/ Copyright (C) 1995, 2010, Oracle and/or its affiliates. All rights reserved./ This is a User exit example for access to "Primary Key Updates" and "before images" from Updates. This example uses the PK_BF_TIMESRC and PK_BF_TIMETRG tables, which can be created using the demo_*pk_befores_create.sql scripts included with the ER release. This same script will add a stored procedure, which when executed will Insert and Update a row of data. Please be sure to "ADD TRANDATA" for the PK_BF_TIMESRC table for those databases which allow the GGSCI command, before executing. To compile this exit code, use the appropriate make or project file in this same directory. The compiles are 32bit, for 64bit, changes will be necessary in the make files as well as possibly #includes in the .c file. This example is a hypothetical business solution when a target database does not allow the Primary Key Updates. Therefore, when reading a PKUpdate record, it will change this operation into two separate records of Delete and Insert. While this is not necessary for most databases, for those databases which PKUpdates are not allow this example is not necessarily a recommended solution to this problem. It is only an example to demonstrate access to PKupdate records. This example will work for Extract and Replicat. This example will also show access to the before images of an Update. These records are typically included with the use of GETUPDATEBEFORES or the "cuserexit" option of INCLUDEUPDATEBEFORES. This is intended as a hypothetical business solution of conflict detection base on a specific column. The is an example which can only function in Replicat. The examples when used in a Replicat will also make use of the SQLEXEC functionality. Several user exit callbacks allow for access by both name or by index, examples are shown for both.
