updateCallback(tranID: Integer64;
timestamp: TimeStamp;
oid: Object;
operation: Integer;
tableName: String;
dropRowOperation: Boolean io;
outputRowList: JadeDynamicObject);
The updateCallback method of the JadeRpsDataPumpIF interface determines whether the row is replicated in the relational database table and, for an object create, update, or load operation, enables you to manipulate the data in the row.
The parameters for this method are listed in the following table.
| Parameter | Description |
|---|---|
| tranID | A 64-bit integer value that uniquely identifies a transaction |
| timestamp | The timestamp of the journal record that describes the transaction |
| oid | The object being created, updated, deleted, or loaded |
| operation | An integer value identifying whether the object was created, updated, deleted, or loaded |
| tableName | The name of the table being output |
| dropRowOperation | A boolean value that determines whether the transaction is replicated in the relational database |
| outputRowList | A dynamic object with one attribute for each column in the mapped relational table |
The dropRowOperation io parameter has the value false by default. If you set it to true, the row is not replicated in the relational database.
For create, update, and load operations, an attribute is added to the outputRowList dynamic object parameter for each column in the mapped relational table. The attribute names are the column names.
The attribute values are populated with default values obtained from the JADE object, including values returned by user-defined column-mapping methods. The updateCallback method can interrogate attributes and access or change attribute values.
