Parameter and Generator Notes

A batch modify operation uses non-standard key and details structures as input parameters that you must create yourself and specify as operation parameters in the UML meta-model. Each attribute of each of these structures must match some entity attribute by name and type. It is possible to use standard (generated) key or details structures also.

A warning is displayed if a batchmodify operation has non-standard details parameter, which does not include fields that cannot be null. Refer to section in Null Considerations.

Parameters - A non-standard key struct to specify the record to be modified. Note that this non-standard key may specify multiple records. In this case, all records matching the non-standard key will be updated.
A non-standard details struct containing the updated version of the data.
Return Value - None.

Generator action - The generator adds the following methods to a class containing a batch modify operation:

public void operationName$setBatchSize(final int newBatchLimit) - This method sets the batch limit for the operation (overrides the value of the curam.db.batch.limit property).
public int[] operationName$execute() throws AppException, InformationalException - This method executes the currently queued batch of statements for the operation.

Note: batchmodify operations cannot be spread across multiple client-server invocations (transaction). A batchmodify operation can only be used in an online transaction if the batch is executed before the end of the transaction.
