What is the difference between connected and unconnected stored procedures

Run a stored procedure before or after a session. Run a stored procedure once during a mapping, such as pre- or post-session. Run a stored procedure every time a row passes through the Stored Procedure transformation. Connected or Unconnected. Run a stored procedure based on data that passes through the mapping, such as when a specific port does not contain a null value. Pass parameters to the stored procedure and receive a single output parameter. Pass parameters to the stored procedure and receive multiple output parameters.

To get multiple output parameters from an unconnected Stored Procedure transformation, you must create variables for each output parameter. Run nested stored procedures. Call multiple times within a mapping. Stored Procedure Transformation Overview.

Configuring an Unconnected Transformation. Updated March 01, Thanks for reply. I think lookup and stored procedures are both connected and unconnected transformations. Am I right? Hi connected lookup is connected directly to the mapping pipeline whereas unconnected lookup is separate from pipeline we call unconnected lookup from another transformation expression ,update strategy using :LKP fn.

Unconnected Call multiple times within a mapping. Unconnected Some of the Scenarios where we would use stored procedure transformation in Informatica. In this article, we will see how to create a connected stored procedure transformation using a simple example. We will create a stored procedure in the source database oracle to compute the sum of salary and commission of an employee.

The stored procedure is shown below:. Follow the below steps for creating the mapping and stored procedure in informatica:.

Create a workflow and session for this mapping in workflow manager. Specify the connection information for stored procedure transformation also. You are commenting using your WordPress.

There are three ways to import a stored procedure in the Mapping Designer: 1 Select the stored procedure icon and add a Stored Procedure transformation. Stored Procedure Transformation Overview: One of the important features of stored procedure is that you can send data to the stored procedure and receive data from the stored procedure.

Return Values : After running a stored procedure, most databases returns a value. This value can either be user-definable, which means that it can act similar to a single output parameter, or it may only return an integer value. If a stored procedure returns a result set rather than a single return value, the Stored Procedure transformation takes only the first value returned from the procedure.

Status Codes : Status codes provide error handling for the Integration Service during a workflow. The stored procedure issues a status code that notifies whether or not the stored procedure completed successfully.

We cannot see this value. The Integration Service uses it to determine whether to continue running the session or stop. This is useful when running a calculation against an input port.
