Join Ron Davis for an in-depth discussion in this video Performing joins with the Merge transformation, part of SQL Server Integration Services (2015).
- Okay, now we're going to look at merging data.…We have two packages here and the first…is going to use the merge…and the second is going to use the merge join.…They are slightly different.…First, let's go through and look at doing merging,…and what merging's going to do is it's just…going to take data from one source…and data from another source…and then put them together or merge them.…
Now, both merge and merge join require sorted data.…So what we have here is a connection into…this little color database that we set up,…which really just has an ID, one, two and three…and red, white and blue.…And then we have another one that we set up.…One, two and three.…Green, pink and purple.…And we'll close that on out.…Then we're gonna come into a sort…and each one's going to be sorted.…Now we're going to just pass through the color name.…
That's really what we're going to join in here.…And our ID is how we're going to do the sort order.…So we're going to sort on ID and it's in ascending,…you could do it in descending…or whatever you prefer.…
