Whether you’ve been involved with SQL Server Integration Services (SSIS) for years or are just learning SSIS, you’ve probably found the learning curve of the SSIS expression language quite challenging. The expression language is a core component of SSIS that helps users make any component in an SSIS package dynamic and also helps the data flow make workflow decisions. This whitepaper walks you through a crash course in the SSIS expression language across all components of SSIS. After you complete this whitepaper, you’ll know how to use expressions in the control flow,
data flow and in connections to make your package change at runtime and maximize the full power of SSIS.
