c. Find Duplicates Query Wizard: the query purposed to find duplicates records
d. Find Unmatched Query Wizard: to compare two tables and find records that the value is not matched.
3. Depends on the selected Wizard, the next dialog box will be varied.
In simple query wizard, select the table or query to taken from. Then, choose the fields to be taken and displayed.
4. Next, review the Query name. Then, you’re finished.
Create Query with Query Design
Creating query using query design is more recommended, because it has more options to show more than one table/queries along with the criteria.
1. After you selecting the Query Design, a query design window will appear, along with the Show Tables dialog box. Choose the tables/queries to be created.
2. In the table, double click the field to show it into the field grid.
Field: show the field name
Table: show the field’s table source.

Writing SQL in Query
With Query Wizards, you can create the query, but you cannot create the condition or criteria for query. To do that, follow these steps:
1. Open the previously created query. In Home tab, switch the view to SQL view.
2. Now, write the SQL code for query. The code is using SQL language so you must at least learn to code in SQL. The most basic syntax’s in SQL are:
SELECT [field1], [fieldn]
FROM [table1]
WHERE [criteria];
3. In the design tab, click Run to apply the changes.
