Using ColdFusion Functions to Manipulate Data 248 Workshop Just to see whether you were dozing through today's discussion, here are a few quiz questions and exercises. Answers to quiz questions can be found in Appendix A at the back of the text. Quiz 1: When do ColdFusion functions require hash-mark delimiters? 2: Are function names case-sensitive? 3: Name two functions that might be used to trim leading or trailing spaces from a text string. 4: Briefly describe a date/time object. 5: In the jargon of functions, what is a token? 6: What is a mask? Exercises 1: Create a table in which at least one field contains dollar values. Add some values that contain commas for thousands, some that contain decimal points and trailing zeros, some that are whole numbers, and so on. Using ColdFusion functions, create a template that will query your table and display the results neatly aligned, each with dollar signs, commas, and two decimal places. 2: Create a table that contains the birth dates of friends and relatives. Using date and time functions, create a template that shows how many days separate two of the dates. Also list the number of weeks, years, and months that separate the dates. (If you plan to display your handiwork to others, it's best not to use older people in your comparisons.) 3: Using <CFOUTPUT>'s GROUP parameter, create a template that displays records in groups, such as all employees in Production followed by all employees in Marketing. Use UCase() to create uppercase headers to identify each group .
