Add Data Expressions to a Data Container

Overview

Adding data expressions to the data container is the final step in completing the creation of a data connection. For our report we need access to all the fields in the one table and only one in the other.

What is a data expression?

A data expression is the selection from a data container. A data expression can be a:

  • Data Field

    A single database field. For example, a field containing customer details such as surname or initials.

  • SQL Expression

    Returns data from a field or combination of fields based on a SQL Expression.

  • Excel Formula

    Returns data based on an Excel Function or formula.
