Microsoft Access Query Wizard

Creating Microsoft Access Queries using the Query Wizards:

We can use the Microsoft Access Query Wizard to help create Crosstab Queries, as shown in a previous tutorial on Creating Crosstab Queries in Microsoft Access. In Access there are two other query wizards that are available to maintain the database, and these are:

  • Find Duplicate Query Wizard. This wizard will show duplicate records in a single Microsoft Access table, based upon the values of a field in the table.
  • Find Unmatched Query Wizard. Using this query we can show all records that do not have a corresponding record in another database table (for example, a Product with no associated Supplier, or an Employee with no associated Department)

The Find Duplicates Query Wizard works on a single table, whereas the Find Unmatched Query Wizard compares records in one table with records in another.

These query wizards, along with the Crosstab wizard as listed when you choose New Query in when viewing the Query Objects in the database window:

Find Duplicate Query Wizard

By using this query wizard, you can create a query that will allow you to search for records in a single table that are duplicated, based upon a field or fields. You specify in the wizard which fields that you want to use for checking duplication and you can also display further fields in your query results.

This wizard can help locate duplicate key violations - a good trick to use when you want to take an existing database table and make a unique (primary) key field with the existing data. If you try to create a unique key field and Access reports an error, you know that you have either duplicate records in the table or you have Null values in the field.

If using the Microsoft Access Find Duplicates Query Wizard still doesn't help you find what you need, you may want to check out the following product, which overcomes some of the shortfalls in the wizard:

Duplicates Finder automatically adds an AutoNumber field to your table if one is missing, enabling you to easily identify particular instances of duplicates.
  3. Duplicates Finder provides 12 different ways to query your table, facilitating your task of identifying, editing, and removing all duplicate records from your table quickly and efficiently.

Duplicates Finder overcomes a Find Duplicates Query Wizard’s shortcoming: With Find Duplicates Query Wizard, if you do not select additional fields to display on top of your duplicate fields, you end up getting a list of first instances of duplicates as opposed to all instances of duplicates! With Duplicates Finder you do not have to select additional fields.

Find Unmatched Query Wizard

This query wizard will allow you to create a query that reports any orphan or widowed records between two Microsoft Access tables.

An orphaned record is when a record in the many-side (child or related) table relationship has no corresponding record in the one-side (parent or primary) table. An example of this may be a Product in the Products table that does not have a Supplier in the Suppliers table, therefore the Product is an orphan record.

A widowed record is when the record in the one side of a one-to-many or one-to-one table does not have a corresponding record in the other table. You may have a Supplier who has no Products in the Products table.

You create the query, naming the two tables that you want to compare. You will need to specify the linking field between the two tables.

Using this query can assist in finding records that have no corresponding values in other tables. If, when you create a relationship between two Microsoft Access tables and try to Enforce Referential Integrity, Access reports that you cannot, it may be due to violating integrity. This query will help resolve this matter by locating the violating records.
