It stores procedure database components. Informatica uses the stored procedure in a manner that is similar to database tables. Stored procedures are sets of SQL instructions that require a certain set of input values, and in turn the stored procedure returns output values. This way, you either import or create database tables and import or create the stored procedure in the mapping. To use the stored procedure in mapping, the stored procedure should exist in the database.

Similar to Lookup transformations, stored procedures can also be connected or unconnected transformations in Informatica. When you use a connected stored procedure, you pass the value to stored procedures through links. When you use an unconnected stored procedure, you pass the value using the :SP function.
