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.

Activities

Now that you have started playing with the Crystal Reports Designer in full Designer mode, try connecting to one of your own local databases and creating a simple listing report with different types of groupings.
