Data loading with the Execute SQL task

- The Execute SQL task.…The Execute SQL task is one of the handier tasks…that we have in Control Flow.…The name of the task, Execute SQL…is descriptive of what we can do.…We can place SQL statements into the…Execute SQL task, and then run them.…So, we could do things such as create tables…but it's normal to use Execute SQL…to go on down and hit a database…and to run some kind of a query.…Either a query and return a singleton…such as doing a count…or a query and return a result set…or a query and to return some type of an XML output.…

We can also run stored procedures.…So, within a stored procedure…we would just call the stored procedure…passing any parameters and then…if it passed back a result…we would bring that result on back.…I would also say that the most difficult part…of the Execute SQL task is the mapping…of the parameters when you're passing in…multiple parameters and receiving multiple results back…because the data mapping between SQL and .Net…is not necessarily a one for one…so you gotta kind of pay attention to that.…
