So I would in fact select all of the tables for one given database, check the prompt for new location , and then create a FILE dsn they are the default anyway.

Once you link, then do the same for all the other tables that point to the other database. Again re-link. The result will be a dsn-less connection, and thus your application will work on any workstation on the network, and do so without having to setup a dsn of any kind on each workstation.

Having said all of the above, it not clear if this issue is related to your errors, or instabilities in your application.

If so, you could standardize them and check what impact that change has on the other issues. I'm not sure. This database has had recurring "unrecognized format" errors over the past month or two The problem still occurs periodically. At this point, I'm looking for anything that inconsistent.

I have a few other databases with similar issues, though none with the persistency of this one. Add a comment. Sorted by: Reset to default. Highest score default Date modified newest first Date created oldest first. You can use the linked table manager to do this, but likely code is better. Albert D. Kallal Albert D. Kallal Albert - Thank you so much for your thorough answer!

In the navigation pane, right click a table linked to the desired data source, and select Linked Table Manager. In the Linked Table Manager dialog box, select the check box of the data source, and then select Edit. In the Edit Link dialog box, copy the text in the Connection string box.

Select Build. Follow the prompts to create a DSN file that contains the connection string information. This ensures the query has correct syntax. If the query returns records, set this property to Yes ; if the query doesn't return records, set this property to No. Note Pass-through queries can return multiple result sets, but in a datasheet, form, report, or recordset variable, only the first result set is used.

To retrieve multiple result sets, use a make table query as the following example shows:. Each result set is saved in a separate table and numbers are appended to the local table names accordingly. The table name has the format, username — nn, where username is the sign in name for the current user, and nn is a number starting at ODBC Timeout Specify the number of seconds to wait before a time-out error occurs when a query is run.

The default value is 60 seconds. There may be delays due to network traffic or heavy use of the database server. Max Records Specify the maximum number of records to return. You may have limited system resources or you want to test your results with just a small amount of data. Your query is sent to the database server for processing. Transact-SQL Reference. Querying with Transact-SQL. SQL Server migration. To obtain a connection string: In the navigation pane, right click a table linked to the desired data source, and select Linked Table Manager.

Recall the halcyon days of youth when alphabet soup was your fun meal. Keep these happy thoughts in the back of your mind as we take a few tastes of the database version of alphabet soup. The following sections spell out the basics of getting to a database with connection strings and using a database programming interface in your Access VBA code. Summary of ODBC driver versions. ODBC keyword summary. OLE DB keyword summary. Connection strings have been around a long time.

You can define a formatted connection string either in the Access user interface or in VBA code. A connection string whether ODBC or OLE DB passes information directly to the database, such as server location, database name, type of security, and other useful options.

For example:. Many legacy applications used SNAC and it is still supported for backward compatibility, but we don't recommend using it for new application development. You should use later individual, downloadable versions of the ODBC drivers.

These components still ship with Windows for backward compatibility. Although there is no way from Access to open the Data Link Properties dialog box, in Windows Explorer, you can create an empty.

After you create a connection string, change the file type back to. It was deprecated in How to optimize performance with an ODBC connection string. To optimize performance, minimize network traffic, and reduce multi-user access to the SQL Server database, use as few connection strings as possible by sharing connection strings over multiple record sets. If the retry is successful, you can continue working. To reconnect, close and re-open Access.

Avoid mixing connection string and database access technologies. The terms describe the same type of software component but are not interchangeable in connection string syntax. Use the correct value as documented. Top of Page. A data access object DAO provides an abstract interface to a database. Microsoft Data Access Objects DAO is the native programming object model that lets you get at the heart of Access and SQL Server to create, delete, modify, and list objects, tables, fields, indexes, relations, queries, properties, and external databases.

For more information, see Microsoft Data Access Objects reference. ADO is straightforward to learn and enables client applications to access and manipulate data from a variety of sources, including Access and SQL Server. Its primary benefits are ease of use, high speed, low memory overhead, and a small disk footprint. ADO also supports key features for building and Web-based applications. DAO continues to be the default in Access. For example, all forms and reports and Access queries use DAO.

The following table summarize important information about ODBC driver versions, download locations, and feature support. Make sure you use the correct bit version bit or bit of the driver based on Windows and not Office.

If you are running bit Access on bit Windows, install bit drivers, which includes the bit components needed for Access. Using XA Transactions. Data Classification. Always Encrypted. Azure Active Directory.
