Chapter 18: Getting Integrated with Integration Services
We’re not going to go into real detail on this, because the options available will vary widely depending
on the particular OLE DB data source you’ve selected. Indeed, the real point of the moment is just that:
SSIS will alter the dialog to give you contextual choices that are relevant to the particular OLE DB data
source you’re using. In the preceding example, I’ve simply clicked the “Column names in the first data
row” option, and it’s time to click Next again. This takes us to choices for selecting what data we want
out of our source database. We have two choices here:
❑ Copy: This has us do a straight copy out of a table or view.
❑ Query: This allows us to select out of pretty much any operation that’s going to yield a result set.
Let’s start by taking a look at the Query option. If you choose this option and click Next, you get yet
another dialog; this one pretty boring in the sense that all it does is give you a box where you can enter
in the text of your query. (See Figure 18-5.)

In my example here, I’ve shown where we could be setting up to export a list of employees that we hired
in our first month of business. If you want to test this, you can type the query, and then try testing it
with the Parse button to make sure that the query you want to run is syntactically valid, or you can copy
it into a query window in the Management Studio and test it there. Then click Next to get to the dialog
box shown in Figure 18-6.
