This document discusses variables and expressions in SSIS packages. It begins with an introduction and Q&A section on variables and their uses. It then demonstrates how to work with variables using the Variables window and in Execute SQL tasks. Expressions are introduced as combinations of symbols that evaluate to single values. Demos are presented on creating time stamped log files, using operators with variables, and using variables and expressions in tasks, connection managers, and precedence constraints. The document concludes with a summary of the topics covered and resources for further information.

4. Variables
 Variables store values
 Types of variables: user-defined variables and system variables
 The names of user-defined and system variables are case sensitive.
 Parameter names and marker in Execute SQL task according to connection type:

6. Expressions
 An expression is a combination of symbols
 identifiers
 Literals
 functions
 and operator
that yields a single data value
 Expressions are evaluated at the time it accessed
 There are many ways to use expressions:
 Tasks
 Variables
 Connection Managers
 Precedence Constraints
