Access Problem running update queries on linked-in Excel Spreadsheets Jim S To my surprise and chagrin, newer versions of Access have disabled the functionality that lets users change the data in linked tables that point to a range in an Excel workbook.
When you split a database, you put the data tables in a database file on a network server in what is called a back-end database. You put the other database objects, such as queries, forms, and reports, in another database file that is called the front-end database. Users keep their own copy of the front-end database on their computers. Performance will improve because only the data is sent across the network. Access locks a certain amount of data while you edit records.
The amount of data that is locked depends on the locking setting that you choose. You can help improve performance by choosing page-level locking. However, page-level locking may decrease data availability, because more data is locked than with record-level locking. Page-level locking Access locks the page that contains the record the page is the area of memory where the record is located. Editing a record with page-level locking enabled might also cause other records stored nearby in memory to be locked.
However, performance is generally faster when you use page-level locking instead of record-level locking.
Record-level locking Access locks only the record that is being edited. Other records are not affected. In the right pane, in the Advanced section, select or clear the Open databases by using record-level locking check box. Access locks records while you edit them. The number of records that Access locks and the amount of time those records are locked depends on the record-locking setting that you choose.
No locks Access doesn't lock a record or page until a user saves changes to it, which results in data being more readily available.
However, data conflicts simultaneous changes being made to the same record can occur if you use this setting. When a data conflict occurs, the user must decide which version of the data to keep. This is generally the fastest option, but data conflicts may outweigh the performance gain.
Edited record Access locks a record as soon as a user begins to edit it. As a result, records are locked for longer periods of time, but data conflicts are less likely.
All records Access locks all the records in a table while any form or datasheet that uses that table is open. This can improve performance for the user who is editing data in the table, but it restricts other users' ability to edit data more than the other options do. In the right pane, in the Advanced section, under Default record locking , click the option that you want.
Try adjusting the Refresh interval sec , Update retry interval msec , Number of update retries , and ODBC refresh interval sec settings, as applicable. You use the Update retry interval and Number of update retries settings to specify how often and how many times Access tries to save a record when it is locked by another user. Refreshing only updates data that already exists in your datasheet or form. Refreshing does not reorder records, display new records, or remove deleted records and records from query results that no longer meet specified criteria.
To view such changes, you requery the underlying records for the datasheet or form. In the right pane, in the Advanced section, change the settings that you want. The following guidelines can help improve Access performance, regardless of whether the database with which you are working is stored on your computer or on a network.
