Using substitution methods in Java

For this recipe, we will make a very simple modification to the IKM SQL Control Append by combining a Java variable and a substitution API. Then we will use this KM in an interface to see how the code gets generated.

Getting ready

You will need to have a project ready where the IKM SQL Control Append KM has been imported. You must also have a table that can be used as a target table using this IKM in an interface.

How to do it...

1. Rename the IKM SQL Control Append KM to IKM SQL Control Append with Variable and Substitution.

2. Add a step. Name the step Retrieve Session Number and write the following code in that step:

   <%v_sess=odiRef.getSession("SESS_NO")%>

   Tip

   There is no need to set the technology for this step: as you will see when we use the KM, no code will actually be generated for the agent to run.

3. Move this step up to make sure that it is the very first step in the KM, the same way we did it in step 6 of Using Java variables in KMs.

4. Edit the step Create...
