MS Access: Creating Advanced Queries Instructor: Vicki Weidler Assistant: Joaquin Obieta
Overview • Use a select query to summarize and group data from different tables • Write a concatenation statement to combine values from different fields • Use the Find Unmatched Query Wizard to locate records that do not match between tables • Design a crosstab query to summarze grouped data • Create single- and multiple-criteria parameter queries • Learn how to use a wildcard in a parameter query • Create single- and multiple-field indexes to quickly sort and filter data in a table
Concatenation Concatenation is the process of combining values from different fields into one field
Find Unmatched Queries Use a Find Unmatched Query to view records that don’t have a matching record in another table Example: Locate customers who don’t have matching entries in the Orders table.
Crosstab Queries Display a summary of values based on two different types of information. Generally used to display large amounts of data in a compact format for easy review. Used to calculate averages, sums, or other totals on records, then group the results into two types of data. One group runs down the left side of the datasheet while the other runs across the top.
Parameter Queries A parameter query displays results based on criteria you specify each time you run the query. One or multiple parameters can be used.
Indexes Indexes are used to quickly sort and find data in tables. An index performs a search based on key values. Primary keys are automatically indexed.
