Using the Destination Component
After Establishing a Connection to the data source, add the CData Oracle OCI destination component to the workflow to load data into Oracle OCI.
Writing to Oracle OCI in a Data Flow
Follow the steps below to connect to Oracle OCI and update data.
- In the SSIS Toolbox, drag the CData Oracle OCI destination component into the Data Flow Task.
- Connect the output of a source component to the CData Oracle OCI destination component.
- Double-click the CData Oracle OCI destination component. The CData Oracle OCI Destination Editor dialog is displayed.
- In the Connection Managers menu, select an available CData Oracle OCI connection manager, or create a new instance if one is not already available.
- In the "Use a Table" option, select the table to update.
- Select the data manipulation action. See below for more information on each action.
- On the Mappings tab, configure the mappings from source to destination. By default, outputs from the source component are automatically mapped with the same name as the columns in the table you selected. You can further update these selections.
NOTE: Read-only columns are not visible among the destination columns since they cannot be written to.
QueryPassthrough Support
NOTE: For performance reasons, Oracle OCI does not support QueryPassthrough when using the Destination component. Make sure you use a connection with QueryPassthrough set to False to use this component.Command Execution
When you execute the data flow, the component executes one of the following operations to update the destination table.
Insert
The component takes the mapped values and attempt to insert the data as new rows into the table. By setting the OutputKey property to True in the destination component's properties, you can retrieve the results of the insertion in the error output of the component with the 'Redirect row' error behavior.
Update
The component attempts to update an existing row based on the primary key provided. The primary key column must be mapped, and it must not be null. By setting the OutputKey property to True in the destination component's properties, you can retrieve the results of the update in the error output of the component with the 'Redirect row' error behavior.
Upsert
The component uses the primary key to decide if a row is to be inserted or updated. If the primary key column is mapped and it is not null, the component attempts to update an existing row based on the primary key provided. If the primary key is not mapped or if it is null, the CData Oracle OCI Destination Component attempts to insert the data as a new row. By setting the OutputKey property to True in the destination component's properties, you can retrieve the results of the upsert in the error output of the component with the 'Redirect row' error behavior.
Delete
The component attempts to delete an existing row based on the primary key provided. The primary key column must be mapped, and it must not be null.
