Question details
The user needs to resolve table structure and query errors that occurred after running the Analyze Table wizard in Access 2013.
- Product
- Microsoft Access 2013
- Device & OS
- not provided
- Scenario
- Fixing database functionality after the Analyze Table wizard inadvertently breaks table structures or queries by modifying lookup fields and splitting related tables.
- Observed behavior
- Table structures change, Combo Box lookup fields lose their properties, and existing queries return errors due to modified or missing related fields.
Before making structural changes to your tables or queries, verify which specific queries are failing and take note of the fields that the Analyze Table wizard recently modified.
Fix the List Rows Property in Lookup Fields
Restore missing or invalid List Rows properties for Combo Box lookup fields to ensure dropdown menus function correctly.
Running the Analyze Table wizard can sometimes reset or corrupt the properties of lookup fields. Specifically, the List Rows property for Combo Boxes may become blank or invalid, causing errors when trying to input data.
Right-click the affected table in the Navigation Pane and select 'Design View'.
Click on the specific field that is experiencing the lookup error. In the lower pane, click the 'Lookup' tab.
Ensure the 'Display Control' property is set to 'Combo Box'.
Locate the 'List Rows' property. If it is missing or invalid, enter a valid numeric value, such as 16, and save the table.
Update Queries for Decomposed Tables
Adjust existing queries to account for new table relationships created when the wizard splits a single table into multiple tables.

Frequently Asked Questions
What does the Analyze Table wizard do in Access?
The Analyze Table wizard evaluates your database design and recommends structural changes, such as splitting a large, redundant table into smaller, related tables to normalize data and improve database efficiency.
Why did my queries break after using Analyze Table?
When the wizard splits tables, it often replaces original text fields with numeric foreign keys. Existing queries that search for or output the original text fields will fail until they are manually updated to join the new tables.
How do I undo changes made by the Analyze Table wizard?
The Analyze Table wizard does not have a built-in undo button. If you did not choose to let the wizard create a backup query simulating your old table, you must manually reverse the structural changes or restore your database from a previous backup file.
