Join Ron Davis for an in-depth discussion in this video Understanding variables, part of SQL Server Integration Services (2015).
- Variables in Integration Services…are the same as variables…in any programming language.…Of course they call them variables,…because we change what they hold…so that we can pass different values through,…varying the value.…If we come up in here into the tool bar…and select SSIS, and select Variables,…now you see the little variable pop up,…and we can go and create a variable.…We already have a variable created,…by the way, it's Count, we're going to use that.…We'll create a new variable,…just pop it in and the default name…is Variable, clever.…
Variables also have the concept of a scope.…A scope means where other things…can act on that variable,…so that it could change the value…of what the variable contains,…and also where it can be read from.…Now scopes have either a package,…or an executable range.…So if I come down here,…and I want to change the scope,…say, of this variable that we're creating right here,…I'm going to click this little move,…and now I have different executables…and an executable is a task.…
And if I change the scope…
