1. Microsoft Office 2003: Advanced 1 ADVANCED MICROSOFT ACCESS Lesson 10 – Analyzing Data

2. 2 Objectives Create basic queries. Build summary queries. Modify query design. Concatenate field values using a query. Create AND and OR queries.

3. 3 Terms Used in This Lesson AND query: Lets you find records in a query that meet more than one criterion. Concatenation: To combine text from two or more database table fields into one field. Criteria: In Access, information for which you are searching in a table or query. OR query: Lets you find records in a query that meet one criteria or another. Query: A search method that allows complex searches of a database.

4. 4 Query Design View Query grid

5. 5 Queries Fields that will display in query results

6. 6 Queries (cont.) Query results

7. 7 Saved Query After a query is saved and closed, if new records are entered into a table that match the query results, these records will display with the results the next time the query is run.

8. 8 Queries (cont.) Criteria row: By placing “north” in the Criteria row, only employees in the North region will display in the query results.

9. 9 Summary Queries You may select from a variety of summary calculations in the Total row.

10. 10 Summary Calculation Enter summary calculations in the Total row of the query grid. You must click the Total button first.

11. 11 Troubleshooting Tip If you go into the Expression Builder to create a calculation, when you close out of the Expression Builder, the expression will display in the query grid. However, you will need to change the name of the expression (which appears before the colon in the expression) by clicking in this grid cell, deleting the default Expr# text, and typing in a label for the expression.

12. 12 AND Query To create an AND query, place the criteria on the same criteria row. An AND query finds records that meet more than one criteria.

13. 13 OR Query OR queries require the criteria to be on separate Criteria rows to let Access know that you are not using an AND query.

14. 14 Copy a Query Queries can be changed before or after they have been saved. You can make a copy of a query and make changes to the copy’s query if you are not certain how their criteria changes will affect the query results.

15. 15 Summary You can summarize field values by creating a summary query. To concatenate text values in two or more fields, enter the concatenation expression in the query Design view.

16. 16 Summary (cont.) An AND query lets you search for records that meet more than one criteria. An OR query lets you search for records that meet one criteria or another. You can modify the design of a query by adding, inserting, changing, or deleting fields.
