Workshop

The quiz questions and activities are provided for your further understanding of the current hour's topics.

Quiz

1:What is a special field?
A1: The special fields provided in the Field Explorer are a number of system variables that Crystal Reports provides for you to use within your reports (for example, page number, file author, data date, and so on).
2:What is the difference between a formula and a SQL Expression?
A2: A SQL Expression must be written in the Structured Query Language of the Database you are using as a data source for the given report. SQL Expressions can increase the efficiency of your reports by passing the entire expression to the database to process. Formulas provide increased flexibility through a powerful library of Crystal and VB syntax, but they slow report processing performance when they must be executed on the server that holds Crystal Reports.
