information, see Using the Large Number data type and Choose between the bit or bit version of Office.
If the compatibility level of the database is SQL Server or higher, and a linked table contains one or more datetime or datetime2 columns, the table may return the message deleted in the results.
Use the datetime2 data type which has a larger date range than datetime. When querying for dates in SQL Server, take into account the time as well as the date. For example: In SQL Server, you have several options to consider. You can extract the files from the Access database and then consider storing links to the files in your SQL Server database.
By default, these columns will be converted to nvarchar max columns in SQL Server, but you can customize the mapping to choose a smaller data type. In your Access solution, you can still use the hyperlink behavior in forms and reports if you set the Hyperlink property for the control to true. Because SQL Server does not support a multivalued data type that models a many-to-many relationship, additional design and conversion work might be needed.
In most cases, these queries should be converted to pass-through queries. SQL Server cannot run these user defined functions. You may need to manually redesign these functions and convert them to stored procedures on SQL Server.
Optimize performance By far, the most important way to optimize performance with your new, back-end SQL Server is to decide when to use local or remote queries.
When you migrate your data to SQL Server, you are also moving from a file server to a client-server database model of computing. Follow these general guidelines: Run small, read-only queries on the client for quickest access. Minimize network traffic with filters and aggregation to transfer only the data you need. For more information, see Create a pass-through query. The following are additional, recommended guidelines. Stand-alone download managers also are available, including the Microsoft Download Manager.
You may not be able to download multiple files at the same time. In this case, you will have to download the files individually. You would have the opportunity to download individual files on the “Thank you for downloading” page after completing your download.

The Microsoft Download Manager solves these potential problems.
It gives you the ability to download multiple files at one time and download large files quickly and reliably. It also allows you to suspend active downloads and resume downloads that have failed. Microsoft Download Manager is free and available for download now.
