Join Ron Davis for an in-depth discussion in this video Understanding parameters, part of SQL Server Integration Services (2015).
- In SQL Server Integration Services,…we use parameters to assign a value to properties.…And we use these properties during execution.…Parameters are different from variables…in that they are intended to hold a literal…that does not change during execution.…Whereas variables may.…Parameters, like variables, do have a scope.…A parameter can be scoped to either the package level…or the project level.…
And if you remember, variables have the ability…to scope into the task level,…which we can't do with parameters.…Paramters have three types.…And types may not be a good word here,…but let me explain it.…There's execution, and that's assigned…to a specific instance of a package executing.…So if you will, if you think about a package…that does something, you know,…does some kind of a Data Flow,…and that package may actually execute…on a number of different SQL servers.…
So each instance of the package executing then…has a execution value for the parameter.…There's server.…Server is a value assigned within…the scope of the project after deployment.…
