AB
ascending sorta sort order that sorts text values from a to z and number values from 1 to 10
calculated fielda field in an access query, form, or report in which the displayed values are the result of calculations performed on other fields
concatenationin access, joining to values to display them as a single value for example, if you concatenate a FisrtName field to a LastName field, as in [FirstName]&[LastName], the two names are displayed as a full name in a single field
criteriaa limiting condition, such as “Arizona” or “>100” used in access queries and filters to show a limited set of records
descending ordera sort order that sorts text values from z to a and number values from 10 to 1
expression- a formula that calculates, a value or defines criteria; in access, you can use an expression to calculate new values or to specify which records should be displayed
filterin access, one or more criterion that you can apply to a datasheet to display a subset of records. Those records that do not meet the criterion are “filtered out” and are not displayed in the subset of records
filter by fromin access, a filtering technique in which you can type the values for which you want to filter using a form that contains all the fields in the datasheet
filter by selectionin access, a filtering technique in which you select a value for which you want to filter using the filter by selection button
select querythe most common type of query in access, the select query retrieves specific data from one or more tables and displays the results in a datasheet; however, it does not alter the data in the table(s). you can sort and summarize the results of a select query, and you can perform calculations on the filed in a select theory
