You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

An expression task allows us to calculate an expression, usually to store this value in a variable.

The advantage of an expression task is that you can calculate variables without needing to create cumbersome script tasks.

Here's what the 2012 expression task looks like (in part):

The expression task allows us to set one variable equal to the sum of two other ones!

Time now to look at what should perhaps have been number 1 on my list: undoing and redoing commands in SSIS.
