DB2 Upsert Configuration

Version 21.0.8222

DB2 Upsert Configuration

The Upsert action inserts or updates DB2 data. By default, if a record already exists in DB2, an update is performed on the existing data in DB2 using the values provided from the input.

Tables and Columns

If you choose Upsert for the DB2 connector, you must select a target table (or tables) from DB2. Click the + Add button above the Tables pane.

A modal appears and lists all available tables. Select the desired table and click + Add.

The chosen table appears under the Tables pane, and the columns in the table appear under the Columns pane. The connector automatically detects values that have special relevance (for example, the primary key and foreign keys) and labels them accordingly.

By default, all of the columns are selected for inclusion in the action for the DB2 connector. You can exclude individual columns by un-checking them.

Note: You can select more tables by clicking + Add and repeating this process. See Child Tables for more information.

Example ArcESB Flow

After you choose the tables and columns for the Upsert-configured DB2 connector, place the connector at the end of an ArcESB flow. The screenshot below depicts an example flow with a CSV connector, an XML Map connector, and a DB2 Upsert connector at the end:

Data in this example flow passes through these steps:

  1. The CSV1 connector supplies a CSV file that contains data.

  2. This data passes to the XML_Map connector as the Source File, which maps to the Source tree.

  3. Data from the DB2_Upsert connector passes to the XML_Map connector as the Destination File, which maps to the Destination tree.

  4. The XML_Map connector attempts to automatically map Source elements to Destination elements with the same name. You can manually change these and fill in blank mappings by dragging elements from Source to Destination.

  5. The DB2_Upsert connector performs the Upsert according to the mapping and passes the resulting data to DB2.
