Methods
Methods:
Simple Query Wizard
Query Design View
Creating Multiple Table Queries

5. Query Design View Query grid Field identifies fields Lists in query
Criteria to limit records
Creating Multiple Table Queries

6. Sorting a Query on Multiple Fields
Sort orders are evaluated in a left-to-right order
Use the Show check box to sort on a field but not show it in the query datasheet
Creating Multiple Table Queries

7. Specifying Sort Orders
Primary
sort field
Secondary sort field
Creating Multiple Table Queries

8. Developing AND Criteria
AND criteria are entered on the same row of the query grid
AND criteria must both be true for the record to display in the datasheet
AND criteria further limit the number of records in the datasheet
Comparison operators or wildcard characters may be used in criteria
Creating Multiple Table Queries

9. Developing AND Criteria
AND criteria are entered on the same row
Creating Multiple Table Queries

10. Common Comparison Operators
Creating Multiple Table Queries

11. Developing OR Criteria
OR criteria are entered on different rows of the query grid
OR criteria may either be true for the record to display in the datasheet
OR criteria further expand the number of records in the datasheet
Comparison operators or wildcard characters may be used in criteria
Creating Multiple Table Queries

12. Developing OR Criteria
OR criteria are entered on different rows
Creating Multiple Table Queries

13. Criteria Wildcards
An asterisk (*) searches for any number of characters
A question mark (?) searches for any single character
A pound sign (#) searches for any single number
Creating Multiple Table Queries

14. Creating Calculated Fields
Create a calculated field in the field cell of the query grid
Calculated fields follow this pattern
NewFieldName:expression
Expressions may include field names, operators, and functions such as Sum
Surround field names in [square brackets]
Example: HourlyRate:[Cost]/[Hours]
Creating Multiple Table Queries

15. Creating Calculated Fields
[Cost]/[Hours] is the expression
HourlyRate is the new calculated field name

18. Building Summary Queries
A summary query calculates statistics about a group of records
Use the Total row in the query grid to specify how records are grouped and summarized
The datasheet of summary queries cannot be updated because each row represents several records

21. Building Crosstab Queries
Crosstab queries calculates statistics about a group of records using both a row and column heading
Use the Crosstab Query Wizard to create a crosstab query
Use the Total and Crosstab rows in the query grid to specify the crosstab settings
Creating Multiple Table Queries

22. Building Crosstab Queries
The Description field is the row heading field
The Location field is the column heading field
The Cost field is being summarized
Creating Multiple Table Queries

23. Building Crosstab Queries
The Location field is the column heading field
The Description field is the row heading field
The Cost field is being summarized
Creating Multiple Table Queries

24. Other Query Wizards
Find Duplicates Query Wizard finds whether a table contains duplicate values in one or more fields
Find Unmatched Query Wizard finds records in one table that do not have related records in another table
Creating Multiple Table Queries

25. Building PivotTables and PivotCharts
Use the PivotTable or PivotChart View of any existing table, query, or form
Changes made to either the PivotTable or PivotChart view are automatically applied to the other
Creating Multiple Table Queries

26. Building PivotCharts
Drag fields from the field list to the field locations on the PivotChart
Creating Multiple Table Queries

27. Building PivotTables Last is in the filter area
CourseID is in the column heading area
Cost is summed for each CourseID and Location
Location is in the row heading area
Creating Multiple Table Queries

28. Comparing PivotTables, PivotCharts, and Crosstab Queries
Creating Multiple Table Queries

29. Summary Select queries are the most common type of query
Use select queries to:
Select a subset of fields and records
Sort data
Create calculated fields
Use summary, crosstab, PivotTable, and PivotCharts to show summarized information
