Tutorial 3: Maintaining and Querying a Database

New Perspectives Access 2010 Tutorial 3: Maintaining and Querying a Database Key Terms aggregate function A function that performs an arithmetic operation on selected records in a database. (AC 151)

And logical operator The logical operator you use in a query when you want a record selected only if two or more conditions are met. (AC 141)

AutoFilter An Access feature, available by clicking the arrow to the right of a field name in Datasheet view for a table or query, that enables you to quickly sort and display the field’s values in various ways. (AC 123) calculated field A field that you create with an expression that displays the results of the expression in a datasheet, form, or report, but does not exist as a field in the database. (AC 146) comparison operator In a query, an operator that asks Access to compare the value in a database field to the condition value and to select all the records for which the relationship is true. (AC 130) condition A criterion, or rule, that determines which records are selected in a query. (AC 130) design grid The portion of the Query window in Design view in which you specify the fields and record selection criteria for the query you are creating. (AC 110) editing mode The mode in which you can insert or delete characters in a field value based on the location of the insertion point. (AC 112) exact match A type of query in which the value in the specified field must match the condition exactly in order for the record to be included in the query results. (AC 131) expand indicator In a datasheet, the plus sign that lets you display the related records in the subdatasheet. (AC 116) expression A statement containing a combination of database fields, constants, and operators that you define in a query to perform a calculation. (AC 145)

Expression Builder An Access tool that makes it easy to create an expression by providing boxes for entering the expression, options for displaying and selecting common operators, and one or more lists of expression elements, such as table and field names. (AC 146)

F2 key The function key you press to switch between navigation mode and editing mode in a datasheet. (AC 112) filter A set of restrictions you place on the records in an open datasheet or form to temporarily isolate a subset of the records. (AC 127)

Filter By Form A filtering technique that changes a datasheet or form to display blank fields, allowing you to select a value from a list in any blank field to apply a filter that selects only those records containing that value. (AC 127)

Filter By Selection A filtering technique that lets you select all or part of a field value in a datasheet or form, and then display only those records that contain the selected value in the field. (AC 127)

Find command A command you use to search for data in a form or a table or query datasheet so that you can locate a specific field value or part of a field value. (AC 113)

Group By operator In a query, an operator that divides the selected records into groups based on the values in the specified field. (AC 154) logical operator In a query, an operator that allows you to combine two or more conditions. (AC 141) navigation mode The mode in which Access selects an entire field value, and your typed entry replaces the highlighted field value. (AC 112) nonunique (sort field) A sort field for which more than one record can have the same value. (AC 124)

Object Type The default category in the Navigation Pane; it arranges objects by type (tables, queries, forms, reports, and so on). (AC 155)

Or logical operator The logical operator you use in a query when you want a record selected if at least one of the specified conditions is met. (AC 141) plus sign (+) In a datasheet, a symbol indicating that records have related records in another table. (AC 115) primary sort field The first sort field specified that determines the order of records in an object. (AC 124) query by example (QBE) An example of the information you are requesting from Access in a query. (AC 111) recordset The set of records that results from running a query. (AC 117) run (a query) To answer a query and display the results. (AC 110) secondary sort field A second field that determines the order of records in an object that are already sorted by the primary sort field. (AC 124) select query A query in which you specify the fields and records you want Access to select, and the results are returned in the form of a datasheet. (AC 110) sort To rearrange records in a specified order or sequence. (AC 123) sort field The field used to determine the order of records in a datasheet. (AC 123) subdatasheet A datasheet that displays the records related to the current record. (AC 116) theme A predefined set of formats including colors, fonts, and other effects that enhance a database object’s appearance and usability. (AC 137) unique (sort field) A sort field whose value is different for each record. (AC 124) update (a database) To add, change, and delete records in database tables to keep them current and accurate. (AC 112)

Zoom box A dialog box you can use to enter text, expressions, or other values. (AC 146)
