Exercise 6-3 7 You can add fields to the design grid of a query by any of the three following ways: Double-click the field name in the Field List. Drag the field from the Field List to a Field row in the design grid. Click the Field row in the design grid and select a field name from the drop-down list.

11. a lesson approach © 2011 The McGraw-Hill Companies, Inc. All rights reserved. Exercise 6-5 11 An operator is a word or symbol that indicates a specific arithmetic or logical relationship between the elements of an expression. Operators are used to create conditions. Operators can include arithmetic operators, such as the plus sign (+); comparison operators, such as the equals sign (=); logical operators, such as the word “And”; concatenation operators, such as & and +; and special operators, such as “Like,” “Between,” or “In.”

12. a lesson approach © 2011 The McGraw-Hill Companies, Inc. All rights reserved. Exercise 6-5 12 In addition to operators, a condition can include one or more functions. A function is a procedure used in an expression. Most functions include multiple arguments. An argument is a reference in a function assigned as a single variable. Some functions such as “Date” do not require arguments. Other functions such as “DateDiff” contain both required arguments and optional arguments.

TypeDefinitionExamples Arithmetic operator A word or symbol that calculates a value from two or more numbers. +, −, *, /, \, ^ Comparison operator A symbol or combination of symbols that specifies a comparison between two values. A comparison operator is also referred to as a relational operator. =, <>,, >= Logical operator A symbol, word, group of symbols, or group of words used to construct an expression with multiple conditions. And, Or, Eqv, Not, Xor Concatenation operator A symbol, word, group of symbols, or group of words used to combine two text values into a single text value. &, + Special operators Like, Between, In, True, False 13 Table 2-1 Exercise 2-8

15. a lesson approach © 2011 The McGraw-Hill Companies, Inc. All rights reserved. Exercise 6-5 15 Queries often use comparison operators to evaluate data. Comparison operators allow you to evaluate numbers, text, and dates. For example, the expression “>10/17/11” would display all records with a date after October 17, 2011. The expression “>=10/17/11” would display all records with a date on or after October 17, 2011. When comparing text, fields are evaluated alphabetically. The expression <“smith” would display all records that appear in a dictionary before the word “smith”.

When an AND condition is placed on multiple fields, the keyword is not entered. When more than one field contains a condition on the same Criteria row, then an AND condition is created automatically by Access.

A subdatasheet is created by defining a Subdatasheet Name as a query property. The sheets must be linked by a common field. You will now modify qryMgtContacts by linking the ManageID field between the tables management and facilities.
