SSIS means that you can carry out a lookup on information in the midst of a job, utilizing referenced information from any OLE DB supply. It’s a helpful function that lets you verify on the validity of knowledge, or interpret it earlier than continuing.

There is likely to be instances when growing a SQL Server Integration Providers (SSIS) package that you just wish to carry out a lookup with a purpose to complement or validate the information in your information move. A lookup permits you to entry information associated to your present dataset with out having to create a particular construction to help that entry.

To facilitate the power to carry out lookups, SSIS contains the Lookup transformation, which offers the mechanism essential to entry and retrieve information from a secondary dataset. The transformation works by becoming a member of the first dataset (the enter information) to the secondary dataset (the referenced information). SSIS makes an attempt to carry out an equi-join based mostly on a number of matching columns within the enter and referenced datasets, similar to you’ll be a part of two tables in in a SQL Server database.

As a result of SSIS makes use of an equi-join, every row of the enter dataset should match at the least one row within the referenced dataset. The rows are thought of matching if the values within the joined columns are equal. By default, if an enter row can’t be joined to a referenced row, the Lookup transformation treats the row as an error. Nonetheless, you’ll be able to override the default habits by configuring the transformation to as a substitute redirect any rows with out a match to a particular output. If an enter row matches a number of rows within the referenced dataset, the transformation makes use of solely the primary row. The way in which wherein the opposite rows are handled will depend on how the transformation is configured.

The Lookup transformation permits you to entry a referenced dataset both via an OLE DB connection supervisor or via a Cache connection supervisor. The Cache connection supervisor accesses the dataset held in an in-memory cache retailer all through the length of the package execution. You may as well persist the cache to a cache file (.caw) so it may be obtainable to a number of packages or be deployed to a number of computer systems.

On this course we are going to create an SSIS package and implement a lookup logic to it.
