- Alright, let's take a look at using Expressions…in packages to make our packages dynamic.…We're going to start here, we've used Expressions already…and we're going to take another look at them here…and then later on in the course we'll come through…and look at them yet again.…Particularly when we go into taking a look…at using Precedence Constraints in such a manner…to control our data flow better.…So what we have is control flows up here,…where I'm gonna Execute a SQL Task,…which is just a placeholder.…
It just comes through and it does a selection,…it's just really to start my Precedence Constraints.…And I've got my Precedence Constraint down here…and if I double-click it you see I used an Expression.…If I click the ellipsis here…I go into the Expression Builder.…And what I did was I had a variable I set up, YNExecute.…And I said if it's = 0…then, we'll Evaluate the Expression and it's False,…then this will not execute.…
And this has a Precedence Constraint,…but it does not have an Expression on it,…so this is going to just execute on success.…
